EU's first full-scale carbon storage project Greensand starts operating in Danish North Sea
miningweekly.comINEOS has started operations at Greensand, the European Union's first full-scale carbon dioxide storage project, located in the Danish North Sea. The initial phase can store up to 400,000 tonnes of CO2 per year, with plans to scale to 4 to 8 million tonnes annually. CO2 from Danish biomethane plants is liquefied, trucked to the Port of Esbjerg, and shipped to the depleted Nini West oil field for injection about 1,800 meters below the seabed. The project marks a step forward for EU carbon capture and storage, though Norway's Northern Lights began storing CO2 in August 2025 as a non-EU member. Greensand's early capacity is small relative to Europe's emissions, but the scale-up potential and the use of existing oil infrastructure could inform future projects. The article focuses on the operational start and the logistics chain, but does not detail costs, monitoring plans, or how the stored CO2 will be accounted for over time.
