We are also pleased to partner with MHI Group — a proven leader in carbon capture technology — as we chart our journey in our race to decarbonization.”

MHI-EMEA CEO Kentaro Hosomi, commenting on the conclusion of the MOU, said: “As a market leader in decarbonization technology such as carbon capture, storage and utilization (CCUS), MHI Group is proud to support Alba and the Kingdom of Bahrain in reaching their ambitious sustainability goals. It is partnerships such as this that enable the industry to move quickly on the way to carbon neutrality.”
