Salzgitter Group’s largest steel subsidiary Salzgitter Flachstahl GmbH has commissioned Tenova for the construction of µDRAL, a demonstration plant for the production of Direct Reduced Iron, using up to 100% hydrogen as reducing agent. The plant is based on the ENERGIRON technology and will be installed on the premises of the Salzgitter steel mill at Salzgitter in Germany. The µDRAL will have a nominal production capacity of 100 kilograms per hour and will be operated with hydrogen and natural gas showing the flexibility of the technology in terms of fluctuating availabilities of reducing agents, including 100% hydrogen. The DRI produced by µDRAL will be both used in the blast furnace process to save injected coal and in the electric arc furnace of the Peine plant.

The ENERGIRON process, jointly developed by Tenova and Danieli, represents the base for the plant design and is the most feasible high-intensity H2 DR system available, already designed for extremely low CO2 emissions while processing virgin metallic units. This enables Salzgitter to achieve the long-term CO2 reduction targets, defined with SALCOS approach.
