Carbon Catalyst Limited (CCL) and Perenco UK (PUK) have achieved a significant milestone as they've secured a carbon storage license from the North Sea Transition Authority (NSTA) for advancing the Poseidon carbon capture and storage (CCS) initiative in the Southern North Sea region of the UK Continental Shelf.
Illustrated in the map below, the Poseidon CCS project is an ambitious undertaking aimed at permanently sequestering approximately one billion tonnes of carbon dioxide (CO2) into the largest depleted gas field in the UK, which is under the operation of PUK, known as the Leman gas field. Additionally, the project encompasses adjacent storage reservoirs covered by the carbon storage license. With an anticipated operational commencement in 2029, Poseidon will commence CO2 injection at a rate of 1.5 million tonnes per annum (MMtpa), with this capacity set to increase to an impressive 40 MMtpa over a span of 40 years. The Poseidon project will create vital connections between CO2 emitters situated in East Anglia, London, and the broader Southeast of the UK. This connectivity will be facilitated through the utilization of the PUK-operated Bacton Gas Terminal, serving as the central conduit for transporting CO2 to the offshore Poseidon geological storage sites.
Henry Morris, who serves as the Executive Director at Carbon Catalyst, expressed his enthusiasm for the project, stating, "Poseidon has the potential to significantly contribute to the UK's decarbonization efforts by sequestering up to 40 million tonnes of CO2 annually into the vast depleted Leman gas field and the overlying aquifer system."
