The joint venture Nordex Electrolyzers — backed by Sodena (the public investment company of the Government of Navarra) and Nordex Group — has unveiled the NX2500 at its test facility in Lumbier, recognised as the largest electrolyser fully designed and manufactured in Spain.
Innovation and local production
The NX2500 is a pressurised alkaline electrolyser with a nominal power of 2.5 MW, capable of producing over 45 kg/h of green hydrogen using renewable energy (wind or solar). Designed, assembled and tested in Navarra, it represents the third milestone in the company’s technological roadmap, which aims to reach 5 MW and 10 MW modules by 2026.
A key step in the energy transition
Thanks to its modular and scalable design, the system allows multiple units to be combined for higher-capacity configurations. Its deployment in energy-intensive industries is expected to avoid thousands of tonnes of CO₂ emissions each year. This technological breakthrough strengthens Navarra’s position as a strategic hub in Europe’s green hydrogen value chain.
Public-private collaboration and regulatory framework
Nordex Electrolyzers’ initial investment amounted to €30 million, including €12 million in European funding through the IPCEI Hy2Tech programme. During the presentation event, representatives from the Government of Navarra and the company discussed the need for a clear regulatory framework to accelerate the industrialisation of green hydrogen in Spain.
Relevance for investors
For investors and companies looking at Navarra as a location for energy transition projects, this development demonstrates:
- A tangible example of local R&D and advanced manufacturing.
- Industrial infrastructure ready for emerging technologies.
- Active collaboration between public, private and European partners.
- Access to a growing hydrogen value chain with export potential and global impact.
