BP & Iberdrola's Green Hydrogen Plant Advances
A joint green hydrogen plant by BP and Iberdrola in Castellón, Spain, has entered its final construction phase. The project is a landmark for European decarbonization, designed to serve heavy industries like ceramics and chemicals. It represents a key pivot from small pilot projects to industrial-scale green hydrogen deployment to tackle hard-to-abate sectors.
The Castellón Green Hydrogen S.L. joint venture is investing over €70 million into the 25 MW facility located at BP's refinery. The plant is designed to produce 2,800 tonnes of green hydrogen annually, which will initially replace the grey hydrogen used by the refinery and is expected to cut CO2 emissions by about 23,000 tonnes per year. The project utilizes a Plug Power electrolyzer and will be powered by a 200 GWh per year power purchase agreement with Iberdrola, sourcing electricity from its portfolio of Spanish wind and solar farms. Operations and performance testing are scheduled to begin in May 2026, with the plant expected to be fully operational in the second half of the year. This initiative has secured €15 million in funding from the EU's NextGenerationEU recovery fund through Spain's Recovery, Transformation and Resilience Plan. This public funding is critical as green hydrogen currently costs two to three times more than grey hydrogen, which is produced from fossil fuels. The project aligns with Spain's ambitious National Integrated Energy and Climate Plan, which targets 12 GW of electrolysis capacity by 2030. This is part of the broader EU REPowerEU strategy aiming for 10 million tonnes of domestic renewable hydrogen production and 10 million tonnes of imports by the same year. Scaling up production presents significant challenges, including bottlenecks in the manufacturing of electrolyzers and the need for massive investment in renewable energy generation to power them. The global electrolyzer manufacturing capacity is currently a fraction of what is needed to meet 2030 climate targets. Strategy consulting firms view the hydrogen market as a massive long-term opportunity, requiring between $6 trillion and $12 trillion in investment by 2050 to meet projected demand, according to BCG. McKinsey projects that green hydrogen could reach cost parity with traditional methods by 2028 in optimal regions, creating new value pools that could exceed $1 trillion by 2030.
