Greening steel: moving to clean steelmaking using hydrogen and renewable energy

This study evaluates the feasibility of green hydrogen-based steelmaking [hydrogen-based direct reduced iron (H-DRI) & electric arc furnace (EAF)] in India by providing insights into the techno-economics and associated environmental benefits. It considers four-time horizons: 2020 (current), 2030 (medium-term), and 2040 to 2050 (long-term). Expanding India’s production capacity with the existing set of technology options in the iron and steel industry will significantly affect its future greenhouse gas (GHG) emissions. Hydrogen has the potential to decarbonise steel manufacturing which currently accounts for 35 per cent of GHG emissions from India’s manufacturing sector.
