Researched by Industrial Info Resources (Sugar Land, Texas)--Germany's steel industry is faced with the responsibility of charting the course to decarbonize steel production. ArcelorMittal (NYSE:MT) is combining the use of smart-carbon technologies with the use of hydrogen in steel production by taking a series of measures at its locations. In the first expansion phase, 100,000 tonnes of sponge iron with grey hydrogen will be generated by building a direct reduction iron plant at the Hamburg site. A demonstration plant with a 50-megawatt (MW) electrolysis unit will be built later to aid in the production of green steel. Similarly, at the Bremen and Eisenhuettenstadt sites, electrical scrap melting plants are to be constructed, to minimize CO2 emissions even further by increasing the scrap content in the pig iron.

Likewise, Thyssenkrupp-Duisburg is working on its Carbon2Chem Phase II project, for the conversion of steel mill process gases into chemical products and want to extend such solutions to other industries. In the first phase, a 2-MW alkaline water electrolyzer from thyssenkrupp Uhde Chlorine Engineers was operated in the pilot plant.

Energy company STEAG is working with Thyssenkrupp Steel for construction of a water electrolysis plant at the STEAG site in Duisburg-Walsum by thyssenkrupp Uhde Chlorine Engineers to enable the supply of green hydrogen and oxygen to Thyssenkrupp Steel's steel mill in the neighboring Duisburg district of Bruckhausen. With electrolysis capacity of up to 500 MW, the electrolysis plant could produce approximately 75,000 tonnes of green hydrogen each year.
