MACOR completes the feasibility study on the reduction of CO2 emissions in the steel mill using renewable energies

By 2050, Salzgitter AG plans to have completed a conversion to virtually CO2-free crude steel production within the framework of the SALCOS® project (Salzgitter Low CO2 Steelmaking). Until now, the iron oxide in the ore has been reduced with coal, which is associated with high CO2 emissions – steel production accounts for around seven percent of global CO2 emissions. If instead green hydrogen, produced by electrolysis using electricity from renewable energies, is used in place of coal in a so-called direct reduction process, up to 95 percent of CO2 can be saved on the way to crude steel production. Of course, this cannot be achieved overnight, as the conversion is not only associated with high investment costs but is also technically demanding.
