Integrated Hydrogen Supply for Steel Decarbonization

Decarbonization of the steel industry will necessitate large-scale supply of green hydrogen at an economical cost. Linde is the world’s leading supplier of hydrogen and has for many decades been providing hydrogen and related services across different industry sectors, including steelmakers. Today, Linde is developing the world’s largest PEM electrolyzer (24 MW) and preparing to scale this up by orders of magnitude to meet these green hydrogen requirements for steel. Reliability and uptime of these systems will be critical and assured with best-in-class operation. The system will also integrate the supply of oxygen from the electrolyzer that will be used with Linde’s oxygen-hydrogen technologies – readily applicable throughout the process chain – to optimize the overall fuel balance in the plant. Certain steel mills may find it feasible to capture and sequester or use their CO2 emissions. State-of-the-art solvent and absorbent based systems have been developed to separate CO2, H2, etc., from steel mill gases with optimized CAPEX and OPEX. These gases can be compressed, sequestered, or used in other processes to make chemicals.
