Large-scale renewable hydrogen production for industrial use
This pilot involves the development of a green hydrogen production facility in Melgar de Fernamental (Burgos, Spain), an area with strong solar irradiation and wind resources. The project foresees 500 MW of electrolysis capacity in two phases: 40 MW initially, followed by a 460 MW expansion. In the first phase, 25 MW (about 3,640 tonnes of renewable hydrogen per year) will be allocated to CyLH2Valley operations. Hydrogen will be mainly used for downstream green ammonia synthesis. Electricity will be supplied through a PPA from IGNIS’s renewable portfolio, supported by a 54 MW self-consumption grid connection. Water will be sourced from the Pisuerga River basin. Hydrogen will be transported by tube trailers. The site has direct motorway and rail access, enabling efficient logistics and intermodal integration.
A focused exploration of RFNBO and low-carbon hydrogen certification and its role in shaping project design and market access.
Barcelona, 15–16 October 2025 – The Castilla y León Hydrogen Valley consortium gathered in Barcelona for its second General Assembly to review progress and plan the next steps in building a clean hydrogen economy in the region.
The Regional Government of Castilla y León has begun developing the Hydrogen Strategy in Castilla y León 2030, a roadmap to position the region as a European leader in green hydrogen.
