Capture and storage of CO₂: Effective climate protection
Climate change is one of the greatest challenges of our time. In Denmark, a broad political majority has pointed to carbon capture and storage – also known as CCS – as an important tool to achieve climate goals. CCS is a tool that, together with the green transition, will help to counteract climate change.
Timeline
The consortium consisting of Harbour Energy, INEOS Energy, and the North Sea Fund was awarded a licence in June 2024 to explore the potential for CO₂ storage in the Gassum area.
In accordance with the work programme approved by the Danish Energy Agency, the consortium will soon carry out an evaluation of existing 2D seismic data, new 3D seismic data will be collected, and there will be one exploration borehole and two delineation boreholes drilled.
The evaluations conducted and data collected will form the basis for assessing whether the area is suitable for safe CO₂ storage. If the exploration shows that this is possible, the consortium must apply to the authorities for approval for storage. Such approval is necessary for the project to proceed. If all goes as expected, CO₂ could be stored underground from 2029.
During the exploration phase, the consortium will focus on ensuring that the collection of seismic data and the drilling operations will cause the least possible disruption to local residents. Prior to the individual phases of the project, there will be an emphasis on informing the local residents so that everyone is aware of what is happening both above and below the ground.

About us
The Greenstore consortium consists of companies with extensive expertise and experience in energy production, both onshore and offshore. Harbour Energy, which is the operator in Greenstore, can draw on decades of experience in onshore energy production, including exploration, development, and production, and also holds five offshore CCS licenses. INEOS Energy is an experienced operator throughout the value chain of offshore energy production and is also the leader of the Greensand consortium, which develops CO₂ storage in the Danish part of the North Sea. The North Sea Fund is the Danish state's underground company and participates, among other things, to ensure the project's benefit for Danish society.
The consortium collectively possesses deep knowledge of the subsurface, including geology and petrochemical seismology, modeling and monitoring, which can contribute to the evaluation and development of CO₂ storage.
