BP plans €2bn green hydrogen cluster at Castellon
Oil major unveils Hyval project to deploy up to 2GW of electrolysers at Spanish refinery complex for decarbonisation and biofuels production
BP has set out plans to develop a green hydrogen cluster with up to 2GW of electrolyser capacity at its Castellon refinery in Spain’s Valencia region by 2030. The project, called Hyval, will also include the development of biofuels production capacity and renewable power. BP says it could invest up to €2bn into Castellon by 2030. Green hydrogen generated by BP’s Castellon project will be used to replace grey hydrogen consumed by the refinery and as a feedstock for sustainable aviation fuel production. Biofuels production at Castellon is expected to increase threefold, to 650,000t/yr, by 2030. “We see Hyval as key to Castellon’s transformation and critical to supporting decarbonisation
