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.
