An Industry Primer on Carbon Capture for Investment Professionals

1. Executive Summary

1.1 The investment thesis for carbon capture

Carbon Capture, Utilization and Storage (CCUS) is a critical and fast growing component of the international climate strategy. For those industry sectors with inherently unavoidable process emissions - cement, steel, chemicals - and to abate emissions from existing asset power generation infrastructure, carbon capture is one of the limited viable paths to decarbonization. This necessity informs the main investment thesis: a large, non-discretionary, addressable market driven by national and corporate net-zero goals. The sector is currently at a critical inflection point, from a niche, economically challenged sector into an emerging growth sector, supported by significant policy incentives, technological maturation, and accelerating private sector demand for tangible decarbonization solutions. For investors, CCUS provides long-duration exposure to existing energy transition solutions through investments in critical infrastructure, proprietary technology, and the emerging carbon management services market.

1.2 The carbon capture industry in one paragraph

The carbon capture industry consists of a multi-faceted value chain designed to capture carbon dioxide (CO₂) emissions at point source or remove CO₂ emissions directly from the atmosphere, thereby ensuring CO₂ does not enter and contribute to climate change. The carbon capture process has three main categories: Capture where CO₂ is separated from other gasses, Transport where CO₂ is compressed and transported by pipeline, ship or truck; and Storage or Utilization, where CO₂ is either permanently sequestered into deep underground geological formations, or used as a feedstock to produce commodities like synthetic fuels, chemicals, or building materials. The carbon capture market serves three different types of carbon emitters - hard to abate sectors, and as a means to generate high-quality carbon removal credits to offset their residual emissions.

1.3 Key metrics snapshot

While the CCUS market is set for major growth, the current market size estimates vary based on the scope and methodological framework. Market estimates for 2024 span from approximately $3.4 billion to $8.6 billion. It is expected that growth will be dynamic - various analyst outlooks include projections for 2030 that estimate the CCUS market will be between $9.6 billion to $51.5 billion, or growing at a compounding annual growth rate (CAGR) of 16% to over 24%. Further afield and at large, total global capture capacity is also expected to ramp significantly. Current estimates of capacity stand at approximately 75 million tonnes per annum (Mtpa) and is projected to exponentially grow to well over 2,000 Mtpa by 2050 in response to global decarbonization efforts.

1.4 Three things you need to know about the carbon capture industry

1. Policy is the leading economic driver: The commercial viability of most current CCUS projects relies heavily on government incentives. Policies such as the Section 45Q tax credit in the United States that grants 180/ton from Direct Air Capture, are critical as a way to de-risk a project and to entice private capital . Any investment thesis will need to assess these policies from a standpoint of stability and evolution.

2. The Value Chain is complicated and interrelated: Carbon capture is not a single technology but rather a multi-stage process (capture, transport, and storage). Capture is typically the most technologically advanced and capital intensive value chain . Bottlenecks in even one segment, such as a lack of pipeline infrastructure or available storage sites, can impede the maturity of the entire sector.
3. Two fundamentally different approaches exist: The industry is bifurcated into point source capture, which captures concentrated CO₂ from industrial facilities or power plants, or Direct Air Capture (DAC), which captures diffuse CO₂ from ambient air. Point source capture is more mature and cheaper, whereas DAC is still early-stage, has significant energy intensity, and needs credit pricing of ca. $600/tonne to have commercial viability .

2. Industry Fundamentals

2.1 Definition and scope of the carbon capture industry

The Carbon Capture, Utilization, and Storage (CCUS) industry consists of technologies and business models that have the explicit goal of capturing carbon dioxide (CO₂) in order to either prevent its emissions into the atmosphere or remove it from the atmosphere. The scope of this primer will focus on engineered or geologic capture systems, which are artificial systems that separate CO₂ from industrial processes or ambient air, and then permanently store this CO₂ geologically or convert it into products .

The value chain begins with Capture, the removal of CO₂ from other gases, usually at large stationary sources such as power plants, cement factories, or chemical plants (point source capture) or directly from the air (Direct Air Capture). The captured CO₂ will be purified and compressed and then is ready for Transport, a midstream logistic function, usually done with pipelines, but sometimes with ships, rail, or truck. The last part of the value chain is either Utilization, making commercial products from CO₂ such as concrete, chemicals, and synthetic fuels, or Storage (also called sequestration), the practice of injecting the CO₂ into very deep, secure geologic formations for permanent containment .

Although biological processes such as afforestation represent a form of carbon sequestration, the CCUS industry, from an investment perspective, is focused on the technological solutions which can provide quantifiable, verifiable and permanent carbon management at an industrial scale.

2.2 Sub-sector breakdown: Point source vs. direct air capture

The carbon capture industry fundamentally breaks into two separate, distinct sub-sectors based on where the capture process is located: at a concentrated point of emission, or from the ambient air.

Point Source Capture represents the more mature and deployed approach to carbon removal, targeting CO₂ from stationary and often more concentrated (>4% to >25% by volume) sources. Separation is more effective and efficient than DAC because of the high concentrations. Point source capture technologies can broadly be classified as belonging to one of three categories :

• Post-combustion: The most widely used methodology, particularly if existing power plants and industrial facilities are being retrofitted. This involves ''scrubbing'' the flue gases after combusting the fuel, using a solvent to absorb the CO₂
• Pre-combustion: Commonly used in industrial processes like gasification, this technology converts CO₂ from a fuel source prior to combustion. This is often more efficient but generally requires a new facility that has been built for this purpose.
• Oxy-fuel Combustion: Here we burn the fuel using nearly pure oxygen instead of air. The resulting flue gas is nearly 100% CO₂ and water vapor, making CO₂ remediation significantly easier and less expensive.

Some industrial processes, like ethanol and natural gas processing, create a nearly pure stream of CO₂ as a byproduct, leading to naturally low-cost carbon capture .

Direct Air Capture (DAC) DAC is an emerging sub-sector aimed at addressing historic and dispersed emissions by capturing and removing CO₂ directly from the ambient atmosphere. The concentration of CO₂ in the air is very dilute (~0.04%) meaning DAC is much more expensive and energy intensive than point source capture. Because DAC projects are now reliant on some form of revenue from the voluntary carbon market, where corporations purchase high-quality carbon dioxide removal (CDR) credits, it is important to note that prices have often ranged 1 to 2 orders of magnitude higher than compliance market carbon prices . That being said, DAC is viewed as a crucial component to reaching net-zero emissions, as it can offset unavoidable emissions in sectors like aviation and agriculture, which may be impossible to completely decarbonize.

2.4 History and major inflection Points

Carbon capture, in particular its foundational technologies, have existed for years. Post-combustion captures date back to the 1980s when it was used for separating CO₂ in natural gas processing, among other industrial applications . Prior to now, CCUS deployment has been slow and sporadic due to (i) high costs, (ii) lack of strong supportive policies, and (iii) limited good economic use cases outside of enhanced oil recovery (EOR) where CO₂ is injected into oil fields to stimulate petroleum production. This led to CCUS being perceived as an expensive niche technology with limited climate impacts .At the end of the 2010s, the industry began a major inflection point, leading into the 2020s the momentum significantly accelerated. This momentum was catalyzed by a perfect storm of catalysts:

1. Strengthened Climate Policy: The Paris Agreement established a global framework for decarbonization, prompting nations to set more ambitious targets for emissions reduction. This was followed by major legislation, and most prominently, the U.S. Inflation Reduction Act of 2022, which significantly modified the value and accessibility of the 45Q tax credit, essentially rewriting the economic equation for CCUS projects .
2.  Corporate Net-Zero Commitments: A wave of corporations emerged with ambitious net-zero commitments, generating substantial demand for both emissions abatement solutions for their own operations and high-quality carbon credits to offset residual emissions.
3. Technological Maturation: Key capture technologies have not been particularly cheap, but costs are beginning to decline, and operational track record is growing.

This trifecta has changed the industry landscape. A large and growing project pipeline has formed in the global development pipeline, with the International Energy Agency (IEA) reporting over 700 projects by 2024, up from just a handful a few years earlier .

2.5 Industry lifecycle position: An emerging growth story

The carbon capture industry is moving from a nascent phase that focused on demonstration and in-situ validation, to an early growth phase. The technologies are not new, but their use as a climate solution at a scale beyond small demonstration projects is just now beginning to gain commercial momentum. The industry's current position is characterized by accelerating adoption, buoyed by tailwinds from strong macroeconomic conditions, albeit with barriers typical of an emerging industry.

Evidence of its growth-stage classification includes robust top-down forecasts, with several analysts predicting sustained, double-digit annual growth for the foreseeable future . Long-term projections predict more than 25x increase in capture capacity to fulfill climate targets by 2050 . This growth is evidenced by the project pipeline, where there is an growing list of established industrial players and innovative technology start-ups.

However, the industry has not matured. It remains highly capital intensive, with project costs typically being over a billion dollars, and returns are driven significantly by durability of policy . It will also take time and significant investment in midstream transport and storage infrastructure before the full value of capture technologies can be realized. As the industry scales, the capital markets will benefit from learning-curve effects, standardization, and economics of scales to drive down costs, increase returns, and reduce reliance on direct subsidies over the long term. Altogether, the combination of proven technological principles and a massive, policy driven market opportunity defines the emerging growth story of carbon capture.

3. How the Industry Works

The carbon capture industry is structured around a complex, interrelated value chain that segregates activities into three distinct stages: 1) Capture, 2) Transport, and 3) Storage or Utilization. Each of these stages employs different technologies, has different economic drivers, and faces unique challenges in commercial use. While these activities can happen within a single project, the trend is moving towards specialization where companies focus on one portion of the value chain; thus, providing differentiated investment opportunities across the value chain . Like any functional value chain, it is critical to understand how each link operates within the larger value chain towards the common goal of reducing CO2 emissions. Successful deployment of CCUS at scale requires co-development and effective operation of all three segments of the value chain .

***

3.1 The carbon value chain: capture, transport, and storage

The CCUS industry is structured around a sequential, three-part value chain: capture, transport, and storage or utilization. Each of these stages employs different technologies, has different economic drivers, and faces unique challenges in commercial application. While these activities can occur within a single project, the trend is toward specialization by a company focusing on one part of the value chain; this creates distinctive investment opportunities across the value chain . As with any value chain, it is important to understand how each link operates in the larger value chain to achieve the shared goal of reducing CO2 emissions. The successful deployment of CCUS at scale relies on the collaborative development and efficient operation of all three segments of the value chain .Capture: The first step is to separate the CO2 from other gases. It is the most technologically advanced part of the value chain and is typically the most costly. Capture technologies can generally be broadly categorized into two types of sources. Point source capture refers to the flue gas streams from large industrial facilities, including power plants, cement plants, steel mills, etc. CO2 concentrations in these streams are relatively high (typically 4-25%) so energy and costs to separate the CO2 are less unlike the capture technologies mentioned above. The capturing technology used most often for point sources is post combustion capture, where the CO2 is scrubbed from exhaust gas typically using a chemical solvent like monoethanolamine (MEA) . Other traditional capture methods include preload combustion, which captures CO2 prior to combustion of the fuel, and oxyfuel combustion, which burns the fuel in pure oxygen. In contrast, Direct Air Capture (DAC) technologies pull CO2 from the atmosphere where CO2 concentrations are 420 parts per million. Because of the diluted concentration presence, DAC carbon capture is much more energy-intensive and costly than point source capture.

Transport: Once captured and purified, the CO2 is compressed into a dense, liquid-like supercritical fluid and diluted for transport to a storage or utilization site. CO2 in its supercritical form is efficiently transported. The primary method of transport for large quantities over land is through pipelines, similar to natural gas pipelines but designed to address its unique corrosive properties and high pressure. Alternative methods for transport of smaller quantities or when pipelines aren’t practical (e.g. offshore transport) include ship, rail, or truck. Development of large-scale CO2 pipeline networks, particularly as multi-user "common carrier" infrastructure, is considered an essential piece of scaling the industry as it allows for multiple capture facilities to connect to a shared storage hub, reducing transport costs per unit .

Storage and Utilization: The final step in the CO2 value chain determines the ultimate fate of captured CO2.

• Storage (Sequestration): This step includes the permanent injection of CO2 into deep, underground geological formations for long-term isolation from the atmosphere. The ideal storage sites are porous rock formations, which are typically deep saline aquifers (containing unusable, salty water) and depleted oil and gas reservoirs, all thousands of feet below the surface and sealed with an impermeable caprock layer . Integrity of the site is extremely important, requiring geological considerations about integrity, risk assessment, and long-term monitoring, measurement and verification (MRV) to guarantee permanence and no leakage.
• Utilization (CCU): This pathway involves the usage of captured CO2 as a feedstock to produce commercial products. CO2 is already being used for Enhanced Oil Recovery (EOR) which involves injecting CO2 into mature oil fields and increases petroleum extraction and a portion of CO2 remains stored in the reservoir. Other growing utilization pathways include producing building materials (e.g., curing concrete where the CO2 is mineralized and permanently bound), producing synthetic fuels (e-fuels), and creating chemicals, plastics, and carbonated beverages. The benefits (economic and climate) of utilization vary widely. Generally, pathways that lead to durable, long-term sequestration lead to greater climate benefit versus pathways where the CO2 is quickly re-released to the atmosphere.

3.2 Business model archetypes

There are a number of different business models which have emerged as the CCUS industry matures, each with different risk-return profiles for investors. The models are intended to address the capital costs and operational complexities of the CCUS value chain by structuring how different players work together and share responsibilities.1. Vertically Integrated Owner-Operator: In this model one entity (typically a large industrial or energy company) develops, owns, and operates the entire CCUS value chain for its own facility. The company would operate and be responsible for the capture plant from their site, own and operate the dedicated transport pipeline, and own, operate and be responsible for the geological storage or utilization facility. This model provides the highest amount of execution and operational control, but also centralizes the sizable capital expenditure and liability on a single balance sheet. This model is common for large-scale projects that are larger emitters with the financial capacity and technical strength to manage all three segments of the CCUS value chain, while also benefitting from the additional revenue stream of CO2 used for EOR.

2. Carbon Capture as a Service (CCaaS): This is a specialized model that creates value chain unbundling, which allows industrial emitters to decarbonize, but not fully bear the upfront capital cost of a capture facility. A third-party CCaaS provider will finance, build, own, and operate the capture equipment on the emitter site. The emitter will pay a recurring service fee, typically on a per-ton-of-CO2-captured basis, following a long-term service agreement. This shifts some or all technology and operational risk to the specialist CCaaS provider and makes capturing CO2 more accessible to a much wider spectrum of industrial emitters. Once the capture is produced, the CCaaS provider then has responsibility for marketing of the captured CO2 and/or transporting it to its permanent storage or utilization asset.

3. Transport and Storage as a Service (T&SaaS): This model is similar to the midstream segment of the oil and gas Industry and is focused on developing the multi-user shared infrastructure broadly related to storage and transport. A T&S provider would play the role of a CO2 management utility and develop and operate large-scale pipelines and geological storage sites to serve multiple industrial emitters in a regional area. The providers would charge a tariff for transporting and permanently sequestering the CO2, creating a steady and long-term revenue stream based on throughput volume. This service model is critical to the realized value of CCUS and enables "industrial hubs" or "clusters" where even greater economies of scale in costs will be realized . This service model allows capture project developers and industrial emitters to leverage their strengths while not needing to become experts in pipeline logistics or subsurface geology.

4. Pure-Play Carbon Removal: This business model has the closest association with Direct Air Capture (DAC). DAC companies are developing proprietary technology to remove CO2 from the atmosphere, and the credits they generate are the only product sold. This product is a verifiable carbon dioxide removal (CDR) credit. Each CDR credit represents one ton of CO2 permanently sequestered. These high integrity CDR credits are sold on the voluntary carbon market to corporate clients seeking to offset ~800 million tons of unavoidable GHG emissions  and meet their net-zero targets . This model is successfully less about managing an industrial process waste stream and more about providing a premium environmental service with a direct revenue line to the market price and demand for high-quality carbon removal .

3.3 A deep dive into unit economics

The economic feasibility of any CCUS project comes down to its "levelized cost," or total lifecycle (capital and operational) cost per metric ton of CO2 captured and managed. This key metric varies widely depending on the source of CO2, the respective technology used, and project scale. Capture Costs: Capture is often the costliest and most energy-intensive component of CCUS, making up the largest share of overall costs. This is primarily determined by the concentration of CO2 in the gas stream.

• High-Purity Sources: As an example, if an industrial process produces a nearly pure stream of CO2, the capture costs will be the lowest. The best examples of this are ethanol fermentation and ammonia production, where the capture costs will range from $15 to $25 per ton. The process in this CCUS scenario is primarily dehydration (removing water) or simply compressing the CO2 stream, rather than requiring complex chemical separation or purification .
• Point Source Industrial/Power: For more dilute flue gas sources, such as natural gas power plants, cement kilns, or steel furnaces, the costs are significantly higher. Each industry and project are different, but the typical range for capture of CO2 flue gas is $50 to $120 per ton (as an example) of CO2 captured.
• Direct Air Capture (DAC): DAC is the most costly method, primarily due to the extremely low concentration of CO2 in ambient air. The current costs are estimated to be between $135 and $350 per ton, but the technology developers have stated they will target costs below $100 per ton by 2030 and many have different methods to improve costs by advancement in technology and economies of scale if developed.

Transport and Storage Costs: These are incremental costs added to the costs for capture. Transport costs are related to distance, volume, and topography. While you could theoretically truck or rail small amounts of CO₂, pipeline is the most economical method for large-scale deployment. Shared CO₂ pipeline corridors through joint venture projects will help reduce transport costs for large commercial projects that can utilize scale. Storage costs are very site-specific and include site characterization, well injection, and long-term monitoring. In total, general estimates for setting up a pipeline and storage network at large scale suggest an average transport and storage cost of $17 to $23 per ton of CO₂ by 2050.

Economies of Scale: CCUS developments historically benefit from significant economies of scale. The capital costs for capture facilities usually follow the "0.6 to 0.8 power rule," meaning if you double the capacity of the plant, you will increase the capital costs by only 60–80%. This leads to lower average capital cost per tonne for larger CCUS builds.

3.4 Customer dynamics: Who buys carbon removal?

The demand side of the carbon capture market has a diverse set of customers with varying motivations with varying levels of engagement resulting in market segments.

1. Compliance-Driven (Industries): To elaborate, the foundational customers are large industrial emitters that are highly regulated. In regions with carbon pricing mechanisms (like emissions tax or cap-and-trade) these large companies are motivated to install CCUS to not have to pay for their emissions. The price of carbon allowances or the level of the carbon tax creates a financial benchmark in that the cost of CCUS (ideally) needs to be as close to this benchmark as possible. This customer base is typically in hard-to-abate sectors such as cement, steel, chemicals, and fossil fuel power generation .2. Voluntary Corporate Buyers: An emerging and sizeable market of corporate customers purchasing carbon removal on a voluntary basis is rapidly growing. These corporations have their own internal climate goals, like science-based targets or net-zero pledges. Corporations in the technology, finance, and retail sectors tend to be less price-sensitive than other buyers, as the quality and permanence of the carbon removal becomes a slight priority to buyers. These voluntary corporate buyers of high-integrity CDR credits are the primary customers of DAC projects to offset their residual carbon footprint . The price of these credits is often cumulative, to carbon removal, indicating that corporations view this purchase as a viable option to reach their climate goals. Corporate carbon credits purchases has experienced exponential growth, representing strong demand for solutions out there in the market that promote verifiable and permanent carbon removal solutions .
2. Low-Carbon Product Customers: CCUS allows industrial producers to offer "green" or "low-carbon" premium products, where, if using CCUS, the costs related to carbon capture are embedded into the price of a differentiated, higher-value commodity. . If customers in various industries - construction, automotive, and consumer goods - are going to pay a premium for low-carbon steel, concrete, or fuels, it is for related linear and net-zero value chain principles. Products that will ultimately decarbonize their supply chain or reach their sustainability goals create a business-to-business (B2B) market.
3. Oil and Gas Producers (for EOR): The oil and gas industry has traditionally been the largest customer for captured CO2, purchasing it for the purpose of its use in Enhanced Oil Recovery (EOR). Although CO2 use for EOR offers a crucial source of revenue to many early CCUS projects, discussion has been raised related to the process being in alignment to long-term climate goals. This market does remain as an important economic driver/participant in certain regions of the country (and world) and exists, in-part, because of tax incentives benefiting both EOR and storage .

3.5 Supplier and input dynamics

The development and operation of CCUS facilities are incredibly reliant on a specialized supply chain of materials, equipment, energy, and expertise.

• Energy is a significant input to carbon capture. The capture plant has a parasitic load to the host facility with significant power demand. Energy consumption directly relates to operating costs and has an influence on net project carbon benefit. Projects utilizing renewable electricity or waste heat have a better environmental profile, and often better ESG references, than their counterparts using unabated fossil fuels .
• Specialized Equipment and Chemicals: The supply chain of carbon capture involves manufacturers of core process equipment that includes large-scale absorbers, stripper columns, compressors, and sophisticated membrane modules. For the solvent-based capture systems that are now prevalent, the supply of chemical solvents, or amines, and related chemicals for drying the CO2 (such as triethylene glycol) are critical for the ongoing operation of the capture plant .
• Steel and Construction: CCUS infrastructure build-out associated with pipelines, carbon steel for the pipe, stainless steel alloys for corrosive environments within the capture plant, concrete for foundations and structures. This built-out requires a skilled workforce for engineering, procurement, construction (EPC), and ongoing operations and maintenance (O&M).
• Pore Space and Geological Experience: For projects with permanent carbon sequestration, the geology is a basic input. This requires at a minimum securing the legal rights to inject CO2 into the deep subsurface "pore space" and also contracting suppliers of geological and geophysical services, including site characterization, seismic surveying, reservoir modeling, and drilling to ensure the chosen storage site is safe, secure, and permanent.

4. Industry Economics

The economics of carbon capture, utilization, and storage (CCUS) is not a function of its technology but instead is governed by policy, market incentives, and project specific factors. In contrast, CCUS is somewhat unique from other industries that produce tangible goods and are sold into a pre-defined market. The CCUS industry is, to a large extent, a service industry that produces a good that is emissions reduction/removal; it is external factors such as regulations and corporate climate commitments that define the value of the service. The economic viability of the industry is determined by developing an understanding of its revenue drivers, cost structure and evolving market conditions. For investors, the unique investment profile of CCUS - significant opportunities but also potentially large risks that are dependent on the availability of new government incentives, carbon market prices, and the extent to which technological advancements lower CCUS costs - are at play.

4.1 Primary revenue drivers

There are many revenue sources for CCUS projects. Primarily, the majority of CCUS projects rely on government incentives for monetizing carbon as an asset; absent these measures, the vast majority of CCUS projects would not be feasible and economics would not be viable.

The single largest revenue driver in the United States, specifically, is the Section 45Q Tax credit which was improved under The Inflation Reduction Act (IRA) of 2022. The IRA increased the value of the credits and decreased the eligibility threshold, which was significant development milestone for the growth of CCUS projects. For point source capture projects that permanently sequester CO2 in saline geologic formations, the 45Q tax credit value is 180 per metric ton of CO2 if the CO2 is permanently sequestered ( id:33, 41). The credits create a predictable long-term revenue stream which is critical to financing the development of projects, creating effectively a government-provided market for captured carbon.

In addition to the 45Q tax credit revenue, the second largest CCUS revenue source is the sale of carbon credits in compliance and voluntary markets. In compliance markets, and/or regulated emissions, such as the EU Emissions Trading System (EU ETS) or California's Cap-and-Trade program, emitters can purchase credits to meet state or federal compliance. As these cap-and-trade systems continue to tighten, ultimately the price of allowances is expected to increase providing a larger market pull for CCUS projects.

Also, the voluntary carbon market (VCM) plays a significant role in buying DAC credits. Companies with aggressive net zero targets are willing to pay a premium for high-quality, permanent carbon dioxide removal (CDR) credits to offset their remaining or residual emissions. The price of DAC credits in the VCM vary tremendously, and ranged from $100 to over $2000 in 2022; with the latest published average price being $490/ton . Different project attributes including, technological type, permanence, and timing for delivery can all impact DAC credit price. Most early stage DAC projects will require secured long-term offtake agreements of these premium-priced credits to create investor and project developer confidence to realize projects .

Finally, revenue sources can come from utilization of captured CO2. Use of carbon was primarily for EOR (Enhanced Oil Recovery) to increase production from depleted oil fields. While this provides direct revenue, it is largely considered less in line with net zero targets or deep decarbonization. There continues to be new utilization pathways for captured CO2 as feedstock for products such as synthetic fuels, chemicals and building materials (concrete) etc. Selling low-carbon attributes end-products, for example as "green steel" or "green cement" can also allow producers to charge a premium which can be considered an indirect premium price revenue attributable to the CCUS industry .

4.2 Cost Structure Analysis

The cost structure of CCUS is characterized by high capital expenditures (CAPEX) and substantial ongoing operational expenditures (OPEX); costs can vary immensely based on the capture source and technology.The largest component of project cost is CAPEX; capture alone accounts for approximately 75% of the total initial investment . The costs are for the engineering, procurement, and construction of the capture facility, which includes the equipment (e.g., absorbers, strippers, compressors, and dehydration units). A large-scale project can have an upfront cost in excess of 1.3 billion . Capital costs also benefit from economies of scale, which typically scale to a power of 0.6 to 0.8 with the size of the facility. A doubling of plant capacity will not double the capital cost .

OPEX consists of the costs of energy, labor, and maintenance. Energy is the largest operational cost and a key parameter in a project's carbon footprint/overall economics, specifically the capture process that is solvent or thermal swing (highly energy intensive). Thus, because of this sensitivity, CCUS costs depend on regional energy prices .

The cost of capture fundamentally is dictated by the concentration of CO2 in the source gas stream.

• High-Purity: For industrial processes that produce a nearly pure stream of CO2 such as ethanol production or natural gas processing, capture costs are very low at $15 to $25/ton .
• Dilute Point Sources: Capturing CO2 from dilute streams of flue gas at facilities such as cement plants or conventional power stations is more complicated and expensive, costing somewhere between $40 to $120/ton .
• DAC: Lastly, as CO2 is present in the atmosphere at a very low concentration (~420 parts per million), DAC would be the most energy-intensive and expensive form of capture. Current costs estimating, depending on the technology and maturity of projects, are in the range of $135 to over $1,000/ton  .

There are additional considerations for transport and storage. Where pipelines are not an option, transport via truck, rail, or ship can prove to be prohibitively expensive for large volumes. Building new CO2 pipeline infrastructure is also capital intensive with estimates of a nationwide network costing hundreds of billions of dollars. However, once pipelines are constructed, shared pipeline networks can decrease transport and storage costs to an average of 23/ton .

4.3 Margin analysis and profitability levers

Profitability in the CCUS industry is a delicate balance between the high costs of capture and the value from policy incentives and carbon markets. Margin on a per ton basis is the primary metric for project health.

For a point-source project in the U.S. the profitability assessment is fairly straightforward. If the project has an 50-25-600/t, a 180/t tax credit while still receiving a 600/t that covers its cost . This dependency on the nascent and volatile VCM is a major downside of the DAC sub-sector.

There are a number of levers that could be pulled to improve project margins:

• Technology and Efficiency: Technological advancements that lower the energy penalty of capture, such as Climeworks Generation 3 technology that could reduce electricity usage by 50%, will lead directly to lower OPEX and higher margins overall .
• Economies of Scale: Larger projects generally have lower per ton capital costs, and therefore better overall financial returns. This will continue to create the trend towards large-scale projects and regional hubs.
• Infrastructure Synergy: If capture facilities are located close to suitable storage sites or integrated into shared pipeline corridors, transport costs could decrease significantly - one variable that can erode margins .
• Favorable Policy: Future increases in the value of tax credits and potential action on a national carbon price could fundamentally improve margins across the entire industry.

4.4 Capital Intensity and Returns on Investment

CCUS is a high-capital intensity industry. The requirement for massive specialist facilities results in a large upfront investment relative to the annual revenue. This high capital intensity means that returns on investment (ROI) are very sensitive to long-term assumptions around revenue stability and ongoing operational performance.

Payback periods for CCUS projects can be long, in the range of a decade or longer, which requires patient capital and a stable and predictable policy landscape. The 12-year term of the 45Q tax credit affords a degree of revenue certainty that is critical for investors and lenders to finance these capital-intensive investments. Nevertheless, the risk of future policy changes is a particular concern .

ROI is driven by the spread between the all-in costs per ton (including CAPEX amortization, OPEX, transport, and storage) and total revenue per ton. Due to the high upfront CAPEX investments, projects must operate at high utilization throughout their planned project life to generate target returns. Any unplanned downtime or project performance can materially affect profitability. For this reason, investors will place a premium higher operational risk technologies, experienced operators, and projects with secured long-term revenue contracts. The risks and costs associated with CCUS projects have acted as a substantial barrier to investment, although the amplified incentives in the IRA begin to change this paradigm .

5. Competitive Landscape

The competitive landscape of the carbon capture industry is nuanced, highly dynamic and evolving; the industry is a diverse ecosystem of participants made up of everyone from venture-backed technology startups to established industrial players. The CCUS market is not a homogenous market structure; rather, it is a fragmented landscape of solid players vying for position within different segments of the value chain. Competition will increase as the industry transitions from demonstration to commercial scale, and with competition comes the potential for strategic partnerships, mergers and acquisitions.

5.1 Market structure overview

The CCUS market can be thought of as a collaborative and competitive network of four key types of players:

1. Technology developers: These companies are focused on developing proprietary carbon capture technologies for license to customers. This group consists of both pure-play start ups, particularly in the direct air capture (DAC) space; and the research and development divisions of larger known companies. They often operate an asset-light model where technologies are partnered with companies for deployment.
2. Engineering, Procurement and Construction (EPC): Large established EPC businesses, such as Fluor Corporation, Mitsubishi Heavy Industries, and Aker Solutions, design and build large-scale capture facilities. EPC companies generally have the technical expertise and knowledge of deployment and operation of carbon capture facilities. EPC companies will often have proprietary or licensed capture technologies while also bringing the project execution capacity and expertise.
3. Industrial Emitters and Energy Majors: Companies in hard-to-abate sectors (e.g., cement, steel, power generation) are the primary customers for point source capture. Integrated energy companies such as ExxonMobil and Occidental Petroleum are major players across all elements of the CCUS value chain. The energy majors leverage subsurface expertise for storage and balance sheets to fund large-scale projects .
4. Midstream/Storage Specialists: Companies that transport and permanently store CO2. This group of companies includes pipeline operators and where the companies specifically evaluate geological formations, well injections and long-term monitoring, verification and reporting (MRV).The market is currently in a "pre-commercial" or early commercialization stage, where competition is driven less by market share and more by securing strategic partnerships, scaling technology demonstrations and using that momentum to generate a pipeline of bankable projects. A key trend has been toward vertical integration and consolidation. A prominent example is Occidental Petroleum's $1.1 billion acquisition, in 2023, of Carbon Engineering, which combined a leading DAC technology developer with an energy major that has decades of experience managing CO2 and geological storage . Similar to the acquisition by Occidental, partnerships exemplified by the announcement in 2024 of Mitsubishi Heavy Industries, ArcelorMittal and BHP to deploy capture technology at a steel plant, demonstrate the collaborative approach needed to execute complex projects.

5.2 Profiles of major players and technology leaders

While hundreds of firms are working at some level in the CCUS space, there are several that are clearly leading in technology development and projects.

Climeworks AG: Based in Switzerland, Climeworks is arguably the most recognized pure-play leader in direct air capture. Founded in 2009, Climeworks has developed a solid sorbent DAC technology using modular collectors. Climeworks has progressed from pilot projects to commercial-scale plants evidenced by its Orca and Mammoth plants in Iceland. Most recently, the Mammoth plant is designed to capture up to 36,000 tons of CO2 per year. Climeworks is focused on selling high-quality, verifiable carbon removal as a service or a contracted service with corporate buyers including Microsoft and Shopify.

Occidental Petroleum (including Carbon Engineering): Occidental Petroleum has positioned itself as a leader in DAC projects through its subsidiary 1PointFive. First, Occidental formed its DAC strategy through the acquisition of Carbon Engineering (CE), a Canadian company founded in 2009 with a liquid solvent-based DAC technology . Occidental is advancing development to build Stratos, which is projected to be the world's largest DAC plant, in Texas, with an initial capture potential of 500,000 tons per year. The company’s extensive EOR and geology experience gives it a distinct advantage in the transport and storage parts of the value chain.

Mitsubishi Heavy Industries, Ltd. (MHI): A large Japanese industrial company, MHI is a global leader in point source capture technology, specifically post-combustion applications. MHI has deployed its Advanced KM CDR Process™, developed in collaboration with Kansai Electric Power, that uses an advanced solvent (KS-1™) and has been deployed in numerous commercial-scale projects around the world. MHI’s value proposition is delivering proven, large scale and reliable capture technology solutions for industries including chemicals, power, and steel .

Other Notable Companies:

• Fluor Corporation: A large U.S. EPC firm has a portfolio of proprietary solvent-based capture technologies having been working in the CCUS sector for decades.
• Aker Solutions ASA: A Norwegian engineering company with its own modular and cost-effective capture technology focused on industrial emitters.
• ExxonMobil: The energy supermajor is ramping up investment in CCUS, planning large-scale regional hubs (Houston) and extensive geological and management capabilities .
• Carbon Clean: A UK-based company that has developed a compact, modular point source capture technology (CycloneCC) targeted toward reducing the physical footprint and capital costs for industrial emitters.

5.3 Basis of competition and strategic dynamics

Competition is occurring in the carbon capture industry on several fronts that extend beyond technology considerations to include strategic positioning and ability to execute.The main factor that drives competition is technology cost and efficiency. For any given source of CO2, technology that achieves the lowest levelized cost of capture (through both CAPEX and OPEX, especially energy use), will have a significant and competitive advantage . This is resulting in a continuous race for innovation with companies like Climeworks announcing next generation technologies that will cut costs and energy use by 50% .

Scalability and reliability are also competitive factors. For industrial emitters, the technology must not only scale up to capture millions of tons of CO2 per year, but do so reliably and at high uptime. Established industrial players like MHI and Fluor have a major advantage here over newer companies.

Strategic partnerships are critical to success. Given the complexity of the value chain, no single company can do it all. The current situation is based on consortia being formed. This is a mix of technology providers, industrial emitters, infrastructure operators, and offtakers. For example, a DAC company may pair with a renewable energy developer to apply clean power, and then pair with a specialty firm to store CO2 permanently out of the atmosphere .

A "land grab" for strategic assets, is yet another competitive dynamic. This includes ownership of intellectual property through R&D and acquisition. This is the rationale behind Skytree's acquisition of ReCarbn in order to add more DAC technology to their portfolio . This is also securing the best geological storage sites. Companies that can locate, characterize, and permit high-capacity, low-cost storage formations are going to have substantial long-term competitive advantages.

5.4 Analysis of Barriers to Entry

The carbon capture industry has significant barriers to entry that insulate current players while making it exceptionally difficult for new, unproven companies to scale.

The most significant barrier is the extreme capital requirements. As mentioned before, the capital to build a large-scale capture plant can exceed one billion dollars. This level of capital intensity makes it nearly impossible for startups to enter beyond the pilot scale without substantial venture funding or strategic corporate investment .

Technological expertise and intellectual property (IP) represents another major barrier to entry. The leading capture processes have been developed over years and in some cases, decades of research in specialized chemical engineering and materials science. New entrants must develop a technology that will be sufficiently disruptive or license existing processes that are sometimes very costly. In addition to those developments, continuous R&D investment is needed to improve efficiency and lower costs from established leaders .

The regulatory and permitting landscape is a complex and time-consuming business process. Approval for a CCUS project, especially in the U.S. requiring Class VI wells for permanent sequestration, can take years with significant environmental reviews. New and emerging companies face inherent uncertainty and time for transporting and permitting CCUS. This favors experienced players with dedicated regulatory and legal teams to navigate the complexity.

Finally, secure public acceptance and a "social license to operate" is a critical and often overlooked barrier to scale. Local community opposition to pipelines or storage sites, from safety and environmental illness concerns, create opportunities for costly delays or abandonment altogether. Companies that engage with all local stakeholders with transparency and equity have greater potential risks on project viability . Each of these barriers creates natural segmentation and potential oligopoly elements in the CCUS market. Despite the rapid growth of the market, it is likely that a small number of well-capitalized, technologically advanced, and strategically partnered players will dominate the industry.

6. External Forces

The carbon capture industry does not exist in a vacuum, and its growth, feasibility and risk profile are influenced by a constantly evolving and complex combination of external forces. For the investment professional, it is critical to understand these forces -- which include government policy, technological disruption and public sentiment -- just as much as a company's balance sheet. These forces create both tailwinds that push the industry forward and headwinds that can slow the industry down, and both can impact project feasibility and returns.

6.1 The regulatory environment and policy tailwinds

Direct government policy is the single most important external force shaping the carbon capture industry today. Unlike industries that are mostly driven by market-based supply/demand considerations at this stage of evolution, most CCUS projects economic viability is currently underwritten by direct government policy incentives and carbon pricing. Policy de-risking investment and is the another piece of the puzzle that closes the vast cost spread between current carbon capture technologies to the unabated industrial processes of the past.

The most impactful legislation globally is the United States Inflation Reduction Act (IRA) of 2022, which significantly enhanced the value of the Section 45Q tax credit . The 45Q tax credit is the primary policy driver for CCUS projects in the United States, and it is responsible for the announcement or development of more than 270 projects as of mid-2025 . The IRA made some very significant changes: increased credit values, extended construction deadlines, and introduced a monetization option that opened credit access to investors. Projects that commenced construction after December 31, 2022, and met the prevailing wage and apprenticeship labor requirements, saw the credit for point-source capture with permanent geologic storage increased from $50 to $85 per metric tonne and the credit for direct air capture (DAC) with permanent storage increased from $50 to $180 per tonne .

Furthermore, the IRA extended the "commence construction" window by seven years to the beginning of 2033 for qualified projects and allows for the tax credit to be claimed until 12 years following the project start date. The IRA also introduced both direct pay and transferability options for developers without adequate tax liability, so they either received a cash payment from the government for the first five years, or they can sell their credits to other taxpayers . This has created project financing opportunities for startups and developers who historically could not leverage the credits in a cost effective manner.

While other countries are not as far along in government support, they are following a similar trajectory. For example, the European Union's Net-Zero Industry Act targets a very aggressive goal of 50 million tonnes per year of CO₂ storage capacity by 2030, thereby coordinating a multi-country strategy to build out CCUS infrastructure . This type of global policy creates a more predictable and long-term demand signal for CCUS technologies and services.

6.2 Macroeconomic and political sensitivity

While the carbon capture industry is buoyed by favorable policies, it remains sensitive to macroeconomic conditions and political changes. Because project economics are tied to government subsidies, any perceived instability in policy will inhibit long-term capital commitments. The significant upfront costs, often exceeding $1 billion (CCUS projects generally have long lead times), create the need for investors to have confidence in incentives such as the 45Q credit program being durable over the life of the investment . Political volatility is a risk factor, and future changes in government administration could have efforts to try to modify or repeal supporting legislation which creates even more uncertainty .

In addition, the fiscal aspects of the incentives are coming under pressure. The expansion of 45Q will undoubtedly be helpful in catalyzing the industry, however there are concerns about the final tally to the taxpayers, especially given the analyses have suggested much higher outlays than were originally estimated by the government . This potentially creates future political pressure to scale down the program.

Moreover, broader macroeconomic factors are also in play. Interest rate changes affect the cost of capital for these highly capital-intensive projects. A recent increase in venture capital funding of CCUS experienced a 139% year-over-year increase to $700 million in 2024 primarily due to the IRA, but the overall interest rate environment is also more favorable now . A return to a high rate environment slows down investment activity, particularly in early-stage companies.

6.3 Technology trends and potential disruption

The carbon capture industry is characterized by high technological turnover which creates both opportunity for cost reduction, and the fear of technological obsolescence. The primary barrier to widespread deployment outside of subsidy-supported is the capital costs of capture technologies. Capture technology costs for well-established post combustion capture technologies on dilute flue gas streams (cement plant, power plants) generally range from 120 per tonne, while today's DAC technologies can be $600 to over $1,000 per tonne . The only central technological trend is, as one would expect, to lower the "cost per tonne" of capture through improved solvents, novel materials, and process efficiencies to lower the capital and/or operating costs.

For example, global leader in DAC technology, Climeworks announced its Generation 3 technology expected to reduce energy consumption by 50% pending the reduction of cost by 50% compared to the previous generation, with a target of $250 to $350 per tonne by 2030 . At the same time researchers are looking for entirely new methods of capture, such as cryogenic carbon capture (freezing CO2) and advanced nanomaterials (MOFs) which promise the highest efficiency and lower energy penalties . The fear of an emerging disruptive technology that could significantly undercut the cost structure of a current incumbent is always a risk consideration for investors who are backing particular technology platforms. There is a clear expectation that at least a "second wave" of more advanced and lower cost DAC technologies will emerge in the next 10 years that will displace the first generation solutions .

6.4 Material ESG considerations and risks

As an industry that is central to the climate transition, CCUS is under significant ESG (Environmental, Social, and Governance) scrutiny. Investors must navigate an evolving ESG landscape that incorporates environmental risks, social impacts, and governance requirements.In addition to the environmental side, we also have the social side. For CCUS projects, developing a "social license to operate" remains a challenge. Proposed CCUS pipelines and their storage sites are not always welcome by communities. While there are many reasons for opposition, such as safety, land use, and property value, it is important to note that the local ecosystems may be negatively impacted. Local communities are typically under no obligation to provide input or participate in the project, therefore, a failed outreach or engagement process with the local community who will be directly impacted by the project (particularly indigenous communities), can lead to ultimately delays of the project for which the direct costs can be difficult to ascertain.

7. Investment Framework

Investing in the carbon capture industry will require a different investment analytical framework to reflect the industry's unique economic drivers, technological uncertainties and dependencies on policy. Conventional valuation techniques must be revised, and the analyst's due diligence must extend beyond the financial statements of the company, to include consideration of geologic, technical and regulatory factors. Ultimately, being able to select winning technologies, well-structured projects, and management teams that can navigate this new marketplace, is critical to the success of the investor.

7.1 Best-fit valuation approaches

Valuing carbon capture companies in particular, but also involving carbon capture usage and storage (CCUS) companies, particularly at the pre-revenue or early commercialization stages, is particularly daunting. From the analyst perspective, discounted cash flow (DCF) is a core analytical tool, but is limited at times dependent upon and even exacerbated by substantial uncertainty around key inputs. In this case, cash flows fundamentally depend on future price of tax credits (e.g., 45Q), prices of voluntary or compliance carbon credits and estimates of operating costs associated with the technology. Each of these inputs is subject to volatility.

Given the significant uncertainties, the most practical approach is multivariate. Accordingly, the analyst will want to incorporate into models multi-scenario based evaluation.

1. Market and Transaction Comparables: As a relative valuation, this method accounts for the target company alongside publicly traded peers, or more recent M&A transactions in the CCUS space. Key metrics include enterprise value to CAPEX ratio (EV/CAPEX), enterprise value/tonne announced capture capacity (EV/tonne), and for more mature companies, revenue or EBITDA multiples are more traditional methods of valuation. The method serves to ground valuation in market sentiment, and is reflected in actual deal structures, terms and values.
2. Scenario-Based DCF: The analyst or treat this process as a one-off and rely only on base case assumptions. Therefore, financial models will simultaneously model multiple scenarios to stress-test assumptions built around key uncertainties, such as: (a) "Policy Extension or 45Q" scenario that extends incentives, (b) "Policy Reduction" scenario that does not have benefits, or credits, (c) various carbon price forecasts, and (d) take-down cost curves of various technologies. This process generates a continuous range of values across all scenarios, and table values will consider the overall project risk. 
3. Impact-adjusted Valuation models: For investors who prioritize impact on climate, new frameworks are being devised. An example of this could be the "Discounted Carbon Dioxide Removal" (D-CDR) model that adapts an existing DCF by substituting financial drivers with climate impact drivers . Rather than discounting future cash flows, however, it discounts future tonnes of verifiably removed and stored CO2. This model is not a valuation tool, per se; however, it provides a standardised way of quantifying and comparing the climate efficacy of a different project, which is value add to the impact investor.

7.2 An analytical framework for carbon capture companies

A well-designed analytical framework for evaluating CCUS investment opportunities will be focused on four main pillars: Technology, Commercialization, Project Execution, and Policy.

Pillar 1: Technology & Cost Position

• Technology Readiness: What is the technology readiness level (TRL) of the core capture process? Is it a known solvent-based process, or a new, higher-risk approach?
• Cost Competitiveness: What is the all-in levelized cost of capture, transport and storage (20/tonne for high-purity ethanol sources to >$600/tonne for current generation DAC) .
• Energy use and source: What is the energy penalty of the capture process? Where does the energy source come from, e.g., renewables, waste heat or energy from a dedicated fossil fuel plant (that would reduce the net carbon benefit of the project)?
• Scalability and modularity: Does the technology afford a modular development and mass manufacturing approach that will expedite deployment and reduce costs due to learning curves?

Pillar 2: Commercial strategy

• Revenue model: Is there revenue via long-term, fixed-price offtake contracts for the CO2 captured or carbon removal credits? For DAC projects, it is critical to secure high-value CDR credit contracts (often >$600/tonne) in order to become profitable .
• Quality of customers: Who are the offtakers? Are they investment-grade companies with strong and committed decarbonization commitments, or are they more speculative buyers?
• Market positioning: Is the company a pure play technology provider, integrated project developer, or a specialized service provider (e.g., transportation and storage as a service)?

Pillar 3: Project execution & geology

• Management team: Does the leadership team have relevant experience in developing and delivering large and complex energy or industrial infrastructure projects?
• Storage security: For sequestration projects, how extensive has geological characterization of the proposed site been undertaken? Have leakage and/or induced seismicity risks been adequately addressed and mitigated ? The Gorgon project demonstrates the value of having contingency storage sites, which is a prudent strategy .
• Infrastructure & logistics: What is the plan for transport of the captured CO2? Is the project able to utilize existing pipeline infrastructure, or will it need to build its own?

Pillar 4: Policy & ESG

• Incentive optimization: Is the project structured to maximize eligibility for incentives (e.g., 45Q tax credit), including having met labor provisions to access the maximum amount of the tax credit .
• Permitting & social license: What is the status of all federal and state permits required for the project? Has the company undertaken good faith engagement with stakeholders to secure a social license to operate in the area?
• Lifecycle carbon accounting: What is the full lifecycle carbon footprint of the project? Having a credible, third-party verified lifecycle assessment (LCA) is a prerequisite for ESG credibility.

7.3 Financial modeling considerations

Analysts developing financial models for CCUS projects should pay specific attention to industry-specific drivers and risks. The model should be clearly specified to distinctly illustrate the project's three primary revenue and cost phases: construction, 12-year period for the 45Q credits, and operations post credits.

Some important inputs that should be modeled and sensitized include:* Capital Expenditures: Modeled on a dollar-per-tonne of annual capacity basis, with separate line items for capture equipment, compression, and any transport/storage infrastructure.

• Operating Expenditures: Operating costs should be detailed between fixed costs (labor, maintenance) and variable costs. The greatest attention should be paid to energy consumption, which in many cases, will be the largest singular OPEX item.
• Revenue Streams:
  • 45Q Tax Credits: Modeled for eligibility over the 12 years following commissioning. Analysts will need to accurately model the borrower's ability to utilize, as either the borrower has a sufficient tax appetite, elects direct pay for the first 5 years, or sells the credits in the transfer market .
  • Carbon Credit Sales: Voluntary or compliance carbon markets. This would necessitate explicit assumptions about future carbon prices.
  • CO2 Sales: For utilization projects, revenues sold as CO2 for EOR, concrete manufacturing, or other industrial usages.
• Recapture Risk: Models needing to model the recapture risk associated with taxpayers, having to pay back 45Q credits previously claimed, if it is found that the captured CO2 leaked .

7.4 Key due diligence priorities

Outside of the analytical framework, rigorous Due Diligence is essential. Key priorities for the investor should be to ensure:

• Technical Due Diligence: Engaging an independent engineering review to validate performance claims around the capture technology, energy consumption, and operational reliability.
• Geological Due Diligence: Any project that entails storage will need to engage independent third-party geological experts to review subsurface data to assess the capacity and integrity of the storage reservoir, and validate the monitoring, reporting, and verification (MRV) plan.
• Commercial Due Diligence: Review the terms of all offtake agreements or carbon credit sales agreements, including verifying price, tenor, volume committed, and counterparty creditworthiness.
• Regulatory & Permitting Due Diligence: Confirming the status of all required permits (e.g., EPA Class VI well permits for storage) and reviewing the public engagement record assessing the risk of any litigation or community opposition.
• Financial & Structural Due Diligence: Auditing the capital budget and financing plan associated with the project will be important for understanding the breadth of the tax equity structure, if applicable, and how the economic value will be shared across stakeholders.

7.5 A guide to patterns of recognition

As the carbon capture industry matures, we are establishing patterns of success and failure. Recognizing these patterns can help investors to identify successful projects and avoid failings that we now better understand.

Patterns of Successful Projects Often Include:

• Targeting High-Purity CO2: Early movers are identifying industrial processes that produce a high-purity stream of CO2 (e.g., ethanol production, natural gas processing), where capture costs are considerably lower (25/tonne), and well-established technologies.
• Hub & Spoke Models: The development of regional hubs common with industry energy projects, where shared pipeline transport and storage infrastructure exist that allows all emitters to share costs, creating economies of scale and de-risking the entire value chain.
• Strong Partnerships: Success developers have developed deep partnerships with industrial emitters, technology providers, and successful midstream companies that combine expertise and share risk.
• Vertical Integration: Companies that control multiple parts of the value chain can have better control of project timelines and economics.

Common Patterns of Failure, or Red Flags:

• Underestimating Geological Complexity: Gorgon project reminds that geological reservoirs can behave in ways we did not expect even with extensive studies. Projects that lack fully robust contingency plans or alternative sites will inherently carry greater risk [id_80].
• Ignoring social license: Projects that do not engage early, openly, and as transparently as possible face delays or public opposition that is costly and derail the project completely.
• Technology Overpromise: Companies that have aggressive, unproven claims surrounding cost, or performance, from a technology risk that is not supported by proven pilot-scale, or independent, are technologies to avoid.

8. What Drives Returns

Understanding what drives investment returns in the carbon capture sector takes a multi-dimensional view that goes beyond traditional financial analysis. This sector is emerging and relies heavily on external factors influencing sector performance and economics, thus it is important for investors to consider catalysts, leading indicators, common investment theses, and a robust list of risks. Success will be based on recognizing and tracking the indicators of growth, de-risking, and value creation across the CCUS chain.

8.1 Key catalysts and leading indicators

Catalysts are discrete events or developments that can materially change the trajectory of a company or industry. Leading indicators are observable data points that may indicate future performance.

Key Catalysts:

• Policy and regulation: Government action is perhaps the most powerful catalyst in this market. Even passing landmark legislation like the U.S. Inflation Reduction Act (IRA), which raised the 45Q tax credit massively, changed project economics overnight . Other policy level catalysts in play include formal carbon pricing (tax or trading schemes), speedier permitting for Class VI injection wells, and sufficiently mature carbon accounting and verification frameworks.
• Technological advances: Announcing material improvements in either capture efficiency or cost reduction is also an empowering catalyst. For instance, if a company announces work on a novel solvent that greatly reduces the energy penalty of capture, or if a DAC company achieves its cost-reduction targets sooner than anticipated, it could create an insurmountable competitive advantage. Climeworks example includes its G3 DAC technology development that halved their energy consumption and costs .
• Successful commissioning of flagship projects: Successful commissioning of first-of-a-kind (FOAK) or commercial projects is a totally critical de-risking event for the sector as a whole. Bring an operating project from a new industry (eg. cement) or utilizing unique technology that achieves its intended capacity and cost targets provides replicability and confidence to financiers and customers alike.
• Large-scale off-take agreements: Signing long-term, bankable carbon removal or CO2 off-take agreements with credible counterparties (ie. large corps with net-zero goals like Amazon) gives revenue certainty and is critical for project financing. A lot of such agreements indicate strong underlying demand for decarbonization.

Leading Indicators:

• Project pipeline growth: Number of projects, capacity, and diversity of projects in the development pipeline are a first-order indicator of industry health. Organizations like the Global CCS Institute (GCCSI) data show a constant progression of projects from early assessment to final investment decision (FID) indicates ongoing momentum. The pipeline is now over 700 projects in various stages of progress, which indicates strong interest .
• Capital investment flows: Tracking capital flows into the sector is paramount. This includes venture capital funding into tech startups, private equity funding into project developers, and non-recourse project level finance available for mature carbon capture assets. Growth in project financing in particular implies that the sector is maturing and its risk profile is becoming more palatable for conservative debt providers .
• Evolution of carbon price: For the projects dependent on carbon markets, the price of credits or allowances will be a direct driver of profitability. Increasing demand and prices for high-quality, permanent carbon credits in the voluntary market or compliance market pricing indicates a strong positive.
• Multi-user infrastructure: Progress on developing socialized CO2 pipelines and storage hubs is an enabling function of the sector overall. Announcements of new hub projects, successful open seasons for pipeline capacity, or approved storage sites signal the formation of geographic clusters which will minimize costs and barriers of entry for individual capture facilities.

8.2 Common investment theses

There are a variety of strategic rationale for investor engagement in the carbon capture sector, as each capital provider targets a different area in the value chain or has a different risk/return profile.

• The Technology Leader: The thesis here is to invest in companies that are developing and owning proprietary capture technologies (e.g., novel solvents, sorbents, membranes). The investment thesis is to back the future winner in the carbon capture market whose capture technology becomes the industry standard on account of significant cost and performance advantages, and in turn creates high-margin revenues-style impacts from licensing of the technology, resale of equipment, and other engineering services. This could be considered high-risk, high-reward, venture-style bets on true disruptive innovation.
• The Infrastructure Owner: The thesis here is to develop, own, and operate midstream and downstream assets (i.e. CO2 pipelines and geological storage assets). After development, both asset types can generate stable, predictable, utility-like returns to the infrastructure owner in line with long-term contracts. This investment strategy is generally attractive to infrastructure funds or investors seeking predictable cash flows with limited commodity risk or technology risk.
• The Integrated Project Developer: The thesis here is to invest in the project developer who runs the entire CCUS project lifecycle from sourcing the capture technology, securing the necessary permits, arranging financing, and running the operations. This is akin to a decarbonization-as-a-service provider, and by definition the value is captured across the entire value chain. The thesis is reliant on the developers' track record and sophistication and prowess to manage risk and structurally bankable projects for capital to flow.
• The Indispensable Enabler: Finally, a broader, top-down thesis is that CCUS is fundamentally compulsory for achieving the world's climate ambitions by 2050, with particular relevance to industrial emissions mitigation in hard-to-abate sectors such as cement and steel . If true, the long-term demand is virtually certain given global climate requirements, providing a durable tailwind across the entire sector. Investment will be made across the value chain with the belief that policy, demand, and the market, will overcome any short-term challenges.

8.3 An exhaustive list of risks - Carbon Capture and Storage

The carbon capture industry has a reasonable tailwind, but there are a substantial number of risks that investors need to thoughtfully analyze.

• Policy and Regulatory Risk: The economic factors that drive the industry are highly dependent on government incentives. The potential for policies to be altered, reduced or removed in the event of a political change is arguably the single biggest risk. For example, if the U.S. reverses the enhancements to the 45Q tax credits, numerous projects would be uneconomic . There are also risks related to the length, uncertainty, and complexity of permitting pipelines and storage wells that could lead to delays and cost overrun.
• Technological and Operational Risks: There is a substantial risk that projects will not behave as expected. Capture technologies may not meet their expected efficiency or commercial-scale cost reductions, and the reliability of operations may not be at anticipated levels . With storage, the singular risk is containment loss. The geological formation may turn out to be less suitable than initial estimates, leaving little or no capacity and unexpected fault lines could provide a pathway for CO2 . The potential for pipeline corrosion is another transportation risk .
• Economic and Financial Risks: CCUS projects have substantial upfront capital intensity, with individual projects typically exceeding a billion dollars. At such capital intensity, internal and external funding will be sensitive to interest rates and availability of capital. Revenue streams are also directly correlated to carbon prices or creditworthiness of offtakers. High operating costs for the energy necessary to capture CO2 are also a risk to margins .
• Infrastructure and Execution Risks: There continues to be a fundamental challenge related to CCUS project execution, often described as a "chicken-and-egg" scenario. Large-scale capture projects require transport and storage infrastructure to be economic, while a "chicken-and-egg" - i.e., building and delivering infrastructure to accommodate capture projects isn't feasible until there is a critical mass of capture projects. This coordination challenge creates significant execution risk. Finally, infrastructure projects are typically characterized as having development and execution overruns. * Public Acceptance and Social License Risk: Local community and environmental group opposition to pipelines and storage sites can derail projects. The concerns almost always are around safety (e.g., ruptured pipelines and leaking CO2), environmental justice, groundwater contamination, induced seismicity, etc., which is often referred to as a "social license to operate." The failure to engage with transparency and share project benefits creates a major non-technical risk .
• Reputational and Moral Hazard Risk: Investors face reputational risk from association with projects perceived as "greenwashing," or prolonging fossil fuel usage. The notion that CCUS is creating a moral hazard, taking focus away from renewable energy and efficiency investments is always discussed by critics and could change public and political opinions.

8.4 Framework for tracking risks and catalysts

Active portfolio management within the carbon capture domain requires a method for tracking the key variables that drive returns and risks. Investors should develop a dashboard for systematically monitoring policy, project development, technology costs and performance, carbon markets, keys to social license and investment portfolio exposure to address.

• Tracker for policy and regulatory developments: Keep a log of upcoming legislative votes, regulatory dockets (e.g., EPA Class VI well application status), and policy proposals in key jurisdictions. This will provide an early warning system for both positive and negative developments.
• Tracker for projects and investments: Use databases put out by others (e.g., Global CCS Institute) and financial market data providers to build a Big-Board to track global project pipelines, commercial FID announcements, and capital flows (VC, PE, project finance, etc.). For example, a slowdown in FIDs or decline in funding could be a leading indicator of their waning confidence in the CCUS sector.
• Log for technology costs and performance: Document public announcements from technology developers, as well as data from recently commissioned plants, on key performance indicators including: realized capture costs ($/tonne), energy consumption (GJ/tonne), and plant availability. This could be supportive or challenging for their cost-reduction assumptions.
• Dashboard for carbon markets: Track daily and forward prices for relevant carbon credits (e.g. VCM nature-based credits vs. engineered and removal credits) and compliance market allowances (e.g., EUAs, CCAs). Also, the price spread between different carbon credits could be another signal related to changing preferences of buyers.
• Sentinel for social license: Keep track of media articles, NGO reports, community meetings on major projects to gauge levels of public support and opposition. For example, delays in local permitting hearings could be a red flag related to escalating opposition.

By tracking multiple indicators in a cross referenced manner, investors can conduct dynamic scenario analysis, adjust portfolio exposure, and make more informed investment decisions in a rapidly changing and fluid industry.

9. Further Reading

For investment professionals who want to further develop their understanding of the carbon capture sector, there are a limited number of organizations, publications, and events for tracking industry, and its associated trends, policy changes and technology advancements.

In particular, a small number of non-profits, government and intergovernmental entities provide the most credible data and analyses on the CCUS sector.

• Global CCS Institute: This international think tank is arguably the most important single resource for sector-wide data as it publishes an annual report "Global Status of CCS" which provides a comprehensive overview of the project pipeline status and journey from early development to operations, which is female role model for tracking sector base and growth.
• International Energy Agency (IEA): IEA provides deep-dive analyses and long-term scenarios on the role of CCUS in their worldwide energy and climate outlooks. Their reports provide authoritative perspectives on technology readiness, policy effectiveness, and CCUS in the overall energy system . The IEA's modeling results are frequently referenced in national energy plans and strategies.* U.S. Department of Energy (DOE) and National Energy Technology Laboratory (NETL): If you focus on the U.S. market, the DOE is your top source. The DOE is the primary source of federal research, development, and demonstration funding. Their national laboratory, NETL, is the host of public work developing rigorous cost performance baselines for power and industrial capture, as well as roadmaps to target cost in the technology .
• Carbon Capture Coalition: This makes up a bipartisan coalition of more than 100 companies, unions, and NGOs, and is the most significant advocate of federal CCUS policy in the United States. Reading their publications and following their policy recommendations will give insight into the legislative agenda and stakeholder consensus in the world's largest CCUS investment market.
• Clean Air Task Force (CATF): CATF is a nonprofit environmental research and advocacy organization that conducts in-depth analysis regarding decarbonization technologies, including CCUS. The organization implements policy work grounded in rigorous reports and interactive maps that track the CCUS project development timeline and potential location of CO2 storage, which have rigor and policy action implications that have value.

9.2 Suggestions for further reading

Beyond following the routine publications from the associations mentioned above, there are a few reports, and academic journals, that will help you dive deeper into a subject.

• Global Status of CCS (Global CCS Institute): This annual report is required reading for any investor who is reading this. It provides the most current data on number of facilities, capture capacity, and progress globally, and is informative to take a "snapshot" of momentum in the industry.
• Energy Transition Outlook (DNV): The risk management and quality assurance firm DNV publishes an annual forecast based on an independent model of the world's energy system. DNV's projections for the deployment of CCUS, investment, and cost reductions are valuable to provide a real third-party perspective on the long-term trajectory of the sector .
• IEA Special Reports on CCUS: IEA publishes special reports, such as "CCUS in Clean Energy Transitions," and "The Role of CCUS in Low-Carbon Power Systems," that provide an extensive analysis that covers foundational knowledge and significant detail to understand the strategic role of this technology.
• International Journal of Greenhouse Gas Control: For those of you who want to delve into the technical challenges and details beyond what I cover in this primer, this peer-reviewed academic journal is the leading publication. It continues to publish groundbreaking research on all aspects of CCS, from new capture materials to long-term storage monitoring.

9.3 Major industry events and conferences

Industry conferences are important venues, both for passive networking, hearing directly from a company's management, and experiencing first-hand the latest commercial and technology developments.

• GHGT (Greenhouse Gas Control Technologies) Conference: This is a premier scientific conference, hosted every other year, on CCUS, which brings together academics, researchers, and industry professionals to discuss the latest advancements in science.
• Carbon Capture Technology Expo & Conference (North America and Europe): The largest industry-centric commercial events, with large exhibition promotions, and multiple tracks from policy and finance to new capture technology and infrastructure projects.
• CO2 Conference: The CO2 conference (the long history was rooted in Enhanced Oil Recovery (EOR), the conference is often now called the CO2 & Carbon Management Workshop), has maintained a focus on a wider collection of CCUS applications, and serves as one of the foundational gatherings of professionals in the storage and utilization space.
• World Carbon Summit: This event is mainly focused on the carbon market, but there were dedicated sessions, and a strong attendance by the CCUS community in recent years. The World Carbon Summit serves as a good venue for understanding the fit of carbon capture technology into the world of carbon credits and offsets across corporate decarbonization strategies.

9.4 Glossary with abbreviation cross-reference

The carbon capture space is filled with technical acronyms and nomenclature. Each primer, and other literature in the field, will require a glossary to help you navigate the landscape. This primer has a glossary with comprehensive cross-medium of the terms used to facilitate reader understanding.

10. Conclusion

The carbon capture, utilization, and storage industry is at a pivotal inflection point, evolving from a niche technology used almost exclusively for enhanced oil recovery to a new standard that is critical in attaining global climate targets. For investment professionals, it provides one of the most exciting, and yet complicated, long-term growth opportunities in the energy transition space. The investment case is not built off of wishful thinking, but rather a rational understanding that decarbonizing heavy industry and removing legacy CO2 from the atmosphere are unavoidable tasks where CCUS will be an indispensable tool .

This primer has shown that the sector's recent momentum is being facilitated by powerful policy tailwinds, most notably the U.S. Inflation Reduction Act which has essentially changed project economics and spurred an influx of investment . Global capital committed to CCUS will continue to grow tremendously, and forecasts estimate cumulative investment could approach $80 billion by 2030 . This capital will find its way into a diverse ecosystem of companies, from innovative technology developers of next generation capture materials to infrastructure champions building the pipelines and storage hubs that will underpin a new low-carbon industry.

Nevertheless, the journey to gigatonne-scale deployment will not come without serious headwinds. As expressed, investors will need to navigate an ecosystem with high capital intensity, sizable policy risk, long project development timelines, and emerging technology risk . The operational challenges of scaling first-of-a-kind projects, logistical hurdles of building next generation infrastructure networks, and the need to build and retain public trust for geological storage will create substantial commercial risks requiring serious due diligence and active management  .

Success in this emerging field will require moving beyond traditional investment frameworks. It will require sophistication and a firm understanding of the duality of policy, technology, and markets. Investors who will be able to successfully target opportunities will be those who can discern technology readiness, model ongoing regulatory incentives, and distinguish business models with sustainable competitive advantages; those that will be able to find leading indicators of growth and differentiate credible business plans from overly ambitious plans will succeed.

Carbon capture is more than just an environmental technology; it is a developing industrial sector with a unique value chain, unique business models, and unique return drivers. The opportunity is huge as there is a structural need for decarbonization solutions to reach climactic targets for sectors like cement, steel, and chemicals, and to provide the necessary carbon removal that is needed for a balanced global carbon budget. For investors that are equipped with the analytical frameworks and strategic lens introduced in this primer, the carbon capture industry provides a unique opportunity to deploy capital as a critical climate solution while progressing significant long-term financial returns. The journey will be long and complicated, but for those familiar with the landscape, the potential rewards - both financial and environmental - will be considerable.
