Spanish energy giant Iberdrola and UK-based oil and gas company BP have received approval to construct a 25 MW green hydrogen plant in Castellón, Spain. The project, part of their joint venture Castellón Green Hydrogen S.L., will receive €15 million funding from Spain’s Recovery, Transformation and Resilience Plan. The plant is planned to house a 25 MW electrolyzer and convert 200 GWh of renewable energy from Iberdola’s photovoltaic and wind projects into approximately 2,800 mt of green hydrogen annually. This move is projected to reduce emissions by 23,000 mt per year. Moreover, the green hydrogen production may replace grey hydrogen derived from natural gas at the refinery, transforming BP's Castellón facility into an integrated energy hub. BP also aims to explore the possibilities of expanding green hydrogen production capacity and utilizing green hydrogen in challenging-to-decarbonize industries in the Valencia region. This initiative marks a significant stride towards sustainable energy practices, aligning with the global shift towards green energy and decarbonization efforts.
