St Fergus Gas Terminal CCS

Shell had planned to develop a carbon capture project at the SEGAL gas terminal in St Fergus, Scotland, integrated with the Acorn CCS transport and storage network, to reduce emissions from gas compression operations. The project was designed to capture approximately 90 percent of site CO₂ emissions, equivalent to roughly 300,000 tonnes per year, by routing gas turbine flue gas to an on-site absorption-based capture system. Captured CO₂ would have been dehydrated, conditioned, and compressed to dense phase before being transported through the 102 km Goldeneye pipeline to the Acorn offshore storage site for permanent geological injection. The project was estimated to require approximately £100 million in capital investment and was intended to serve as an anchor source for the first phase of the Acorn CCS hub, enabling future third-party connections. The SEGAL carbon capture project was ultimately planned but not progressed to construction and has since been cancelled
