thyssenkrupp Steel aims to save 30 percent CO2 in this decade alone. To achieve
this, four blast furnaces will be gradually replaced by direct reduction plants oper- ated with green hydrogen from 2025, each supplemented by smelting units, in order to turn the solid raw material into liquid pig iron. According to thyssenkrupp, two billion euros will be needed for implementation by 2030, and up to eight billion euros in investments will be needed for the com- plete transformation.
Decarbonisation cooperation
Salzgitter AG has also initiated the decar- bonisation of its processes and products.
It plans to start production of low-carbon on a new production route from the end of 2025. “The expected CO2 saving after com- pletion of the transformation will be more than 95 percent”, the company explains.
Salzgitter is entering into cooperation
to push forward decarbonisation. The Group has entered into an agreement with Uniper to create the SALCOS® project, which is part of the ‘Salzgitter AG 2030’ strategy. This project is to be supplied
with green hydrogen for the production of
climate-friendly steel by the international energy company Uniper. SALCOS® (Salzgit- ter Low CO2 Steelmaking) is a transforma- tion programme to convert production to a hydrogen-based route.
In Wilhelmshaven, Uniper is developing two projects with green hydrogen. Here, the company is planning an import terminal that converts ammonia back into hydro- gen. In addition, large-scale electrolysis is provided, which will generate green hydro- gen with an output of up to 1,000 MW. For this purpose, a direct connection of new offshore wind farms to be built in the North Sea will be examined.
Low-carbon steel for the automotive industry
Salzgitter has already agreed with Volkswa- gen AG to supply low-carbon steel from the end of 2025. Volkswagen plans to use this steel in future projects such as the Trinity
1 e-model. The automobile group wants to focus on reducing CO2 emissions where they are primarily generated, i.e. during automotive production. “In addition to the
Press releases
ArcelorMittal has successfully tested the use of green hydrogen in the production of direct reduced iron (DRI) at its steelworks in Contrecoeur, Quebec. The company views this test as an important milestone on the way to producing carbon-free steel via the DRI-based steel production route using green hydrogen as an input.
