Hydrogen: The Future of Iron Making Industries

As the world focuses on reducing environmental pollution and greenhouse effect, there is a growing emphasis on minimizing direct CO2 and CO emissions. This can be achieved by decreasing the utilization of coal and coke-based iron ore reduction processes and transitioning towards natural gas-based iron ore reduction processes. In this situation, hydrogen (H2) is playing a very crucial role in the iron ore reduction scenario. Since H2 gas is environmentally benign and does not emit harmful or toxic gases, it offers a promising alternative to traditional blast furnace-basic oxygen furnace (BF-BOF) routes. Several alternative routes are being explored to replace the BF-BOF process, including the Hydrogen Breakthrough Ironmaking Technology (HYBRIT) and hydrogen-based direct reduced iron-electric arc furnace (H-DRI-EAF) processes, as well as DRI-EAF processes like Midrex and HyL. These innovative approaches have the potential to significantly reduce CO and CO2 emissions, with HYBRIT and H-DRI aiming for near zero emissions and achieving reductions of 40-60% in CO and CO2 emissions.
