Denmark Starting Signal for successful CCS
Off Denmark's coast, Wintershall Dea is using further potentials for low-carbon energy supply.
Wintershall Dea has been producing oil successfully off the coast of Denmark since 2003. Today, Wintershall Dea has equity in the two oil fields Cecilie and Nini which are located in the Danish Central Graben and expected to remain in production until 2024. Further, Wintershall Dea draws on the potential of CO2 storage technologies for a cleaner energy future as one of the core members of the Project Greensand Consortium.
Where we operate in Denmark
Wintershall Dea’s concessions are located off the western coast of Denmark: Close to the border of the Norwegian North Sea, oil is produced from the Nini and Cecilie fields.

Project Greensand
The Project Greensand Consortium aims to use depleted offshore oil reservoirs in the Danish North Sea to permanently store CO2 captured at onshore industrial facilities. The project has cleared a first major hurdle in fall 2020 with the certification of the Nini West subsea reservoir as a feasible gas storage. This certification confirms that the reservoir is conceptually suitable for injecting 0.45 million tonnes CO2 per year per well for a 10-year period and that it can safely contain the CO2 in compressed form. In August 2021, the consortium moved ahead to the pilot phase. The pilot's first offshore injection took place in early 2023. If successful, the pilot would lead to full-scale CO2 storage in the Nini West field by 2025. In December 2021, the project was granted a €26 million funding award from the Danish Energy Agency.
