Germany’s RWE and industrial giant ArcelorMittal have pledged to build offshore wind farms linked to hydrogen facilities to support decarbonised steel production, in a move that could advance a new collaborative approach designed to accelerate commercialisation of the green steel value chain.

The two firms intend to build a 70MW green hydrogen pilot project by 2026, with plans to expand to gigawatt scale if public funding is available, according to a memorandum of understanding signed by both. RWE and ArcelorMittal are now actively searching for sites to locate electrolysers to supply the steelmaker’s production facilities in Bremen in northern Germany and Eisenhüttenstadt on the Polish border.
