In which fields will the CO​2​ be stored? Who owns those fields?

From the platform, CO2 will be permanently stored in empty (depleted) gas fields three to four kilometres below the North Sea floor. Porthos focuses on storing CO2 in the empty gas fields P18-2, P18-4 and P18-6.

TAQA has extracted gas from these fields and the fields are available for storage. From the existing platform of P18A, operated by TAQA, Porthos will inject the CO2 into the empty gas field.
