Tenova and Salzgitter AG signed a memorandum of understanding to cooperate on SALCOS (Salzgitter low-CO2 steelmaking). SALCOS is a concept for a significantly CO2-reduced steel production. The aim is to undergo a transformation process of the integrated steelmaking route, moving from carbon-intensive steel production based on blast furnaces toward a direct reduction and electric-arc furnace route, including the flexible incremental utilization of hydrogen. This concept is capable of reducing CO2 emissions up to 95% with respect to the entire steel production route.
As part of the agreement, Tenova will provide ENERGIRON-ZR direct reduction technology with integrated CO2 absorption system, which was jointly developed by Tenova and Danieli.
