Thyssenkrupp to supply lower CO2 emission electrical steel to Siemens

German steelmaker Thyssenkrupp has received an order for the supply of lower carbon emission grain-oriented electrical steel to Siemens Energy, Germany's biggest steelmaker said Feb. 20.

The carbon emission-reduced steel will be installed in nacelles of offshore wind turbines and delivery will take place over three years until the end of 2026.

According to Thyssenkrupp, more than 12,000 mt of CO2 emissions will be avoided by using a processed scrap recycling product in the blast furnace at the Thyssenkrupp Steel site in Duisburg as well as using a mass balance approach.

Siemens Energy will manufacture the 700 transformers using Thyssenkrupp's steel at its Weiz plant in Austria. The transformers will later be used at Siemens Gamesa's offshore wind power plants in Germany, UK and France. The first project equipped with these CO2-reduced transformers will be Ocean Winds' Moray West offshore wind farm, in the UK.

Tilo Else, vice president Procurement Grid Technologies at Siemens Energy, said that the supply agreement will be a "decisive" step toward reducing Scope 3 emissions.

"The fact that we are now using the high-tech powercore electrical steel in the same quality in a CO2-reduced version is an important step towards the decarbonization of our entire process chain," Else said.

Both companies also called for a standardization of carbon emission-reduced steel and more transparency surrounding CO2 emission cuts.
