What is the real market size of CCUS?
Building a startup or looking for your next investment in CCUS? Our report gives you the full picture.
Summary
The real CCUS market is roughly $5 billion to $6 billion a year today, with about $4 billion to $8 billion as a reasonable wider range depending on how much capture, transport, storage and utilization activity is included.
The apparent disagreement between market studies is mostly a scope problem. Using the same 2025 base year, public estimates run from $3.2 billion to $5.82 billion, an 82% gap before broader infrastructure definitions are added.
The strongest cross-check is that commercial market estimates and actual project investment are landing in the same order of magnitude. The IEA says annual CCUS investment exceeded $5 billion in 2025, which is not the same thing as supplier revenue but does support the idea that the current industry is still a single-digit-billion-dollar market.
The physical market is also much smaller than the project headlines suggest. Around 50 to 65 Mt of annual capture capacity is operating today, while roughly 108 Mt is either operating or already under construction.
The often-cited 425 Mt project pipeline is real as a statement of developer ambition, but weak as a measure of today's market. Around 90% of announced projects targeting operation by 2035 still await final investment decision.
The next wave of CCUS is likely to be more expensive per tonne than the old one. Natural gas processing has dominated historical deployment because the CO₂ stream is relatively easy to separate; cement, steel, power and refining generally require much more costly capture systems.
That means revenue and investment could rise faster than captured tonnes. Doubling physical capacity does not necessarily mean doubling the dollar market if the additional projects sit in harder, more capital-intensive sectors.
Shared transport and storage hubs are starting to change the structure of the business. Northern Lights, Porthos and the first UK clusters show how CCUS can move from one-off industrial projects toward network infrastructure serving multiple emitters.
Private capital is entering, but mostly where governments have already reduced the hardest risks. More than $15 billion of commercial debt was raised over two years, yet the UK alone accounted for around 85% of the debt identified by the IEA.
The biggest distinction is between the market that exists and the infrastructure opportunity that could exist. A move toward $10 billion or $20 billion of annual spending is increasingly plausible from the committed construction pipeline; $40 billion requires many more announced projects to reach FID, and hundreds of billions belong to a much longer-term buildout story.
So CCUS is no longer a tiny demonstration niche, but it is still early. The industry has crossed into serious infrastructure deployment without coming anywhere close to the scale implied by its full project pipeline or by long-term decarbonization scenarios.

In our report covering the carbon capture market, we always try to gather several sources and make estimates that make sense, so you can work with solid numbers.
Why do CCUS market estimates range from $3 billion to almost $6 billion?
CCUS market estimates vary so much because researchers are counting different parts of the industry.
We checked several of the latest public estimates using the same 2025 base year. IMARC puts the carbon capture and storage market at $3.2 billion. Grand View Research gives $3.9 billion. Stratview Research estimates $5.1 billion. Precision Business Insights gives $5.46 billion. MarketsandMarkets reaches $5.82 billion.
That is already an 82% gap between the lowest and highest estimates, before getting into even broader definitions that include more infrastructure or CO₂ utilization.
The scope explains most of it. Some studies focus heavily on capture technology and equipment. Others include transportation, utilization and storage services. Some measure revenue generated across the supply chain, while infrastructure spending can be measured separately as investment.
There is also a surprisingly important question around what counts as “utilization.” The IEA's current CCUS project database excludes conventional uses with weak climate benefits, such as food and beverages, internal CO₂ use in urea production and naturally occurring CO₂ used for enhanced oil recovery. Including those activities would make CCUS look much larger without telling us much about the new decarbonization industry.
For this analysis, we use the market created by capturing, transporting, storing and climate-relevantly using CO₂. That gives us a cleaner view of the business actually being built around CCUS today.
| Source | 2025 market estimate | Main scope |
|---|---|---|
| IMARC | $3.2B | CCS |
| Grand View Research | $3.9B | CCS |
| Stratview Research | $5.1B | CCUS |
| Precision Business Insights | $5.46B | CCUS |
| MarketsandMarkets | $5.82B | CCUS |
| Median of these estimates | $5.1B | Mixed definitions |
So how big is the CCUS market in dollars today?
The best working estimate for the CCUS market today is roughly $5 billion to $6 billion a year.
That range sits near the middle of the latest commercial market estimates, and we get an unusually useful cross-check from the IEA.
The IEA says global investment in CCUS projects exceeded $5 billion in 2025. Annual investment and supplier revenue measure different things, so we should avoid treating them as interchangeable. Their convergence around the same order of magnitude still gives us confidence that today's industry is measured in single-digit billions of dollars.
A broader $4 billion to $8 billion range is defensible if someone uses a wider or narrower definition of capture equipment, engineering, transportation, storage and utilization.
Anything vastly above that starts describing future infrastructure, cumulative project value or theoretical demand rather than the CCUS market companies are actually serving today.

In our research about carbon capture, we don't want to repeat what boring consulting reports say. Instead, we show you the real and latest market signals that matter.
How much real money is going into CCUS projects now?
Money going into CCUS has accelerated dramatically, with annual investment now above $5 billion after growing more than fifteenfold since 2020.
The latest IEA financing review gives us one of the clearest signs that CCUS has moved beyond the very small demonstration market of a few years ago. More than 30 projects reached final investment decision over the previous two years, covering transport and storage infrastructure, industry and power.
More than $15 billion of commercial debt was also raised during those two years.
The trajectory is more revealing than the absolute number. Fifteenfold growth from 2020 means annual investment was still only in the low hundreds of millions of dollars around the start of the decade. CCUS has crossed into a different financial scale very quickly.
There is still heavy concentration, though. Large European and North American projects account for much of the capital. A relatively small number of billion-dollar developments can move the worldwide investment figure materially.
So we are seeing real acceleration, but we are still looking at an infrastructure market where dozens of large projects matter more than thousands of small customers.
How much CO₂ is CCUS actually handling today?
CCUS currently has only around 50 to 65 million tonnes of annual operating capture capacity worldwide.
The range comes from different project databases and inclusion rules. The Global CCS Institute counted 77 operating commercial CCS projects with about 64 Mt of annual capture capacity in its latest full status report. The IEA uses stricter filters and has reported a somewhat lower operating base.
The Global CCS Institute also counted 47 projects under construction representing another 44 Mt per year. If those facilities all start operating, the visible physical market rises from 64 Mt to roughly 108 Mt, an increase of almost 70%.
That is meaningful growth.
It is also tiny compared with the emissions base CCUS could theoretically address. The IEA says global energy-related CO₂ emissions reached almost 38.4 billion tonnes in 2025. Sixty-four million tonnes of operating capture capacity equals about 0.17% of that amount.
CCUS has become a real industrial activity, but its current physical footprint is still very small.
Can we really trust the 425 Mt CCUS project pipeline?
The 425 Mt CCUS pipeline shows genuine demand, but most of it is still too early to count as a real market.
The latest IEA project update keeps potential future capture capacity at roughly 425 Mt per year. That is around seven times the operating base measured by the Global CCS Institute.
The problem appears when we look at project maturity. Around 90% of announced CCUS projects targeting operation by 2035 still await final investment decision, according to the IEA's latest financing work.
Timelines have also slipped. The total pipeline barely changed in the latest annual update, while a significant share of expected commissioning moved further toward 2035 because of permitting, construction and commercial delays.
Porthos gives us a good real-world example. Construction on the Dutch CO₂ transport and storage network is well advanced, with pipelines laid and injection wells converted, yet the planned start moved from 2026 to the second half of 2027 after different parts of the project took longer than expected.
The 425 Mt figure tells us that developers want to build a much larger industry. It tells us much less about how much capacity will actually be operating in the next few years.

In our market report about carbon capture, we like to show you the big picture. We know your time is precious, so we make every page quick to read and packed with as much learning as possible per minute.
Which industries really make up the CCUS market today?
Natural gas processing still dominates existing CCUS capacity, while cement and other harder industries are only starting to become meaningful.
The IEA found that more than 60% of operational capture capacity was attached to natural gas processing facilities in its previous project review.
There is a simple economic reason. Natural gas processing often produces highly concentrated CO₂ streams, making separation much easier and cheaper than pulling CO₂ out of dilute cement, steel or power-plant exhaust.
The interesting change is happening at the edge of that old market.
Heidelberg Materials' Brevik plant in Norway became the world's first industrial-scale carbon capture facility at a cement plant. Its latest company reporting shows that 58,408 tonnes of CO₂ were transferred to Northern Lights during 2025, with 37,500 tonnes already permanently stored below the North Sea by year-end.
That is still tiny beside the facility's eventual design capacity of roughly 400,000 tonnes per year, but it gives us something much more useful than another announcement: actual tonnes moving through a new cement-to-storage value chain.
Heidelberg Materials is also building its Padeswood capture facility in the UK, with construction reported on schedule during 2026.
The next phase of the CCUS market will look quite different from the historical one. Cement, power, waste, hydrogen and carbon removals are gradually joining an industry that was built mainly around easier CO₂ streams.
Why can capturing one tonne of CO₂ cost $20 or $160?
CCUS economics change completely depending on where the CO₂ comes from.
A concentrated CO₂ stream can require relatively little separation work. A dilute exhaust stream needs much larger equipment, more heat and more energy.
The U.S. Department of Energy's latest commercial-liftoff work puts capture from some high-purity streams such as natural gas processing and ethanol below roughly $30 per tonne in favorable cases. Cement, steel, refineries and power plants commonly land much higher, with indicative ranges that can move above $100 per tonne before adding all transport and storage costs.
That creates an unusual feature in the CCUS market: moving from 50 Mt to 100 Mt of capture does not necessarily mean the dollar market merely doubles. If the additional tonnes come increasingly from cement, steel and power, every tonne can require considerably more capital.
This is one reason future CCUS spending could grow much faster than physical capture capacity.
| Application | Indicative capture economics |
|---|---|
| Natural gas processing | Among the cheapest, sometimes below $20-30/t |
| Ethanol | Often below $30/t |
| Concentrated hydrogen streams | Around $50/t and above |
| Cement | Often roughly $70-120/t before full-chain costs |
| Steel | Commonly around $75-120/t |
| Coal power | Roughly $75-120/t |
| Refining | Often around $85-120/t |
| Gas power | Can exceed $80-130/t |
| Direct air capture | Can extend into several hundred dollars per tonne |

Does CO₂ utilization make the CCUS market much bigger?
CO₂ utilization makes the headline volume look much bigger, but most existing CO₂ use belongs outside the emerging CCUS decarbonization market.
Around 230 Mt of CO₂ are used globally each year according to the IEA's long-running estimate. Fertilizer production accounts for roughly 130 Mt, while enhanced oil recovery consumes around another 70 to 80 Mt.
That is several times today's dedicated capture capacity.
Yet much of this activity existed long before the current CCUS buildout. Urea plants can use CO₂ generated within their own conventional process. Enhanced oil recovery has historically used both captured and naturally occurring CO₂. Food, beverage and greenhouse applications also provide little indication of demand for permanent carbon management.
The IEA therefore excludes several of these conventional pathways from its current CCUS project database.
New utilization markets such as synthetic fuels, chemicals and mineralized building materials are more relevant, but they remain much smaller today.
For market sizing, adding the entire 230 Mt CO₂-use industry would make the CCUS number look impressive while making the answer less useful.
If you want more recent data on this point, please see our latest CCUS market report.
Where is the CCUS market actually growing now?
Europe, North America, China and the Middle East are driving most of the serious CCUS buildout today.
The regional pattern has shifted slightly over the past few years.
North America still has the deepest operating history, helped by natural gas processing, ethanol, fertilizer, CO₂ pipelines and enhanced oil recovery. U.S. tax credits have also created a much stronger project pipeline.
Europe has become the clearest test of the shared-infrastructure model. Northern Lights is now operating in Norway, Porthos is under construction in the Netherlands, and the UK has taken its first large clusters through financial close.
China and the Middle East are becoming harder to ignore. The IEA has previously counted more than 15 Mt of capacity under construction across those two regions, and its latest database update says Europe and the Middle East recorded particularly strong gains during 2025.
The UK is also expanding beyond its original projects. HyNet's first transport and storage network reached financial close, further emitter projects have entered negotiations, and the government's latest major-project documents show continued work on cluster expansion.
CCUS is becoming geographically broader, although the market still grows fastest where governments have created clear rules, storage access and a way for projects to earn money.
Our report covering the carbon capture market gets updated several times a month, so you always get the latest view of where things stand.
Could CO₂ storage become the biggest CCUS bottleneck?
Ready-to-use CO₂ storage is becoming more important than the amount of geology underground.
The world has enormous theoretical geological storage potential. The commercial problem is developing individual reservoirs into permitted, characterized and financed storage sites that customers can actually use.
That requires seismic surveys, appraisal wells, injection permits, monitoring systems, pipelines or ships, liability arrangements and long-term contracts.
The latest IEA project update is revealing here. Storage capacity that was operating or under construction grew by around 25% year over year, faster than the increase in capture capacity. That sounds positive, but the IEA is now watching for the opposite problem: some storage developers could end up with too little committed CO₂ if capture projects continue slipping.
Equinor has already scaled back parts of its storage investment plans for this reason.
So storage has two possible bottlenecks. Too little capacity can block capture projects, while building storage too early leaves expensive infrastructure underused.
The CCUS market increasingly depends on getting those two sides to grow at roughly the same speed.
Are shared CCUS hubs actually changing the economics?
Shared CCUS hubs are making the industry much easier to scale because one transport and storage system can serve several emitters.
Northern Lights is the clearest operating example.
Its first phase provides 1.5 Mt of annual storage capacity. Equinor, Shell and TotalEnergies have committed NOK 7.5 billion to phase two, taking total injection capacity to at least 5 Mt per year. The expansion followed a 15-year agreement with Stockholm Exergi covering up to 900,000 tonnes of CO₂ annually.
Porthos follows the same logic in Rotterdam. The project will initially transport and store roughly 2.5 Mt per year from industrial customers, while its infrastructure has been designed with room for future expansion.
The UK is building entire regional systems around the same idea. East Coast Cluster and HyNet combine capture projects with shared pipelines and offshore storage rather than asking every factory to build a complete CO₂ chain on its own.
That changes what the CCUS business can become. Transport and storage start behaving more like infrastructure networks, where additional customers can connect to assets that already exist.
It also explains the enormous upfront costs. A hub can absorb billions before reaching full utilization, but each new customer can improve the economics of infrastructure already in the ground.
In our research about carbon capture, you will always find fresh funding data, taken straight from our own verified funding database.
Is private money really funding CCUS now?
Private finance is entering CCUS at scale, but governments are still doing much of the work that makes those investments possible.
The IEA says commercial lenders provided more than $15 billion of debt to CCUS projects over two years.
Nearly all of that lending appeared in markets where governments had already reduced major risks. The UK alone accounted for around 85% of the commercial debt identified by the IEA over that period.
That concentration tells us a lot.
The UK combines long-term contracts, revenue support, cross-chain protection and government backing for some risks. It has committed up to £21.7 billion over 25 years to launch its first CCUS clusters, alongside billions of pounds of private investment.
Norway heavily supported the first Northern Lights phase. European projects also use EU funding, carbon prices and contracts for difference. In North America, tax credits can turn low-cost capture projects into bankable businesses.
The commercial finance is real. The standalone economics remain immature.
We can see that in places where support is weaker or project risks remain messy. In Denmark, the IEA says 80% of industrial bidders withdrew from a recent CCUS auction after they could not make the cross-chain risks work. Hydrogen-linked capture and BECCS projects have also been delayed or cancelled after struggling to secure long-term customers.
For now, CCUS private capital follows public risk reduction very closely.
If you want more recent data on this point, please see our latest CCUS market report.
Could CCUS become a $40 billion market soon?
Annual CCUS spending could eventually move into the tens of billions, but $40 billion is still an upside buildout scenario rather than the current run rate.
Earlier IEA analysis showed that annual investment could exceed $40 billion if approved and announced projects progressed on their original schedules.
The newer evidence has made those schedules look aggressive.
The total announced capture pipeline remains huge, yet project dates have slipped and roughly nine out of ten announced projects still await FID. Several hydrogen, BECCS, power and industrial projects have also been paused or cancelled.
At the same time, construction-stage capacity is large enough to support substantial growth from today's spending level. The Global CCS Institute counts 44 Mt per year under construction, while the IEA expects the existing construction pipeline to nearly double operational capture capacity by 2030.
Moving from a roughly $5 billion annual investment market toward $10 billion or $20 billion therefore looks much easier to imagine than it did a few years ago.
Getting to $40 billion quickly would require many projects to cross FID almost together. The pipeline can support that scale. Current execution still cannot.
In our market report about carbon capture, we look at what the winners do differently, so you can learn from the best instead of guessing.
How big is the committed CCUS market compared with the headline pipeline?
The committed CCUS market is around 100 Mt per year of operating and construction-stage capacity, far below the 400-500 Mt figures often used to describe the sector.
This is probably the most useful way to understand the gap between today's industry and its advertised future.
The Global CCS Institute counts about 64 Mt per year operating and another 44 Mt under construction. Together, that gives roughly 108 Mt of capacity with physical assets already running or being built.
The IEA's broader announced pipeline is around 425 Mt. The Global CCS Institute's wider project universe reaches above 500 Mt because its definitions and project set differ.
As seen above, around 90% of announced projects still await final investment decision. That puts a large credibility gap between 108 Mt of operating or construction-stage capacity and the several hundred million tonnes regularly presented as the future market.
The gap does not make the pipeline meaningless. It tells us how much demand could emerge if financing, permitting and customer contracts fall into place.
For market sizing today, we would give far more weight to the first two rows.
| Layer of the CCUS market | Approximate annual capture capacity | How seriously we should count it today |
|---|---|---|
| Operating projects | ~64 Mt | Real market |
| Projects under construction | ~44 Mt | Highly credible near-term market |
| Operating + construction | ~108 Mt | Best view of committed physical market |
| IEA announced pipeline | ~425 Mt | Potential market |
| Broader project databases | 500+ Mt | Potential market with wider definitions |
| Global energy-related CO₂ emissions | ~38,400 Mt | Theoretical emissions base |
Is CCUS anywhere close to gigatonne scale?
CCUS is still roughly one order of magnitude away from the gigatonne scale usually associated with a major role in global decarbonization.
Today's operating base is around 50 to 65 Mt per year. Even the roughly 108 Mt of operating plus construction-stage capacity remains only around one-tenth of a gigatonne.
The IEA's Net Zero pathway has historically required total annual capture to exceed 1 billion tonnes around 2030. The exact pathway can change as energy scenarios change, but the size of the gap is unmistakable.
Even the entire current 425 Mt IEA project pipeline would leave the industry well below one gigatonne.
That is also why the long-term financial opportunity can become so much larger than today's $5 billion market.
A tenfold or twentyfold physical expansion would require thousands of pieces of capture equipment, new compression facilities, pipelines, ships, terminals, wells and monitoring systems. Many of the future tonnes would also come from more expensive sectors than today's natural gas processing-heavy installed base.
CCUS has enormous room to grow simply because its starting point is so small.
If you build or invest in the carbon capture market, you need to know which business models pay off now and which ones are fading. That's why our report covering it has a whole section on it.
So what is the real market size of CCUS today?
The real CCUS market today is roughly $5 billion to $6 billion a year, with about $4 billion to $8 billion as a reasonable range depending on what parts of the value chain are included.
We reach that conclusion from several independent angles.
The latest commercial market studies cluster around roughly $3 billion to $6 billion, with the middle of the group around $5 billion. As seen above, the IEA separately measured more than $5 billion of actual CCUS investment in 2025. The physical market supporting that spending is still only around 50 to 65 Mt of operating capture capacity.
The next market is already visible. Another 44 Mt per year is under construction, more than 30 projects reached FID over two years, shared CO₂ networks are starting to operate, and commercial lenders have put more than $15 billion of debt into projects.
Then comes the much bigger speculative layer. The IEA tracks roughly 425 Mt of announced capacity, but project delays and the huge share still awaiting FID make that a poor measure of today's market.
Our judgment is quite sharp: CCUS is currently a small, single-digit-billion-dollar global industry entering the first serious infrastructure buildout of its history. A market worth tens of billions of dollars a year is credible if construction keeps spreading beyond today's handful of leading regions. Hundreds of billions describe the longer-term infrastructure opportunity, not the business that exists today.

Our methodology
This analysis tests one simple question: what is the real market size of CCUS today? We treated it as an evidence-aggregation problem because commercial market studies use different scopes, project databases mix operating assets with early-stage announcements, and infrastructure investment can easily be confused with industry revenue.
We broke the question into the dimensions that most directly reveal current scale: commercial market estimates, annual investment, operating and construction-stage capacity, project maturity, capture economics, transport and storage infrastructure, financing activity, and actual project execution.
For each dimension, we prioritized the freshest observable evidence available, especially first-hand project disclosures, government material and institutions that maintain dedicated CCUS datasets. Commercial market studies were used to establish the range of published revenue estimates; investment data provided a separate financial cross-check; physical capacity showed how much infrastructure actually exists; and construction, FID and operating status helped separate committed activity from the much larger announced pipeline.
We kept different types of evidence in their proper roles. Annual investment is not treated as identical to industry revenue, announced capacity is not treated as equivalent to an operating market, and long-term emissions volumes or net-zero scenarios are used to show potential runway rather than inflate today's market size.
Where authoritative datasets use different project definitions, we retained those differences instead of forcing them into a single artificial number. The final estimate therefore comes from convergence across several independent signals, with the greatest weight placed on money already being spent, assets already operating or under construction, financing already committed and projects that have crossed meaningful development milestones.
The main market-size references include IMARC, Grand View Research, Stratview Research, Precision Business Insights, and MarketsandMarkets.
For project activity and physical deployment, the core references are the IEA CCUS Projects Database, IEA Financing CCUS at Scale, the IEA's latest CCUS project update, and the Global CCS Institute's Global Status of CCS 2025.
Capture-cost ranges come from the U.S. Department of Energy's Pathways to Commercial Liftoff: Carbon Management. CO₂ utilization volumes come from the IEA's Putting CO₂ to Use, while the comparison with global energy-related emissions uses the IEA Global Energy Review 2026.
We also used first-hand project disclosures to check whether announced activity is translating into physical infrastructure: Equinor on Northern Lights Phase 2, TotalEnergies on the Northern Lights expansion, Porthos on its revised project schedule, Heidelberg Materials' 2025 annual and sustainability report, Heidelberg Materials' Q2 2026 update, and the UK government's CCUS collection.
The result is deliberately anchored to the market that can be supported by several kinds of evidence at once, rather than the largest available forecast. Earlier-stage announcements still matter, but mainly as evidence of future potential.
When you build or invest in the carbon capture market, you need clarity, not confusion. In our report covering the carbon capture market, we always try to put numbers on and quantify whatever is usually vague and confusing.
