SALCOS® – Salzgitter Low CO2 Steelmaking
Bei der Stahlproduktion entstehen aktuell noch große Mengen CO2. Da die Einsparpotenziale jedoch immens sind, steht die Frage im Raum, wie eine klimafreundliche Stahlproduktion Realität werden kann. Das Projekt SALCOS ® der Salzgitter AG will genau das aufzeigen. Die CO2-Emissionen sollen dabei durch den Einsatz von Wasserstoff drastisch gesenkt werden.
News (24.05.2023): Salzgitter bestellt Direktreduktionsanlage für die klimafreundliche Stahlproduktion bei Konsortium aus Tenova, Danieli und DSD Steel Group
Wie die Salzgitter AG heute bekanntgab, hat der Stahlkonzern einen Auftrag für die Errichtung einer Direktreduktionsanlage auf dem Gelände der Salzgitter Flachstahl GmbH vergeben. Auftragnehmer ist dabei ein Konsortium aus Tenova, Danieli und DSD Steel Group. Die beauftragte Direktreduktionsanlage beruht auf der sogenannten „Energiron ZR® Direct Reduction“-Technologie, die eine flexible Mischung von Wasserstoff und Erdgas ermöglicht. Die Anlage soll laut Salzgitter AG ab dem Jahr 2026 im Rahmen des SALCOS®-Projekts den Einsatz von Wasserstoff anstelle von Kohle in der Stahlproduktion ermöglichen. Die Anlage könne dabei bereits die Hälfte der bis 2033 geplanten Gesamtkapazität an Direktreduktionsanlagen stellen. Mehr erfahren

News (04/18/2023): Habeck and Weil hand over funding decision of almost one billion euros for SALCOS project to Salzgitter AG
As part of HANNOVER MESSE, Robert Habeck and Stephan Weil today handed over a funding notification worth almost one billion euros to Salzgitter AG. Funding is being provided for Salzgitter AG's SALCOS project, in which a hydrogen-capable direct reduction plant is to be used to enable climate-friendly steel production. Around 700 million euros in funding is being provided by the German government, while the state of Lower Saxony is supporting the project with 300 million euros. More on this
News (08.03.2023): Network operators cooperate on the future supply of natural gas and hydrogen to the Salzgitter industrial site
Salzgitter has not yet been connected to the emerging hydrogen network. The infrastructure concept that has now been agreed includes a new direct connection of Salzgitter to Gasunie's gas pipeline network and the efficient use of Avacon's existing gas infrastructure. More...
News (07/13/2022): Salzgitter AG decides to invest in the development of climate-friendly steel production!
The Supervisory Board of Salzgitter AG has approved the investments for the development of green steel production in Salzgitter. Initially, 723 million euros are to be invested for this purpose in order to gradually convert steel production in such a way that significantly fewer emissions are generated. More...

Currently, Salzgitter AG still produces pig iron from coal and iron ore in blast furnaces - a process that releases a great deal ofCO2. In order to make steel productionless CO2-intensive and more climate-friendly in the future, the blast furnaces used up to now are to be replaced by direct reduction plants in the SALCOS (SALZGITTER LOWCO2 STEELMAKING) project. Direct reduction produces sponge iron from iron ore and hydrogen. This process does not produceCO2, but only water, which can be used for further process steps.CO2 emissions are to be reduced by more than 95% through this conversion. The first plant could go into operation in 2026.
The direct reduction process is to use green hydrogen, which Salzgitter AG intends to produce in part itself. Two further hydrogen projects have been developed for this purpose: In the Wind H2 project, wind energy is to be used for hydrogen production, and in the project GrInHy2.0 industrial waste heat (by means of a high-temperature electrolyzer) is to be used for electrolysis. The µDRAL project will use the world's first direct reduction plant in an integrated smelter that can be operated flexibly with hydrogen and natural gas.
