CO2 Storage Under the Sea: When Will the Infrastructure Be Built?

The German Bundesrat has recently approved a controversial amendment that allows for the storage of carbon dioxide (CO2) beneath the North and Baltic Seas. This legislative change is aimed at transporting harmful greenhouse gases to coastal areas where they can be stored or utilized by various industries. The new law also outlines the development of the necessary infrastructure to facilitate this process. Currently, in Germany, capturing and storing CO2 underground has only been permitted for research purposes. However, the amendment to the carbon dioxide storage law now enables companies to implement these technologies on a standard basis. This move is a significant step forward in establishing the infrastructure required for CO2 capture and storage (CCS), which is seen as a vital tool in preventing CO2 from reaching the atmosphere. While the potential for CCS is substantial, the technology known as CCU (carbon capture and utilization) also plays a role by allowing CO2 to be reused in products like fire extinguishing systems and carbonated beverages.

Infrastructure and Implementation

The Deutsche Presse-Agentur has investigated the current infrastructure and preparations underway for expansion. Although CO2 can be transported by trains, trucks, and ships, pipelines are considered more efficient. According to the Gas and Hydrogen Industry Association, CO2 is already being transported and utilized by the beverage and dry ice industries, primarily using trucks. However, Germany lacks an industrial CO2 pipeline network. It is anticipated that the private sector will be responsible for constructing these pipelines, with potential government support. In October, Minister Katherina Reiche announced a six-billion-euro funding program, which includes CCS and CCU technologies, with a target of completion by 2026. Several companies, including Open Grid Europe (OGE), are working on projects across regions like North Rhine-Westphalia, Schleswig-Holstein, and Lower Saxony.

Challenges and Opportunities

Despite existing CO2 tanks for the food industry in places like the Hamburg port, Germany currently has no storage facilities to meet future demand. The Ministry of Economic Affairs has stated that it does not plan or operate CO2 storage facilities, leaving this to private enterprises. In contrast, countries like Norway have been storing CO2 under the seabed since 1996, with companies like Equinor leading the way. The amendment also permits companies to store CO2 in depleted oil and gas fields, provided they obtain the necessary approvals. Planning is underway in coastal states to determine how CO2 can be shipped effectively. However, environmental groups have expressed concerns about the safety of storing CO2 under the seabed, pointing out the potential risks of leakage. For Germany to achieve its climate goals, the infrastructure is expected to be operational by the mid-2030s. However, there are concerns about the feasibility of this timeline. The Federal Association of Natural Gas, Petroleum, and Geoenergy has noted that investment will only be viable if it proves profitable, suggesting that CCS might only be implemented in certain regions, such as the Rhine-Ruhr area. Furthermore, the Association of Industrial Energy and Power Economy has indicated that private funding alone will not suffice for a comprehensive infrastructure. Early political intervention to resolve financing issues is deemed essential to meet the 2045 greenhouse gas neutrality target. In conclusion, while Germany has taken a pivotal step towards establishing CO2 storage infrastructure, significant challenges remain. The success of this initiative will depend on effective collaboration between government and industry, as well as addressing environmental concerns and ensuring financial viability.
