Nordex Electrolyzers has designed a large 500kW electrolyzer featuring a Telergon motorized disconnector Switchgear

Nordex Electrolyzers, a joint venture between the Government of Navarra and Nordex Group, one of the world’s largest wind turbine manufacturers, inaugurated its testing facility in Lumbier last June. The company presented the first in-house-developed prototype of a 500-kW pressurized alkaline electrolyzer, which was designed, manufactured and assembled entirely in Navarra, Spain, and will be validated at Nordex Group’s facilities in Lumbier. Its objective is to produce green hydrogen as part of the European commitment to decarbonization.

Luis Solla, CEO of the company, commented: “This prototype is part of Nordex Electrolyzers’ proposed business development plan, which aims to have the final design of its serializable MW-scale product available by 2026”

Hydrogen is set to become one of the most important energy vectors of the future. Not only will it allow for better management and integration of renewable energies, reducing dependence on fossil fuels and greenhouse gas emissions, but will also allow for the decarbonization of many industrial sectors that currently require large amounts of hydrogen for their processes. Currently, this hydrogen is produced by reforming from natural gas, but the production of green hydrogen using electrolyzers is a key technology for achieving these goals.

 This prototype is capable of producing more than 10 kg/h of hydrogen with an energy consumption of less than 50 kWh/kg. Its design is intended to accommodate frequent power changes and shutdowns. This, together with the selection of suitable materials, will allow the company to differentiate its product from other manufacturers.

To complete this installation, Nordex has trusted on Telergon’s solutions to ensure adequate electrical insulation. This installation includes a switchboard with motorized disconnector, an IP65 enclosure including an S5N disconnector up to 10800 A | 1500V DC with motorized operation and bridging links to ensure adequate electrical capacity.
