• Spain has approved the reallocation of up to €211 million ($240 million), in IPCEI Hy2USE funding for the Castellón green hydrogen project.
• BP and Iberdrola have completed construction of a 25MW green hydrogen plant at BP’s Castellón refinery.
• The project could support decarbonization in refining, ceramics, chemicals, and other hard-to-abate industrial sectors.

Spain Backs Castellón Hydrogen Hub

BP and Iberdrola have secured a major funding boost for their green hydrogen plans in eastern Spain, after the country approved up to €211 million, or about $240 million, for the Castellón project.

Spain’s Ministry for the Ecological Transition and the Demographic Challenge approved the reallocation through the Institute for Energy Diversification and Saving, known as IDAE. The funding comes from the Important Project of Common European Interest Hy2USE program.

The approval gives fresh momentum to one of Spain’s most advanced industrial hydrogen projects. It also places Castellón within Europe’s wider effort to cut dependence on imported fossil fuels.

Iberdrola España and BP are developing the project through their joint venture, Castellón Green Hydrogen S.L. The partners have already completed construction of a 25MW green hydrogen plant at BP’s Castellón refinery. The facility has now entered commissioning tests.

The plant is expected to begin producing green hydrogen before the end of this year. Under current plans, it could become Spain’s largest operational green hydrogen facility in 2026.

Funding Targets Industrial Decarbonization

The Castellón project is designed to replace natural gas in industrial processes with renewable hydrogen produced in Spain. That is central to the project’s strategic value.

For BP, the refinery offers a direct industrial use case. Green hydrogen can help lower emissions from operations that remain difficult to electrify.

For Iberdrola, the project fits its wider renewable power strategy. It also strengthens the company’s role in linking clean electricity with industrial demand.

The project could also support other hard-to-abate sectors in the Valencian Community. Ceramics and chemicals are among the industries identified as potential users of green hydrogen from the facility.

That matters for Europe’s industrial base. Many companies face pressure from carbon pricing, customer demands, and future emissions rules. Access to lower-carbon inputs could become a competitive factor.

The Energy Technology Institute of Valencia is also participating in the project. Its involvement adds a regional technology and innovation component to the industrial plan.

EU Policy and Energy Security Drive Demand

The funding approval aligns with Europe’s broader push to accelerate clean energy deployment. The initiative is linked to the EU’s ACCELERATE EU package, which aims to support decarbonization and strengthen energy supply independence.

For policymakers, green hydrogen remains a priority because it can serve sectors where direct electrification is limited. It can also support energy security when powered by domestic renewable energy.

The Castellón project has also received €15 million from Spain’s Recovery, Transformation and Resilience Plan. That support comes through programs for the Innovative Value Chain and Knowledge in Renewable Hydrogen. The funding is backed by the European Union’s NextGenerationEU program.

Together, the funding streams show how public finance continues to shape the hydrogen market. Many green hydrogen projects still face high capital costs, uncertain demand, and infrastructure gaps.

Public support can reduce those barriers. It can also help create early operating projects that prove commercial and technical models for larger deployment.

What Executives and Investors Should Watch

The Castellón project gives corporate leaders a clear signal about Europe’s hydrogen priorities. Governments are directing capital toward projects tied to industrial use, regional jobs, and energy independence.

For investors, the key question is whether early hydrogen hubs can move from subsidy-backed pilots to scalable commercial platforms. Demand from refineries, chemicals, ceramics, and heavy industry will be critical.

The project also highlights the importance of partnerships. BP brings an existing industrial site and hydrogen demand. Iberdrola brings renewable power expertise and a broader electrification strategy. Regional technology partners add local capability.

That structure may become a template for other European hydrogen projects. Industrial clusters can reduce offtake risk, while public funding can support the first wave of deployment.

Spain’s approval does not remove the wider challenges facing green hydrogen. Costs remain high, and infrastructure is still limited. However, Castellón now has policy support, financing momentum, and a near-term operating timeline.

For Europe, the project carries significance beyond one refinery. It points to how clean power, industrial policy, and energy security are converging. If successful, Castellón could become an early test case for hydrogen’s role in cutting emissions across Europe’s industrial regions.
