December 1, 2023 – Steel production causes significant emissions of carbon dioxide. To decarbonize steel production and its high carbon dioxide emissions, Fraunhofer researchers, TS ELINO GmbH and Salzgitter AG are working on converting an existing steel mill to climate-neutral production methods. The aim is to produce steel by the direct reduction of iron ore with hydrogen, which would completely replace harmful coke as a reducing agent. The hydrogen required for this method is produced using electrolysis processes with electricity generated from renewable energy sources. Overall, this could reduce carbon dioxide emissions by up to 97 percent. The decarbonization of the steel industry would therefore contribute significantly to protecting the climate.
