Our 14th SEC technology tour took us to the ThyssenKrupp steelworks in Duisburg on September 23, 2024. Almut and Peter Staniek organized the tour; thank you very much for that! Details can be found in the invitation, which was sent to all SEC members and the surrounding JCF regional sections in June 2024. As with the Freudenberg tour to Weinheim, our invitation was gladly accepted. Nearly 40 SEC and JCF members learned about current steel production and decarbonization using hydrogen as a reducing agent (green steel).
