ANDRITZ will incorporate pressurized alkaline electrolyzer technology from HydrogenPro. Starting in 2026, the plant will produce around 9,000 tons of green hydrogen per year, which will be used to produce green steel. This will mark the start of the industrial utilization of hydrogen under the SALCOS® program.
The SALCOS® program will be realized in three stages. The first stage will be operational as early as 2026 and will comprise a direct reduction plant, an electric arc furnace (both previously ordered) and the 100 MW electrolysis plant for green hydrogen production. The conversion to a virtually CO2-free steel production at the Salzgitter site is to be completed by the end of 2033, well ahead of the statutory requirements.
Ulrich Grethe, Chairman of the Salzgitter Flachstahl GmbH Management Board, explained: “The commissioning of the electrolysis plant marks a significant step in the SALCOS® program and underlines our leading position in the transformation of the industry. In order to enable us to reduce the CO2 footprint of our steel production in the future, it is imperative that we connect to the emerging hydrogen infrastructure as quickly as possible. This is the only way we will be able to fully exploit the potential of SALCOS®. Here, policymakers are now also called upon to remove bureaucratic roadblocks and accelerate the development of a hydrogen infrastructure.”
Domenico Iacovelli, ANDRITZ GROUP Executive Board Member, said: “We are proud that Salzgitter selected us as a partner and look forward to contributing to their ambitious program towards green steel production. The compact design of our green hydrogen plant perfectly fits into the existing infrastructure. Our vast experience in executing large-scale projects gives us a solid foundation for implementing this innovative project in collaboration with our partner HydrogenPro, whose pressurized electrolyzer stacks are very well suited for large-scale industrial applications.”
The financing of stage 1 of SALCOS® has been secured by subsidies from the Federal Republic of Germany and the State of Lower Saxony, as well as through Salzgitter AG’s own substantial funds.
