Unlocking Denmark's CO2 Storage Potential – A Report by GEUS
The evaluation, outlined in the GEUS Report 2020/46 titled "Capture, Storage, and Use of CO2 (CCUS): Evaluation of the CO2 Storage Potential in Denmark," goes beyond the North Sea region covered in previous bids, extending to five onshore areas and three coastal zones while considering Natura2000 areas.
To ensure environmental considerations, the Danish Energy Agency has added a buffer zone of 5 km to the identified GEUS areas, as depicted in Figure 1-1 on the map.
Key Findings
GEUS estimates the current potential for geological CO2 storage in Denmark to be up to 22 Gt CO2. This substantial capacity positions Denmark's subsurface as highly suitable for geological CO2 storage in an international context.
In comparison, the government's climate program for 2021 outlines a technical potential for the geological storage of Danish CO2 at approximately 9 million tons. This indicates that, beyond capturing and storing immediate domestic CO2 emissions, Denmark's subsurface has the capacity to accommodate larger volumes of CO2 from other nations.
