Spain's Largest Green Hydrogen Project Underway in Castellón
Key Ideas
  • Construction has begun on Spain's largest green hydrogen project in Castellón, a 25 MW facility, creating up to 500 jobs during construction.
  • The project involves around 25 Spanish companies and aims to produce 2,800 tonnes of green hydrogen annually, replacing grey hydrogen and reducing CO₂ emissions by 23,000 tonnes per year.
  • With an investment exceeding €70 million, the plant will be operational by the second half of 2026, powered by renewable energy and meeting all EU requirements for green hydrogen production.
  • The initiative is part of Spain's Recovery, Transformation, and Resilience Plan, securing €15 million in funding, and future phases target supplying green hydrogen to industries like ceramics and heavy transport.
The joint venture between bp and Iberdrola España has initiated the construction of Spain’s largest green hydrogen project in Castellón. This 25 MW facility is expected to generate up to 500 jobs during its construction phase, involving the collaboration of approximately 25 Spanish companies. The project's first phase will focus on earthworks and site preparation on a 20,000 m² plot near the bp refinery, with civil works scheduled to commence in the second quarter of 2025. Subsequently, the main equipment, including electrolysers, will be installed in the latter part of the year. Carolina Mesa, bp’s vice president of hydrogen for Spain and new markets, expressed enthusiasm about the project, highlighting its significance in industrial decarbonisation and the transformation of refineries into integrated energy hubs. Jorge Palomar Herrero, Director of Hydrogen Development at Iberdrola, emphasized the project's contribution to the hydrogen value chain in Spain and the utilization of renewable energy from Iberdrola's wind and photovoltaic plants. The project, managed by Castellón Green Hydrogen S.L. - a joint venture between bp and Iberdrola España, involves an investment surpassing €70 million. The plant, powered by renewable energy through a power purchase agreement, is projected to produce 2,800 tonnes of green hydrogen annually, thereby reducing CO₂ emissions by approximately 23,000 tonnes per year. Additionally, the initiative secures €15 million in funding from Spain's Recovery, Transformation, and Resilience Plan, supported by the EU’s NextGenerationEU program. Furthermore, the green hydrogen plant aims to be operational by the second half of 2026, with plans to supply green hydrogen to challenging-to-decarbonize sectors like ceramics and heavy transport industries. This project signifies a pivotal step towards sustainable energy solutions in Spain, showcasing a positive outlook on the country's commitment to green hydrogen and industrial decarbonisation.
