Salzgitter and Tenova took another concrete step towards climate-friendly steel production by signing a Memorandum of Understanding (MoU) at Hannover Messe 2019 for the realisation of SALCOS® (low carbon steelmaking).

SALCOS is a revolutionary concept designed by the two companies to significantly reduce CO2 in the production of steel. The aim is to gradually move away from carbon-intensive steel production based on blast furnaces, to a direct reduction and electric arc furnace route, with an increasing use of hydrogen.

According to Salzgitter, this concept is capable of reducing CO2 emissions by up to 95%. The two companies aim to jointly apply for public funding for the project.

Ulrich Grethe, member of Salzgitter AG’s Group Management Board, said the agreement with Tenova is another important step in the implementation of the SALCOS project.

“With this, we affirm our offer to politics and society to realise a low CO2 steel production in the near future,” he added.

Paolo Argenta, Tenova’s Executive Vice-President of Upstream, said, “Over the last years, Tenova has been heavily investing to develop technologies able to significantly reduce energy consumption and the environmental footprint of steel production.”

“Hydrogen plays a pivotal role in this revolution, and the SALCOS concept could represent an important milestone in our industry.”

“We are currently involved in a further study, GrInHy2.0, with Salzgitter AG and Sunfire GmbH, which has received the support of Hydrogen Europe and the European Commission. This should lead to another step toward the first full-scale initiative to move from coal to hydrogen in the steel production.”
