Thyssenkrupp Steel started testing hydrogen for use in steel blast furnaces at its Duisburg site in Germany to reduce CO2 emissions from traditional steel production using cokes. The company aims to reduce 20% of its CO2 emissions through the use of hydrogen in all three of its blast furnaces by 2022. The current tests are funded by State Government of North Rhine-Westphalia’s IN4Climate.NRW program. The project is part of the climate strategy of Thyssenkrupp towards climate-neutrality by 2050 and a next step into further commercialisation of the application. Injecting coal produces CO2 emissions, using hydrogen generates water vapor. Therefore, CO2 savings of up to 20 percent are already possible at this point in the production process. The hydrogen injection is provided by project partner Air Liquide.
