Global wind power group Iberdrola and Swedish startup H2 Green Steel plan to build a vast renewable hydrogen plant on the Iberian peninsula to power the production of iron used to make steel with drastically reduced carbon emissions. The European Union is pushing the development of a supply chain for “green” hydrogen – made by splitting water molecules with renewable electricity – to replace the millions of tonnes of “grey” hydrogen – made with coal or natural gas – that its industry consumes every year.
