Nordex Electrolyzers develops 500-kW pressurized alkaline hydrogen electrolyzer designed to work with variable renewable power

### Summary of Nordex Electrolyzers’ Development of a 500-kW Pressurized Alkaline Electrolyzer

On June 17, 2024, Nordex Electrolyzers, a joint venture between the Government of Navarra and the Nordex Group, presented its first in-house-developed prototype of a 500-kW pressurized alkaline electrolyzer. This electrolyzer, designed, manufactured, and assembled entirely in Navarra, Spain, is capable of producing over 10 kg/h of hydrogen with an energy consumption of less than 50 kWh/kg.

### Key Features and Advantages

– **Variable Power Sources**: The 500-kW prototype is designed to handle power changes and frequent stops, making it ideal for using excess renewable energy.
– **Efficiency and Flexibility**: The electrolyzer has shown promising results in terms of efficiency and adaptability to renewable energy sources.
– **Integration with Renewables**: The design leverages Nordex Group’s expertise in wind turbine manufacturing to integrate hydrogen generation into its value chain.

Nordex Electrolyzers’ new prototype demonstrates significant potential in the hydrogen production sector, especially in its ability to efficiently use variable power sources, which is crucial for integrating excess renewable energy.

Nordex Electrolyzers aims to have the final design of its MW-scale product by 2026, with ongoing support from regional development agency SODENA and funding from the European Commission.
