Europe’s CO2 storage story is getting bigger fast.
On paper, the region now shows a substantial portfolio of storage capacity under development. But when you look more closely at project maturity, a more nuanced picture appears: only a relatively small share is far enough along to be considered materially de-risked.
That is exactly why CaptureMap’s new transport and storage features matter. They make it easier to see not just where capacity exists, but where it sits in the development journey — from early feasibility to EPC to operation — and how that translates into realistic timelines.
The headline number is hard to ignore: 18.7 Mtpa of annual CO2 injection capacity is currently past FID, while 351 Mtpa remains pre-FID and may require considerable time to come into operation.
That contrast tells an important story. Europe is building momentum, but the majority of the storage portfolio is still a future market, not a fully deliverable one.
The real question is no longer just where storage is planned — it is when that storage is likely to become available.
High-level summary
- Europe has a large and growing CO2 storage projects portfolio, but most of it is still early-stage.
- Only 18.7 Mtpa is currently past FID, while 351 Mtpa remains in pre-FID phases.
- The UK, Norway, Denmark, and the Netherlands stand out as major storage markets by planned capacity.
- Country-level timelines show that capacity ramps significantly over the 2030s, not all at once.
Why storage maturity matters more than headline capacity
Big storage numbers can look impressive, but they do not all mean the same thing. A project in operation is very different from one in EPC, and both are very different from one still in feasibility. For anyone trying to understand when capacity may actually become available, that distinction matters.
That is where structured market intelligence makes the difference. Using CaptureMap’s transport and storage features, we can see not just how much storage is being announced, but where projects are being developed across Europe and how far they have progressed. The map below helps bring that picture into focus, showing the geographic spread of Europe’s storage portfolio, while our categorization adds the maturity context needed to separate near-term capacity from longer-term potential.
This analysis is based on CaptureMap’s standardized categorization of European CO2 storage projects by location, annual injection capacity, timeline, and engineering stage. As project maturity evolves over time, this should be read as a snapshot of the market at the date of publication.
Europe’s storage timeline shows growth — but not instant availability
The illustration below shows how annual operational injection capacity builds over time across European countries.
What stands out immediately is that growth is not evenly distributed. A handful of countries account for most of the visible ramp-up, with the UK leading the way, followed by Denmark, Norway, and the Netherlands. These markets are doing much of the heavy lifting in Europe’s near- and medium-term storage outlook. We don’t think it’s a coincidence that most of these countries around the North Sea basin are also highly experienced in oil and gas exploration and production. Many of them have regulatory regimes that are used to handling similar types of projects.
The chart also highlights another important point: capacity does not arrive as a smooth, continuous build. It comes in steps. That matters because storage availability is shaped by specific project milestones, regulatory progress, investment decisions, and infrastructure readiness. In practice, this means Europe’s storage market is likely to develop in waves, not in a straight line.
That said, we believe the large jumps in 2030, 2035 and 2040 are more ceremonial than actual reflections of financial or technical restrictions. In practice, we expect storage increases to be more rolling hills than jagged mountain peaks.
The project portfolio for storage is large — but mostly still in feasibility
The illustration below breaks down storage capacity by country and engineering stage: operation, EPC, and feasibility.
This is where the market’s maturity gap becomes especially clear.
Across Europe, the majority of capacity still sits in feasibility, not in construction-ready or operational phases. In other words, the storage project portfolio is considerable, but much of it is still subject to technical, commercial, regulatory, and financial uncertainty.
The country ranking is also revealing. Looking at total capacity, the UK leads by a wide margin with 142.5 Mtpa in the portfolio, followed by Norway (75.2 Mtpa), Denmark (68.1 Mtpa), and the Netherlands (41.0 Mtpa). After that, the projects becomes more fragmented across smaller national markets.
That does not mean smaller markets are unimportant. But it does suggest that, today, Europe’s storage outlook is still concentrated in a limited number of countries.
Article 23 of the NZIA raises the stakes
This picture matters not just from a market perspective, but from a policy one too.
Under Article 23 of the Net-Zero Industry Act (NZIA), the EU set a target of reaching at least 50 million tonnes of annual CO2 injection capacity by 2030. The framework is designed to turn storage from a long-term ambition into a concrete delivery obligation, and the Commission has since specified the pro rata contributions expected from obligated oil and gas producers.
That makes many of the countries in these charts especially important.
The countries already leading Europe’s storage project portfolio — particularly those with the largest and most advanced project portfolios — are likely to be pivotal in helping the region meet Article 23 obligations. In that sense, these projects are not just commercially interesting; they are central to whether Europe can translate regulatory ambition into real storage availability. Note that at the moment, UK and Norway are not part of these obligations. Although Bellona and others have started to wonder if Norway may have to be included afterall.

What the numbers really say
Metric | What it tells us |
18.7 Mtpa past FID | A meaningful base of more advanced storage capacity is emerging |
351 Mtpa pre-FID | Most of the market is still early-stage and likely to take time to materialize |
UK, Norway, Denmark, Netherlands lead | Storage readiness is concentrated in a few core countries, particularly around the North Sea basin. But Southern Europe is up and coming. |
2030s ramp-up | Much of Europe’s expected storage availability is still ahead, not fully here yet |
The gap between 18.7 Mtpa past FID and 351 Mtpa pre-FID is especially important. It shows that Europe has moved beyond pure concept-stage optimism, but it also shows that most of the expected market is still dependent on successful execution over many years.This is a marathon, not a sprint.
For anyone using CO2 storage assumptions in market planning, that distinction is crucial.
Key takeaways
Europe’s CO2 storage market is clearly gaining depth. The portfolio is getting larger, the country base is widening, and the 2030s point to substantial future capacity growth.
But the data also shows something equally important: most of that growth is still not fully de-risked.
With 18.7 Mtpa past FID and 351 Mtpa still pre-FID, the market is best understood as a space with strong momentum, but also a long road from project portfolio to operation. That is precisely why structured, standardized market intelligence matters. It helps separate what is operational, what is advancing, and what may still take years to materialize.
What’s next? These storage projects need something to connect to – the missing link between capture and storage. And that’s: transport. Stay tuned for an upcoming article about this.

Definitions
CO2 storage project: A project designed to inject and permanently store captured carbon dioxide in geological formations.
Injection capacity (Mtpa): The amount of CO2 that can be injected and stored each year, measured in million tonnes per annum.
FID (Final Investment Decision): The point at which project sponsors formally commit capital to move forward with development.
Pre-FID: Earlier project phases before final investment commitment, often including screening, feasibility, appraisal, and engineering work.
EPC: Engineering, Procurement, and Construction — a later development phase that immediately follows a final investment decision. Typically indicates more advanced project maturity.
FAQ
How much CO2 storage capacity is under development in Europe?
CaptureMap’s latest transport and storage data shows a substantial European portfolio, with the majority of capacity still under development rather than already operational.
How much European CO2 storage capacity is past FID?
As of March 2026, 18.7 Mtpa of annual CO2 injection capacity is past FID.
How much is still pre-FID?
The remaining 351 Mtpa is still in pre-FID stages and may require considerable time to come into operation.
Which countries lead Europe’s CO2 storage portfolio?
The UK, Norway, Denmark, and the Netherlands stand out as the largest markets in the current portfolio.
Why does project maturity matter in CO2 storage?
Because not all capacity is equally likely to materialize on the same timeline. Operational and later-stage projects are more de-risked than projects still in feasibility.
What is Article 23 of the NZIA?
Article 23 is the part of the Net-Zero Industry Act that sets the EU objective of reaching at least 50 million tonnes of annual CO2 injection capacity by 2030 and creates the framework for assigning contributions to obligated producers. See Article 23 in Regulation (EU) 2024/1735 on EUR-Lex for the official legal reference.
