BP recently announced plans to invest up to 2 billion euros ($2.12 billion) in its Spanish refinery to produce low-carbon hydrogen and biofuels through the HyVal project.
The British energy giant aims to build a large facility to produce 2 GW of green hydrogen, which is produced by splitting water using renewable energy, to replace polluting hydrogen used to produce fuels at the Castellon refinery.
The project will also triple the production of biofuels at the refinery, reaching 650,000 tonnes per year by 2030, BP said.
