Spanish renewable power company Iberdrola and British oil giant BP have announced plans to collaborate on the construction of a 25-megawatt green hydrogen plant in Castellon, Spain. This initiative, boosted by a 15-million-euro EU subsidy, is geared towards assisting BP in lowering the carbon footprint of its oil refinery in Castellon. By leveraging renewable electricity sources like wind and solar power for hydrogen extraction through electrolysis, the project aligns with Europe's objectives to combat carbon emissions and enhance energy security. While both Iberdrola and BP are set to share the financing equally, the exact cost of building the green hydrogen facility remains undisclosed. This joint effort signifies a significant step in the transition towards sustainable energy solutions in the region.
