MIDREX H2
The future of ironmaking
Enabling the green steel transition at scale
MIDREX™ H2 is the world’s first full-scale project for hydrogen-based direct reduction technology, delivering proven decarbonization impact.
This technology, combined with electric melting, is capable of eliminating fossil fuels and reducing CO₂ emissions by up to 95 percent compared to traditional blast furnace/basic oxygen furnace (BF-BOF) steelmaking. It is specifically designed for 100 percent hydrogen operation or for majority hydrogen operation with minimal natural gas usage.
MIDREX H2 builds on the proven MIDREX™ Shaft Furnace and gas-based reduction process and its configuration includes the latest innovation from Midrex, an electric heater for the recirculating hydrogen-rich gas designed and supplied in partnership with the Tutco SureHeat business of Flex-Tek Group, a division of the UK-based engineering company Smiths Group PLC.
When to choose MIDREX H₂
Energy context
Projects with access to reliable, large-scale hydrogen supply, either available at start-up or secured as part of the project design.
Decarbonization goal
Maximize direct reduction emissions performance by operating primarily or fully on hydrogen from day one.
Typical project type
New-build DRI plants developed in regions with established or committed hydrogen infrastructure and supportive policy frameworks.
Design intent focuses on hydrogen-based gas circulation, electric heating of process gas, and integration with upstream hydrogen and power infrastructure.
What makes Midrex different? Their technology, their know-how, their commitment to work with their client beyond plant startup to make sure that the plant exceed the design capacity not only in terms of productivity but also in quality.
