Overview
- Danish King Frederik X officially opened the Greensand facility and the project moved into regular operation on Friday, September 18, 2026, the consortium said.
- The site uses the depleted Nini West oil field about 1,800 meters below the North Sea and will increase injections from pilot levels of roughly 15,000 tonnes a year to up to 400,000 tonnes annually at start-up.
- Ineos, Harbour Energy and state fund Nordsøfonden run the project and call it the EU’s first industrial-scale CO2 store, saying the site could in future hold four to eight million tonnes a year if demand rises.
- Currently the stored CO2 comes mainly from Danish biogas plants, and project partners say clearer rules and better market incentives are needed to attract large industrial emitters from countries such as Germany.
- Experts and campaigners say the geology makes long-term storage technically sound but warn that high costs, limited initial scale and the risk that CCS reduces pressure to cut emissions at source will shape whether the scheme grows.
