ArcelorMittal, Enagás, Grupo Fertiberia and DH2 Energy will lead development of the world's largest integrated renewable and competitive hydrogen hub in northwest Spain. Production is due to begin in 2025, with the full-sized project reaching 9.5 GW of solar power and 7.4 GW of installed electrolysers by 2030.

Amongst other uses, green hydrogen from HyDeal España will be used to make green ammonia for Fertiberia’s nearby fertiliser production plant in Avilés. This means that four out of Fertiberia’s ten Spanish production centers all have green ammonia projects in progress.

Copenhagen Infrastructure Partners, Fertiberia and Vestas will partner with Enagás (who own Spain's national gas grid) & Naturgy (a Spanish gas & electricity utility) to develop a hydrogen and ammonia mega project in the Aragon region, Spain. At full size, 5 GW of combined wind & solar generating capacity will power 2 GW of electrolysers that produce around 160,000 tonnes of green hydrogen per year. Construction of Phase I is due to start at the end of 2023, and includes plans for a state-of-the-art green ammonia production facility that will feed Fertiberia's existing fertiliser plant in Sagunto.
