The winding road toward zero-carbon iron

By Mitsubishi Heavy Industries (MHI) Group
Iron and steel production currently accounts for up to 10% of global CO2 emissions. As industry and governments strive to meet 2050 targets, it is essential to identify new energy sources. Green hydrogen can reduce the carbon intensity of steel by 75%, and 2021 saw unprecedented momentum in the hydrogen energy market – now is the time to embrace the potential of hydrogen to decarbonise industrial processes. This white paper presents a technical analysis of different process routes for liquid steel. It demonstrates that zero-carbon steel is attainable using green hydrogen.
