Green Hydrogen Project Expands in Galicia Through New Alliance
Three energy and industrial groups have unveiled a new alliance aimed at accelerating renewable hydrogen production in Galicia. The collaboration brings together Reganosa, alongside a partner group focused on improvisation and development, to establish a renewable hydrogen production facility on land formerly occupied by the Meirama coal plant in Cerceda, a municipality in A Coruña. The project signals a notable step in the region’s shift toward clean energy and is positioned to contribute to local decarbonization efforts while stimulating regional economic activity.
The initial phase of the plant will generate electricity from renewable sources and produce green hydrogen with no greenhouse gas emissions. The plant’s starting capacity is planned at 30 megawatts (MW), with a staged expansion designed to reach a total potential of 200 MW. The three companies estimate that the project can yield more than 4,000 tons of renewable hydrogen per year during the early phase, scaling up to a target of 30,000 tons annually as operations mature. This growth trajectory reflects a deliberate plan to match demand across multiple sectors.
Once produced, the renewable hydrogen is expected to serve several crucial applications. A primary objective is to replace conventional hydrogen currently used by the Repsol refinery in A Coruña, reducing the refinery’s carbon footprint. In addition, the hydrogen will be injected into the gas grid to blend with natural gas, enabling broader decarbonization of energy supply. The project will also support multiple industries pursuing sustainable mobility solutions, including transportation and logistics sectors seeking lower-emission fuel alternatives.
From the outset, the project team emphasizes that innovation will occur across the entire value chain. This encompasses the production facility itself, the deployment of hydrogen in industrial processes, the injection of hydrogen into the gas network, and the commercialization of green gases through guarantees of origin. The work will draw on standardized sources for renewable gases (GdOs) and will explore their use in sustainable mobility programs, ensuring traceability and reliability for downstream users. The initiative thus represents a holistic approach to growing a green hydrogen ecosystem that connects generation, infrastructure, and end-use markets.
The undertaking arrives amid broader policy and market momentum around hydrogen as a clean energy vector in Europe and specifically within Spain. Local authorities and participating firms view the Cerceda project as a practical demonstration of how green hydrogen can be integrated into existing industrial facilities while expanding renewable energy generation capacity in a way that supports regional energy security and economic resilience. As plans advance, ongoing assessments will monitor environmental impact, supply chain readiness, and regulatory alignment to ensure the project can scale safely and efficiently.
In commentary on the collaboration, representatives from the three groups highlighted the importance of cross-sector cooperation. By aligning production, infrastructure, and market development, the alliance aims to establish a reliable domestic pathway for renewable hydrogen that could serve as a model for similar initiatives elsewhere in Spain and beyond. The partners also noted that investments in advanced electrolysis technologies, storage solutions, and hydrogen-ready infrastructure are essential to achieve the projected growth and to deliver measurable emissions reductions in the near term. This project thus positions Galicia as a potential hub for green hydrogen in the Iberian Peninsula, with downstream benefits spanning industry, mobility, and energy supply.
