The changing role of Ironmaking in the Transition to the Hydrogen Economy

Not scheduled
Oral Presentation CO2 Reduction and environmental aspects in the DRI industry


Dr Vincent Chevrier (Midrex Technologies, Inc.)


The steel sector is one of the largest industrial sources of global CO2 emissions. The mitigation of CO2 emissions is becoming critical in many countries for environmental and taxation reasons. While the natural gas-based MIDREX® Process paired with an electric arc furnace (EAF) has the lowest CO2 emissions of any steelmaking route, there is room to further decrease emissions using hydrogen as a fuel and chemical reactant. The best possibility for significantly reducing CO2 footprint in the future is to use “green” hydrogen as the energy source and reductant to produce DRI/HBI, which can be used as feedstock for steelmaking. This flow sheet concept is known as MIDREX H2TM. The supporting process details, calculations and experimental results that lead to this innovative process will be presented. Unfortunately, hydrogen is not currently available at a sufficient scale and a low cost for rapid adoption. This paper will review the required steps in the transition to (near) carbon-free ironmaking as well as the major technical and economic challenges. As “green” hydrogen becomes available and cost effective, the MIDREX Process can be converted to MIDREX H2 in stages, allowing steelmakers to take advantage of CO2 reduction immediately and further reduce emissions in the future without major capital expenditure.
