HyBit: Decarbonization
and Sector Coupling

Together with the Oldenburg-based energy company EWE and its subsidiary SWB in Bremen, the steel company ArcelorMittal is building an electrolyser with an initial capacity of 10 MW at the Mittelsbüren power plant site (to be expanded to 300MW). Its purpose is to supply the Bremen steelworks and mobility applications with green hydrogen. ArcelorMittal is aiming for CO2-neutral steel production in Europe by 2050, and emissions are set to be reduced by 30 per cent as early as 2030. This, however, requires innovative technologies. The project "HyBit - Hydrogen for Bremen's industrial transformation", in which a group of twelve doctoral students in the Department of Resilient Energy Systems at the University of Bremen is also collaborating, is intended to implement the German government's national hydrogen strategy and support the hydrogen programme initiated by the EU Commission for the decarbonisation of large industries. The goal is to initiate a European network of hydrogen hubs that will supply the energy-intensive steel industry with sustainably produced hydrogen with the help of onshore and offshore wind energy, a maritime economic structure and ports for hydrogen imports, as well as a well-developed gas infrastructure. In the initial stage, electrolysis is now to be made commercially viable.
