Abstract

•CO2 valorization via electrified CO2 reforming of methane and reverse water–gas shift.•eRWGS ensures specific energy demands as low as 0.7 kWh/Nm3CO2 for CO2 valorization.•Joule-heated Rh/Al2O3 washcoated SiSiC foams demonstrate excellent stability over 75 h.•A new path for low carbon chemical synthesis utilizing captured CO2 and excess renewable electricity.
