U.S. oil major ExxonMobil has increased its participation in the Acorn carbon capture project in Scotland by signing an Expression of Interest to capture, transport, and store CO2 from its Fife Ethylene Plant in Scotland.

ExxonMobil said on Wednesday that the agreement to include the ethylene plant, located in Mossmorran, Scotland , is in addition to an earlier announced Memorandum of Understanding to capture and store emissions from gas terminals at the St Fergus complex at Peterhead, Scotland, which includes ExxonMobil’s joint venture gas terminal.
