The first phase of the mapping of the subsoil on land at Kalundborg has now been completed as part of CO2 Storage Kalundborg's work to investigate the possibilities for safe and permanent storage of CO2. The project has collected a large amount of data that will form the basis for assessing the suitability of the subsoil. This is stated by CO2 Storage Kalundborg.
- We have now completed the first phase of the project, and we have taken a major step towards clarifying whether CO2 can be safely and permanently stored deep underground at Kalundborg. We have a very large amount of data, so we can now form a precise picture of the geology in the subsoil, says Ulrik Olbjørn, project manager at CO2 Storage Kalundborg.
The investigations began in March and were carried out with vibration equipment and geophones that collected data on the composition of the subsoil. Earlier this year, the mapping of the subsoil in Nekselø Bugt was also completed.
The collected data must now be analyzed to create a 3D map of the area. At the same time, CO2 Storage Kalundborg has applied for permission to establish a temporary drilling site at Snertinge, where the next phase of drilling and testing of the subsoil can begin at the end of 2025. The results of the investigations are expected to be completed in 2026.
- We are moving steadily and safely forward, and now we need to review the large amount of data with a compaction comb. It is crucial that we get an accurate picture of the subsurface. No one is interested in initiating CO2 storage at a later date if it cannot be done safely and responsibly, says Ulrik Olbjørn.
CO2 Storage Kalundborg is a collaboration between the energy companies Equinor and Ørsted and the Danish state - represented by the Nordsøfonden. Equinor is the operator and the majority owner with 60 percent of the license, while Ørsted has 20 percent and the state's subsurface company, Nordsøfonden, also has 20 percent.
