The MIDREX plant is extremely flexible and can accommodate the initial transitions from a carbon to a hydrogen economy
The steel industry, especially traditional ironmaking, is among the largest contributors to greenhouse gas emissions – in the range of 7-9% of total emissions – because of its significant reliance on coal.
While the natural gas-based MIDREX Process, paired with an EAF has the lowest CO2 emission of any steelmaking route using iron ore, there is room to further decrease emissions by using hydrogen as a fuel and chemical reactant in the process.
The best possibility for now and the near future is to use green hydrogen to produce DRI as feedstock for steelmaking, this is known as MIDREX H2.
Today, hydrogen is not currently available at sufficient scale and low enough cost for rapid adoption. However, the proven MIDREX Process is available to help transition to the Hydrogen Economy.
The standard MIDREX NG flowsheet, MIDREX NG with partial substitution of hydrogen, and 100% hydrogen MIDREX H2 provide a staged transition to the Hydrogen Economy.
