Denmark's Greensand project in the North Sea has become the European Union's first full-scale carbon dioxide storage site to enter commercial operation. Opened at the Port of Esbjerg on September 18, 2026, the project injects CO2 captured from Danish biomethane plants into the depleted Nini West oil reservoir, about 250 kilometers offshore and 1,800 meters below the seabed. The operators, INEOS Energy, Harbour Energy, and Nordsøfonden, plan to expand from an initial 400,000 tonnes per year to between 4 and 8 million tonnes. The launch gives the EU an operating example of the full CCS chain: capture, road transport, shipping, and permanent storage. It also highlights the scale challenge. The EU's 2030 target is at least 50 million tonnes of annual injection capacity, so Greensand's starting volume is under 1 percent of that goal. The Commission's long-term plans assume roughly 280 million tonnes captured annually by 2040 and 450 million tonnes by 2050, mostly for cement, chemicals, and waste-to-energy plants. Whether the storage and transport network can grow fast enough to match those targets is now the main test for European carbon management policy.
