The permanent geological storage sites are situated more than 1500 meters below the seabed. These sites are characterized by one or more ‘seals’ positioned above the geological layers where CO2 is stored. Typically composed of thick layers of clay, these seals serve to effectively contain and prevent the escape of CO2.

The liquid CO2 will be transported by ship to a storage site in the North Sea where it will be offloaded and  injected through a well. Depending on the reservoir’s location, the transportation method may transition from ships to pipeline at a later date.

CO2 storage technology has been implemented globally for over 40 years. Rigorous evaluations precede the approval of reservoirs for permanent storage. Originally utilized for holding oil and natural gas, these reservoirs now play a crucial role in the responsible return of CO2 from these substances to its original location.

CO2 is stored at depths exceeding 1500 meters below the seabed. In the unlikely event of any CO2 escaping from permanent storage, a fraction of the net zero effect may unfortunately be compromised. Importantly, such an occurrence will have no adverse impact on the marine environment.

Yes, the authorities mandate continuous monitoring of all storage sites.
