Four North Sea gas production wells have officially been converted to CO2 injection wells as part of the Port of Rotterdam CO2 Transport Hub and Offshore Storage (Porthos) project in the Netherlands, marking their readiness for CO2 injection, expected in autumn.

This first large-scale CO2 transport and storage project to be realized in the EU and the first offshore carbon capture and storage (CCS) project in the Netherlands is designed to transport CO2 captured from industry through the Port of Rotterdam to depleted gas fields in the North Sea, approximately 20 kilometers off the coast, where it will be permanently stored at a depth of more than 3 kilometers beneath the seabed.
