Hydrogen-based transformation of the steel industry

Hydrogen-based transformation of the steel industry


Technical Chairman

Jochen Schlüter

Seminar's target

Europe wants to become climate-neutral by 2050 and already save 55% of greenhouse gases by 2030 compared to 1990. The EU Climate Act sets these targets in law for the first time. For large parts of the European steel industry, these targets mean a far-reaching technological change. The technical solution has been found and is: Replace coal with hydrogen! But how does the new process route work in detail? What are the challenges? In three days, the seminar will provide a technical overview of the biggest technology change in the steel industry for decades.
