Cosmo Energy Holdings and Sekisui Chemical Co. have finalized a basic agreement on a joint study toward car-bon dioxide (CO2)-to-valuables conversion (carbon cap-ture and utilization) using Sekisui’s technology. Sekisui’s chemical looping reaction technology con-verts CO2 to carbon monoxide (CO) at a high CO2 con-version rate of 90% using a unique catalyst and reaction process developed in-house. Through the joint study, the two companies will examine factors such as the CO2 reduction effect and investment profitability, with the aim of producing sustainable products derived from CO2 emitted from refineries and other Cosmo facilities.
