Electrified Carbon Cycling for Neutralizing the Steelmaking Industry

open access: yesCarbon Energy, EarlyView.
Steelmaking is energy‐intensive and heavily reliant on fossil fuels, contributing significantly to global carbon emissions. Developing a renewable processing approach compatible with existing infrastructure is urgent. Electrified carbon cycling based on CO2RR converts CO2 into CO, reducing coke usage and CO2 emissions, thus enabling carbon‐neutral ...
