Key highlights
  • Up to €211 million from the IPCEI Hy2USE programme has been approved for reallocation to Castellón by the Ministry for the Ecological Transition (through IDAE).
  • The project has also received an additional €15 million in funding through NextGenerationEU.
  • The plant is expected to begin producing green hydrogen before the end of the year and to become Spain’s largest operational green hydrogen plant in 2026.
  • The initiative involves Iberdrola España, bp and the Valencia Energy Technology Institute (ITE), and targets hydrogen use at bp’s Castellón refinery and in hard‑to‑decarbonise sectors such as ceramics and chemicals.
