Salzgitter has laid the cornerstone for what it says is one of the largest production plants for green hydrogen in Europe, Kallanish notes.
Starting from 2026, the plant will generate around 9,000 tonnes/year of green hydrogen to be used for the production of carbon-reduced steel. This will mark the start of the industrial use of hydrogen in the company’s SALCOS – Salzgitter Low CO2 Steelmaking – project. The 100 MW electrolysis plant will be supplied by Andritz.
A contract between the two companies was signed in September 2023 (see Kallanish September 2023). The engineering involves partner company HydrogenPro. The partner’s pressurised electrolyser stacks are particularly suited for large-scale industrial application, according to Andritz executive Domenico Iacovelli.
Separately, the steelmaker announces its plate-making subsidiary Ilsenburger Grobblech has signed a contract with wind turbine manufacturer Siemens Gamesa for the delivery of around 25,000t of heavy plate.
These will be used for the construction of 36 wind towers of Siemens Gamesa’s “GreenerTower” type. The special feature of this tower is its CO2eq emissions of less than 700 kg per tonne of steel, Salzgitter notes.
The CO2eq-reduced tower has been part of Siemens Gamesa’s product portfolio since 2024. The first use of the towers will be in the “Thor” offshore wind farm in the Danish North Sea. This is planned to be completed by the end of 2027 and have a capacity of more than 1,000 MW.
