German steelmaker Thyssenkrupp has received an order to supply grained low-carbon electrical steel to Siemens Energy, Germany's largest steelmaker said on February 20.
The low-carbon steel will be installed in marine nacelles wind turbines and will be delivered over three years until the end of 2026.
According to Thyssenkrupp, more than 12,000 tons of CO2 emissions could be avoided by using recycled scrap metal product in a blast furnace at a Thyssenkrupp steel mill in Duisburg, and also use a mass balance approach.
Siemens Energy will produce 700 transformers from Thyssenkrupp steel at its Weiz plant in Austria. The transformers will later be used in Siemens Gamesa's offshore wind farms in Germany, the UK and France. The first project to be equipped with these low-CO2 transformers will be Ocean Winds' Moray West offshore wind farm in the UK.
Thilo Else, vice president of network procurement technology at Siemens Energy, said the supply agreement will be a “decisive” step towards reducing Scope 3 emissions.
“The fact that we are now using the same quality high-tech electrical steel Powercore in a lower CO2 version is an important step towards decarbonising the entire our process chain," Els said.
Both companies also called for standardization of low-carbon steel and greater transparency regarding CO2 reductions.
