CO2 capture and utilization (CCU) by integrating water electrolysis, electrified reverse water gas shift (E-RWGS) and methanol synthesis

Abstract

• High temperature E-RWGS enables operation at high pressure. • Electrically heated RWGS reactor simplify methanol synthesis process. • Integration of electrolysis and E-RWGS produces methanol at 90% carbon efficiency. • Biogenic conversion of CO 2 into methanol archives negative emissions.
