North Sea Project Greensand confirms feasibility of safe CO2 storage
Sept. 12, 2024
INEOS Denmark and its 23 partners have submitted a final report on Project Greensand, their pilot carbon capture and storage (CCS) development in the Danish North Sea.
INEOS said Sept. 10 that Project Greensand - the world’s first cross-border CCS scheme - is now open for business and ready to receive large amounts of CO2 that would otherwise have been emitted into the atmosphere.

INEOS Denmark and its 23 partners have submitted a final report on Project Greensand, their pilot carbon capture and storage (CCS) development in the Danish North Sea.
The purpose of the pilot was to develop, test and demonstrate safe and efficient CO2 storage in the North Sea subsurface. Technical verification confirmed that the stored CO2 remains safely and permanently in the Nini West reservoir 1,800 m subsurface.
DNV provided independent verification of the results.
In mid-2023, Project Greensand received official safety approval from DNV. The classification society said at the time that the safety verification followed years of involvement in the entire value chain’s concept, design, components, underground sites and facilities. DNV said this safety verification covered everything from the fabrication by the individual subcontractors to the actual offshore installation.
Mads Gade, country manager at INEOS Denmark and commercial director at INEOS Energy, said, “We now have documentation that we have a well-functioning storage for CO2 in the North Sea subsoil, where large amounts of CO2 that would otherwise have been emitted into the atmosphere can be safely and permanently stored. We can see that the stored CO2 behaves as expected in the reservoir 1,800 m below the seabed. That confidence gives us a solid foundation to take the next steps that will be crucial for CCS in Denmark.”

INEOS announced Sept. 10 that the 23 partners behind Project Greensand have received complete technical verification that the pilot project has been successful.
This was the world’s first project to demonstrate that captured CO2 can be transported across maritime borders and stored offshore.
Lead partner INEOS has applied for approval on behalf of license partners Harbour Energy and state-owned Nordsøfonden for Denmark's first large-scale CO2 storage facility.
The main goals are to start CO2 storage in the North Sea by the end of 2025 or early in 2026 at an initial rate of up to 400,000 metric tons/year, rising to up to 8 MMmt/year from 2030.
