Anglo American to Support Green Steel Initiative of Salzgitter
Salzgitter AG subsidiary Salzgitter Flachstahl GmbH has signed a memorandum of understanding with Anglo American to jointly investigate an optimal iron ore supply for the direct reduction process. Anglo American is one of the world's leading mining companies. The main goal of the joint research work is to minimize the CO2 footprint of steel production. This also includes the consideration of process and logistics chains that are as low in CO2 as possible. Salzgitter Flachstahl GmbH CEO Mr Ulrich Grethe said "With this project we are pushing further important milestones towards a CO2 low carbon steel production ahead. With our SALCOS ® technology concept, we want to implement the most energy-efficient and fastest way to decarbonise steel production. We are pleased to have Anglo American, one of our long-standing, large suppliers of high-quality ores, as a partner for joint considerations and possible projects. "
SALCOS stands for "SAlzgitter Low CO2 Steelmaking" and is the transformation concept for almost CO2 free iron and steel production. The carbon-based blast furnace route at Salzgitter Flachstahl will gradually be replaced by direct reduction plants from the middle of this decade until 2045 at the latest, which will initially produce with natural gas and then flexibly with a steadily increasing proportion of hydrogen. The hydrogen generation and the electric arc furnaces required for the new process route are to be operated exclusively with electricity from renewable sources. In this way, CO2 emissions from steel production can be reduced by 95 percent by 2045.
The new, low CO2 production systems and production processes place special demands on the properties of the raw materials, their treatment processes and logistics.
