The province of Castellón is preparing for a major shift in its industrial model thanks to a strategic collaboration between bp and Iberdrola. Both companies have joined forces through the joint venture Castellón Green Hydrogen to launch an infrastructure project that promises to transform the El Grau refinery into a clean energy coreThe project has just received a definitive boost with the allocation of a substantial financial sum that will allow the exploration of new ways to expand the production of this renewable gas in the short and medium term.
This capital injection, amounting to €211 million, comes at a crucial time, as the 25-megawatt plant has now completed its construction phase. With the machinery installed, technicians have begun commissioning tests to ensure that everything is working correctly. work like clockwork before the end of this year. This progress is not only good news for the companies involved, but also represents a giant leap forward for the business fabric of the Valencian Community, which sees in the green hydrogen in Spain as a real alternative to reduce their dependence on fossil fuels.
The financial backing of European funds
The Ministry for Ecological Transition, through the IDAE (Institute for Energy Diversification and Saving), has approved the reallocation of funds from the European IPCEI Hy2USE program. These 211 million euros are in addition to the 15 million euros already granted through the Recovery, Transformation and Resilience Plan. It is clear that the commitment to energy sovereignty It is a priority for the institutions, which seek to align this type of project with the EU's Accelerate EU strategy to safeguard Europe's energy independence from external markets.
What's interesting about this operation is that the financing was initially earmarked for other parts of Spain, but it was ultimately decided that Castellón was the ideal location for this investment. Thanks to this, the alliance between the oil company and the electricity company will be able to study how scale the power of the electrolyzer in future phases. Although they are currently focused on the 25 MW operational capacity, the roadmap envisions achieving much greater capacities over the next decade, even exploring the possibility of exporting surplus production to the rest of the continent.
Cutting-edge technology and emissions reduction
On a technical level, the plant uses an electrolysis process to separate water molecules using 100% renewable electricity from wind and solar farms managed by Iberdrola. This technology is expected to generate approximately 2.800 tons of green hydrogen annually, which will allow replace the use of gray hydrogen —obtained from natural gas— in the refinery processes. The environmental impact is direct and tangible: approximately 23.000 tons of CO2 emissions will be avoided annually, a figure similar to that produced by about 5.000 vehicles driving during the same period.
The project is not operating in isolation within the business sector, as it benefits from the active participation of the Energy Technology Institute (ITE) of Valencia. This collaboration ensures that innovation and technical expertise remain in the region, fostering a innovative industrial value chainFurthermore, the Castellón plant is highly likely to become the largest operational facility of its kind in Spain by 2026, which would put the province on the world map of the renewable energies applied to industry.
A breath of fresh air for ceramics and chemistry
One of the most interesting aspects of this initiative is its potential to help other sectors that are finding it very difficult to reduce their pollution. We're talking about the ceramics and chemical industries, two of Castellón's economic engines that consume enormous quantities of natural gas in their kilns and thermal processes. Green hydrogen is presented as the solution for these companies to... reduce your carbon footprint without losing competitiveness, offering them a clean fuel produced locally and reliably.
Replacing natural gas with renewable hydrogen is not only a matter of ecology, but also of economic survival in a European market that is increasingly strict on emissions. Producing it at bp's own refinery simplifies logistics and creates a more robust industrial ecosystem. In fact, the refinery's decarbonization plan is ambitious and includes other components such as... second generation biofuel manufacturing made from used oils, forming a comprehensive energy complex that looks directly to a sustainable future.
The progress of the works and the arrival of these new funds confirm that the energy transition in Castellón has gone from being a promise to a tangible reality. With the imminent launch of the first phase and an eye toward leading the sector nationally by 2026, the province is securing a leading role in the decarbonization of heavy industry. This transformation, supported by public-private collaboration and the backing of the European Union, marks the beginning of a new era where the cleanly produced hydrogen It will be the main ally in maintaining the region's industrial pulse in an environmentally friendly way.
