Key Findings
Nordex Electrolyzers has introduced the NX2500, a 2.5 MW pressurized alkaline electrolyzer. The system was fully designed and tested at the company’s Lumbier testing facility in Navarra, representing a milestone for domestic manufacturing in the green hydrogen sector.
Technical Details
The NX2500 is specifically engineered to convert variable renewable energy from wind and solar sources into green hydrogen. According to Nordex Electrolyzers, the system’s technical performance includes the following specifications:
- Production Rate: More than 45 kg of hydrogen per hour.
- Operating Pressure: 15–18 bar gauge.
- Energy Efficiency: The company targets stack-level energy consumption of below 50 kWh per kilogram of hydrogen.
Background & Context
The development of the NX2500 focuses on achieving closer integration with fluctuating renewable generation. By optimizing the system for variable power inputs, the technology addresses the inherent instability of wind and solar energy sources. The project has progressed through the laboratory validation phase and is now positioned for transition toward utility-scale application.
Significance & Outlook
The launch of the NX2500 marks a shift from theoretical and small-scale validation to the deployment of larger, pressurized alkaline systems. By achieving domestic manufacturing and testing in Navarra, the project demonstrates a localized capability to produce high-capacity electrolyzers capable of supporting the infrastructure required for utility-scale green hydrogen production.
