German steel maker thyssenkrupp is supplying first batch of bluemint Steel with 50% lower CO2 emissions to the Regensburg-based company SGB-SMIT for the production of transformers for new digital E.ON medium-voltage substations. The first small series is used by E.ON subsidiary Avacon. For the batch delivered to SGB-SMIT, reduced iron has been used in the Duisburg blast furnace, enabling a reduction in coal usage. Including all further processing steps in Duisburg and in Gelsenkirchen, a CO2 saving of 50% per ton of bluemint is achieved compared with conventional electrical steel. This means a reduction in the CO2 intensity of one ton of bluemint powercore from 3.7 tons to 1.8 tons.Since October 2021 thyssenkrupp Steel has been offering certified CO2-reduced steel under the bluemint brand. Production is initially taking place via the classic blast furnace route at the Duisburg site before the technological leap to hydrogen-based direct reduction technology from 2025. The Gelsenkirchen site is aiming for complete climate neutrality in the medium term, for example by using green electricity and biomethane in production as early as this year.thyssenkrupp Electrical Steel is European market leader for grain-oriented electrical steel. This complex special material ensures that transformers operate at high efficiency to transport energy with as little loss as possible. Grain-oriented electrical steel of the powercore brand from Gelsenkirchen-based thyssenkrupp plant is used among other things in distribution and power transformers, but also in charging columns for electric cars and innovative electric motors. The top grades of the powercore brand enable customers to produce transformers which comply with the EU Ecodesign Directive and contribute to reducing global energy consumption and CO2 emissions.
