CO2 Transport and Storage
Why is it important?
In the Net Zero Emissions by 2050 Scenario, CO2 transport and storage infrastructure underpins the widespread deployment of carbon capture, including carbon dioxide removal via direct air capture with storage and bioenergy with carbon capture and storage.
Where do we need to go?
With growing plans to equip facilities with CO2 capture, a gap is starting to emerge between anticipated demand for CO2 storage and the pace of development of storage facilities. In the absence of further efforts to accelerate CO2 storage development, through government or private-sector exploration, the availability of CO2 storage could become a bottleneck to CCUS deployment.
What are the challenges?
A growing number of projects are choosing to focus either on CO2 capture or on CO2 transport and storage. A “part-chain” approach can reduce commercial risks and promote efficiencies but relies on close coordination and alignment in the development of each element of the CCUS value chain.
Tracking CO2 Transport and storage
Transport and storage infrastructure for CO2 is the backbone of the carbon management industry. Planned capacities for CO2 transport and storage surged dramatically in the past year, with around 260 Mt CO2 of new annual storage capacity announced since February 2023, and similar capacities for connecting infrastructure. Based on the existing project pipeline, dedicated CO2 storage capacity could reach around 615 Mt CO2/yr by 2030, which is higher than currently planned capture capacity. This is a positive outlook for the CCUS industry, signalling strengthened market conditions driven primarily by policy implementation and co-ordinated alignment of the CCUS value chain by operators. However, this remains insufficient to meet the around 1 000 Mt CO2/yr by 2030 called for in the Net Zero Emissions (NZE) Scenario.
Development in major regions has advanced significantly in 2023, and some countries have announced first-ever projects
Development in major regions has advanced significantly in 2023, and some countries have announced first-ever projects
Countries and regions making notable progress include:
- Europe continues to make progress to advance CO2 transport and storage infrastructure with now over 160 Mt CO2 of storage capacity planned by 2030, mostly around the North Sea. Notably, the Porthos transport and storage project in the Netherlands reached a final investment decision (FID) in October 2023. The pilot phase of Project Greensand in Denmark also became operational in March 2023, with a first shipment of liquid CO2 from Belgium to a depleted oil field in the Danish North Sea for storage. Beyond the North Sea, the Ravenna hub is set to start injecting 25 kt CO2 per year offshore Italy in 2024, and storage projects continue to make progress in Croatia, Bulgaria, France and Greece.
- Initial licensing round for CO2 storage is also advancing in Europe. As part of their first-ever licensing rounds, the United Kingdom awarded 21 CO2 storage licences and Denmark awarded three CO2 storage licences. In Norway, two CO2 storage areas in the North Sea were opened to applications in March 2024.
- The European Commission provided over USD 500 million to CO2 transport and storage projects under its Connecting Europe Facility programme that funds projects across member states. This follows the Commission’s proposed Net Zero Industry Act, which was released in March 2023 and sets an annual CO2 injection target of 50 Mt CO2/yr for 2030.
- Japan issued a CCUS roadmap in January 2023, setting an annual CO2 storage target of 6-12 Mt CO2 per year for 2030 and 120-140 Mt CO2/yr for 2050. In June 2023, seven CCUS hubs were selected for funding by JOGMEG.
- The United States continues to increase CO2 storage capacity with 2.5-fold increase in planned capacity by 2030 in 2023 compared to 2022. An FID was also taken for a CO2 sequestration hub in California, and permit applications for CO2 injection in dedicated storage sites have increased dramatically in the last years, with now 43 projects with permits currently under review. In April 2024, the United States announced USD 11 million for four CO2 transport projects.
- The Asia-Pacific region has seen rising commitment towards CO2 infrastructure, including project announcements from China, Malaysia, Singapore, and Thailand for the first time ever, and further expansion of the CO2 management industry in Japan, Korea and Indonesia.
Status of CO2 storage infrastructure in development vs. planned capture capacity by region, 2023
OpenDedicated CO2 storage capacity is matching capture plans as infrastructure-specific announcements surge
Dedicated CO2 storage capacity is matching capture plans as infrastructure-specific announcements surge
Historical storage capacity has been largely tracking capture capacity since 1996 and the first injection at the Sleipner field of 1 Mt CO2/yr. Today, global capture and storage capacity both culminate at just over 50 Mt CO2/yr, with a minor discrepancy between the two that is attributed to CO2 utilisation.
Over the past two years, there has been a large acceleration of CO2 management infrastructure development within the CCUS landscape. Planned capacity for CO2 storage for 2030 has increased by 70% in the last year, reaching around 615 Mt CO2 per year. This is currently greater than planned capture capacity by 2030 based on currently available data, with variations seen across regions. However, efforts must continue to increase on both CO2 capture and CO2 storage across all regions to address the gap observed between planned capacities and the global target outlined in the NZE scenario for 2030.
A monumental shift from CO2-EOR towards dedicated CO2 storage in the near future signals strengthened action towards net zero commitments
Today, just over 10 Mt CO2/yr of captured CO2 is injected for dedicated storage within ten large-scale sites, but based on the project pipeline planned storage capacity could reach around 615 MtCO2/yr by 2030. Out of this planned capacity, at least 80% could be in dedicated storage sites, against just around 20% of storage capacity in operation today. A combination of factors which include regulatory requirements for the incentivisation of dedicated CO2 storage development (such as in Canada), and the critical role of CCUS in facilitating the transition to net zero for certain economies (e.g. Norway, the United States, and the United Kingdom), is helping driving this shift away from CO2-EOR.

Pioneering shipment of CO2 for dedicated storage in Europe paves way for future CO2 shipping ventures
Shipping of CO2 for the purpose of geological storage made a landmark achievement in early 2023. The pilot phase of Project Greensand in Denmark pioneered CO2 shipment with the first volumes of liquid CO2 transported from Belgium and injected into a field in the Danish North Sea for storage. Similarly to pipelines, a CO2 shipping service creates connectivity for industries looking to decarbonise but located far from viable storage assets. Other examples of shipping projects in development include:
- Construction is underway for the first CO2-receiving terminal (Northern Lights project) in Norway, for commissioning in 2024. In December 2023, Northen Lights placed an order for a fourth LNG-fuelled and wind assisted LCO2 carrier, which currently grants the Norwegian project the world’s largest CO2 dedicated fleet.
- Chevron and Mitsui O.S.K Lines established an agreement in 2022 to investigate the feasibility of transporting CO2 from Singapore to storage locations offshore in Australia. This complements a memorandum of understanding signed between Singapore and Australia, as well as a recently announced industrial consortium to explore CCUS solutions in Singapore.
- The NoordKaap project will ship CO2 collected from European emitters in Germany, Scandinavia, Belgium and northern France for storage in the Norwegian North Sea and offshore in the Netherlands. The first storage licence application has been submitted to the Norwegian Ministry of Petroleum and Energy for approval.
- Japanese energy companies plan to join the Bayu-Undan CCS project in Australia looking to transport CO2 via shipping from Japan for offshore storage in the Timor Sea.
- In July 2023, an agreement between Capital Gas Ship Management, Hyundai Mipo Dockyard, and Lloyd’s Register was signed with the intent of working together for the construction of two 22,000m3 low-pressure LCO2 carriers that will be delivered in 2025 and 2026.
Feedbacks between CO2 capture and infrastructure capacities can sustain an efficient balance between CO2 supply and storage demand
Multi-user CO2 transport and storage infrastructure is becoming a mainstream business model in the CCUS landscape with the emergence of new players. Now that at around 14 500 km of pipelines are under development globally – with far more expected, as many announced infrastructure projects have not disclosed planned pipeline length – under-used CO2 infrastructure capacity is available in some regions. Depending on location, this can enable a greater number of small-scale emitters to consider CO2 capture a feasible option to decarbonise their operations. Examples of major pipeline networks run by specialist operators where this may be possible include:
- The 240 km Alberta Carbon Trunk Line in Canada, operated by Wolf Midstream since 2020, has a design capacity of around 15 Mt CO2/yr and aims to connect more facilities in the future, even though it currently transports less than 2 Mt CO2/year from two sources. In September 2023, Wolf Midstream announced an FID on a 40 km pipeline extension, the "Edmonton Connector", which will expand the ACTL network into the Edmonton region to enable greater emissions-reduction opportunities.
- In the United States, in addition to the approximate 9 000 km of operating pipeline that is transporting around 70 Mt of CO2 annually, three cross-state pipeline projects across the Upper Midwest region had been planned to collectively add nearly 6000 km of new pipeline to the existing infrastructure network. However, recent rejections of permit applications have created setbacks for these projects, and resulted in the cancellation of the Heartland Greenway pipeline (planned to be longer than 2 000 km).
- In continental Europe, multiple cross-border infrastructure projects are being developed to access storage resources in the North Sea. In March 2023 Wintershall Dea and Fluxys jointly proposed a major open-access CO2 transmission network to connect industrial clusters in Germany to Belgium’s Zeebrugge Port, with capacity to transport 30 Mt CO2/yr. There are also plans for an onshore carbon transit grid that will serve as a collection point at the Zeebrugge port to facilitate onwards transport for storage in the North Sea by the offshore Belgium-Norway trunk line (1 000 km). This joint venture between Equinor and Fluxys will aim to transport 20 to 40 Mt CO2/yr.
A growing number of diverse projects for CO2 transport and storage, as well as innovative monitoring techniques, are being piloted around the world

New monitoring techniques can ensure the safe and effective roll-out of CO2 storage
Monitoring, measurement and verification technologies continue to be developed. In Denmark, a new first-of-a-kind buoy will in 2023 be subject to final tests conducted by Resen Waves as part of Project Greensand. The device utilises renewable wave energy to collect and transfer CO2 storage data remotely to operations on land. This offshore monitoring method could reduce costs and avoid occupational injuries associated with offshore surveying activities.
Growing diversity in demonstration of unconventional storage resources
CO2 mineral storage involves using highly reactive mafic rocks to sequester CO2 is also being increasingly developed. In January 2023, 44.01 announced a new collaboration with ADNOC and other partners to launch a commercial scale pilot project in the United Arab Emirates to inject CO2 into peridotites, a type of rock that contains a high proportion of reactive minerals to CO2. Moving forward, more demonstration projects are needed to assess whether these resources can store CO2 at commercial volumes.
New tanker design for next generation commercial CO2 carriers
The food and beverage industry is currently the main shipper of CO2 and usually transports it at medium pressure (13 to 18 bar and -30°C to -28°C) as users have no need to move high volumes and do not require large cargos. In Japan, Mitsubishi Shipbuilding, launched the construction of a demonstration ship designed for CCUS initiatives in March 2023. In Europe, the Hunter Group and DNV entered a joint agreement in 2023 to design a 40 000 – 70 000 cubic metre vessel to be available for CO2 transportation in European waters.
Government support for CO2 transport and storage infrastructure is growing
Government support for CO2 transport and storage infrastructure is growing
Countries and regions have recognised the importance and urgency of developing CO2 transport and storage infrastructure. A number of countries have recently enacted policies:
- The Connecting Europe Facility-Energy (CEF-E) is a funding instrument to help implement large-scale cross-border energy infrastructure in the European Union. In 2023, four CCUS hubs were awarded over USD 500 million through CEF-E, a massive increase from the USD 170 million awarded to three CCUS hubs in 2022.
- In the United Kingdom, the North Sea Transit Authority awarded 21 CO2 storage licences to 14 companies as part of the UK’s first-ever licensing round. Once in operation, the new storage sites could store up to 30 Mt CO2 by 2030, around 10% of the country’s annual emissions.
- In Denmark, three CO2 storage licences were awarded in February 2023 as part of the country’s first licensing round, including one licence to the Greensand project, which started pilot operations in March 2023, and two licences to TotalEnergies. The second licensing round was opened in December 2023, with projects expected to be awarded in 2024.
- In Norway, two CO2 storage areas in the North Sea were opened to applications in March 2024.
- Facilitated by the Infrastructure Investment and Jobs Act, the Department of Energy (DOE) in the United States opened applications in 2023 for a nearly USD 2.3 billion funding announcement for CO2 storage and validation projects. In April 2024, the DOE announced USD 11 million to four CO2 transport projects under the same legislation.
- Germany made its re-entry into CCUS with plans to amend legislation to allow for the regulation of CCUS activities, including offshore CO2 storage.
- Japan is progressing on its draft CCS Business Act, which will establish a legal framework for CCUS across the value chain and allow for the transfer of closed CO2 storage sites to JOGMEC, a state-owned enterprise. It is also advancing a proposal to amend the London Protocol to allow for the transboundary storage of CO2.

Recommendations
-
For regions without an overview of storage resources, a top priority for policy makers should be to facilitate precompetitive assessments of CO2 storage resources. A standardised approach and taxonomy should be adopted, such as the Storage Resource Management System (SRMS), backed by decades of rigorous expertise in assessment of oil and gas accumulations, and used by the Oil and Gas Climate Initiative (OGCI) in their CO2 Storage Resource Catalogue.
For regions with more advanced CO2 storage initiatives, policy makers should work to accelerate administrative and permitting procedures, firstly by establishing a clear permit approval timeline and requirement framework, and secondly, by creating a “strategic projects” designation to make the process faster and more integrated, such as forming a one-stop shop for permitting.
-
Review existing laws and regulations that cover CO2 management activities to ensure they are fit for purpose to:
- ensure the safe and secure transport and storage of CO2;
- consider new business models that are arising in the CCUS landscape;
- ensure accessibility by third-parties;
- facilitate cross-border co-operation;
- address concerns regarding storage-specific liabilities and risks, and
- address regulatory obligations under emission trading systems, monitoring, reporting, and verification requirements, and the London Protocol.
Ensure policy support for CO2 infrastructure is available for all modalities of CO2 transportation including shipping, pipelines, rail and barge, without discrimination.

Recent policy support for CCUS hubs should send a strong signal to the private sector to leverage public funding and channel investment from across sectors. Heavy industry (which includes cement, steel and chemicals production) is a hard sector to decarbonise but can benefit from the economies of scale associated with multi-user infrastructure.
Cross-sector co-ordination is essential to the development of hubs, and heavy industry players should work closely with hub developers. Industry consortia and coalitions can provide a platform to facilitate this co-ordination. Northern, the CO2 transport and storage component of the Longship project in Norway, is currently under construction and on track to be the first operational CCUS hub with capacity to accept international CO2 sources.
Within the finance community, establish a club of first-mover investors to collectively unlock private capital for CCUS investment, particularly across the hard-to-abate sectors. Investors should seek to include CCUS-specific projects in environmental, social and governance (ESG) funds, and other low-carbon investment opportunities.
The insurance industry can provide specialised insurance products for storage and transport operators to provide different risk contingencies.
CO2 storage resources and their development
Carbon capture, utilisation and storage (CCUS) technologies are an important solution for the decarbonisation of the global energy system as it proceeds down the path to net zero emissions. CCUS can contribute to the decarbonisation of the industrial and power generation sectors, and can also unlock technology-based carbon dioxide (CO2) removal. However, its successful deployment hinges on the availability of CO2 storage. For widespread CCUS deployment to occur, CO2 storage infrastructure needs to develop at the same speed or faster than CO2 capture facilities.
