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 of 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. But 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.

ArcelorMittal commissions Midrex to design demonstration plant for hydrogen steel production in Hamburg
In preparation for the future, ArcelorMittal will build a demonstration plant at ArcelorMittal Hamburg (Germany) in collaboration with Midrex. This 100,000 tons per year module will utilize 100% hydrogen as the reductant first sourced from the existing MIDREX plant. Green hydrogen produced from renewable energy sources can be added or substituted at later stages.
