The CO2 is stored in depleted (empty) gas reservoirs under the bed of the North Sea off the coast of Rotterdam. The Netherlands has ample potential for the permanent storage of CO2 under the North Sea. The area just beyond the coastal waters of the Port of Rotterdam also offers gas reservoirs suitable for CO2 storage.

The depleted gas reservoirs in which ROAD plans to store CO2 are located in block P18 (P18-6, P18-4 and P18-2) of the Dutch continental shelf in the North Sea. The storage location is some 20 kilometres off the coast, under the bed of the North Sea, at a depth of approx. 3,500 meters. The CO2 will be injected from the platform and permanently stored. The capacity of the reservoirs is around 35 million tonnes of CO2.
