The joint venture (JV) between BP and Iberdrola España – Castellón Green Hydrogen S.L – has announced that its 25 MW green hydrogen project, which will be the largest operating project in Spain, has reached 90% completion of its assembly phase with all the equipment on site, including the electrolyser system supplied by Plug Power. Around 25 Spanish companies are involved in the construction of the plant.
The commissioning period, which includes testing to monitor the operation and performance of the equipment, is scheduled to begin in May 2026.
This milestone reinforces BP and Iberdrola España's leadership in the green hydrogen sector in Spain, an energy vector that has the potential to play a significant role in the decarbonization of industry.
Julio Castro, CEO of Iberdrola Energía Sostenible España, part of Iberdroola España, said: “This project is a tangible example of industrial electrification, which reduces CO2 emissions and strengthens energy security. This plant will be powered by 200 GWh/year of renewable energy from our wind farms and photovoltaic plants in Spain”.
For her part, Carolina Mesa, VP Hydrogen, Europe & MENA at bp, said: “These developments are great news for the Spanish energy sector. They reflect tangible progress in a key industrial decarbonisation project and consolidate BP's refinery in Castellón as the benchmark in the country.”
The project has an investment of more than €70 million and is being developed jointly by bp and Iberdrola España through Castellón Green Hydrogen S.L., a company equally owned by both companies.
The 25 MW electrolyser will be powered by renewable electricity through a power purchase agreement (PPA) supplied by Iberdrola España from photovoltaic and wind farms. The production of 2,800 tonnes of green hydrogen a year is expected to replace part of the grey hydrogen currently used by the refinery in its processes and is expected to prevent the emission of approximately 23 000 tpy of CO2, equivalent to the CO2 production from 5000 cars over the the same period.
This initiative, with the participation of the Instituto Tecnológico de la Energía (ITE), has obtained funding equivalent to €15 million from the Innovative Value Chain and Renewable Hydrogen Knowledge support programs of the Spanish Recovery, Transformation and Resilience Plan, with funds allocated by the European Union's NextGenerationEU.
BP and Iberdrola España continue to explore opportunities to increase green hydrogen production at the Castellón refinery.
