The debate over carbon storage capacity has been asking the wrong question. Instead of "Do we have enough storage space?" the real question is "How fast can we build the infrastructure to use it?" Global carbon storage potential is massive, even under conservative estimates. The challenge isn't geological capacity but deployment speed and scale.
Recent industry developments show we're hitting a turning point. The global capacity for capturing carbon dioxide is poised to double to over 100 million metric tons per year once currently under-construction facilities become operational. This surge represents more than technical progress. It's proof that carbon storage is becoming the foundation for comprehensive decarbonization strategies.
The numbers tell a compelling story. The global carbon capture and storage market was valued at USD 8.6 billion in 2024 and is estimated to grow at a CAGR of 16% from 2025 to 2034. This isn't speculative growth but investment backing real projects with concrete timelines.
Industrial carbon capture and storage (CCS) initiatives have seen significant growth in 2024, reaching 628 global projects. These aren't pilot programs anymore. Major facilities like Northern Lights in Western Norway and 1PointFive's STRATOS facility in Texas are operational or coming online.

Carbon storage works best as part of an integrated approach. It's not competing with renewables or hydrogen but enabling them. The technology fills critical gaps where electrification can't reach, particularly in cement, steel, and chemical production.
Manufacturing will drive the next wave of growth. After 2030, these hard-to-decarbonize sectors will account for 41% of annual CO₂ captured by mid-century. Different regions are focusing on different applications based on their industrial strengths and energy profiles.
"CCS will grow to capture 6% of global CO2 emissions in 2050 compared to just 0.5% in 2030"
DNV Energy Transition Outlook Report
Major energy companies aren't just making announcements. They're putting serious capital behind carbon storage projects. ExxonMobil acquired Denbury for $4.9 billion to access CO₂ pipeline infrastructure. Occidental purchased Carbon Engineering for $1.1 billion, then followed up with another DAC acquisition.
This investment pattern shows companies betting on long-term demand rather than short-term market opportunities. The infrastructure being built today will support decades of decarbonization efforts across multiple sectors.
| Company | 2030 CCS Target | Recent Investment |
|---|---|---|
| ExxonMobil | 30 MtCO₂/yr | $4.9B Denbury acquisition |
| Shell | 25 MtCO₂/yr | Northern Lights joint venture |
| Occidental | 15 MtCO₂/yr | $1.1B Carbon Engineering buy |
Policy support is accelerating deployment timelines. Government backing for projects like the Acorn Project in Scotland shows political commitment translating into infrastructure funding. Cumulative investments in CCS over the next five years are expected to reach about $80 billion.
The geographic distribution of investment reflects policy priorities. About two-thirds of projected capacity additions will occur in North America and Europe, with North America currently leading. This concentrated investment approach helps build the ecosystem needed for broader adoption.
"It is much cheaper to reduce emissions now than to try and retrieve them in the future. However, we are a long way from achieving net zero emissions by 2050 and we will need carbon dioxide removal technologies to play an important role"
DNV Energy Transition Outlook Report
Policy-driven growth is already lowering costs. DNV expects CCS costs to drop by about 14% by 2030, mainly due to reductions in capital costs for capture technologies and lower transport and storage expenses. This cost reduction comes from scaling manufacturing and improving operational efficiency.
The learning curve effect is accelerating. As more facilities come online, operators share best practices and equipment manufacturers optimize designs for mass production. This creates a positive feedback loop where lower costs enable more projects, which drive costs down further.
The foundation is being built right now. Carbon storage capacity isn't a theoretical limit but a deployment challenge we're actively solving. Current projects will create the infrastructure backbone that supports broader decarbonization efforts across industries.
This isn't about choosing between carbon storage and other climate solutions. It's about using carbon storage to enable faster, more comprehensive decarbonization. The companies and governments investing billions today are building the infrastructure that makes net-zero pathways achievable.
The question isn't whether we have enough storage capacity. We do. The question is whether we'll build fast enough to use it effectively. Based on current investment trends and project pipelines, that answer looks increasingly positive.
