Ellhöft Wind Park

Refining wind energy for more economic value

At the Ellhöft Wind Park “Bürgerwindpark Ellhöft” west of Flensburg, Germany, the community is taking decarbonization and the energy transition into their own hands. The town has been relying on wind energy since 2000. Since the expiration of the German Renewable Energy (EEG) subsidies, it is showing the way forward economically: thanks to hydrogen.

For this purpose, H-TEC SYSTEMS delivered an ME100 PEM Electrolyzer, which now converts wind power into green hydrogen. The hydrogen is used in the local transportation sector. By drying the hydrogen, H-TEC SYSTEMS enables it to be used as a fuel in accordance with ISO 14687.

A hydrogen filling station west of Flensburg distributes the hydrogen. The ME100 PEM Electrolyzer from H-TEC SYSTEMS is the key technology for refining electricity from renewable energy sources and thus opening new attractive markets without the German EEG, especially for wind turbine operators.

In total, the six wind turbines on site generate around 18 million kilowatt hours (kWh) of electricity per year. According to a study by the German Wind Energy Association, about 4000 MW of regeneratively generated electricity no longer receive EEG subsidies annually since 2021. By 2025, 2400 MW will be added annually.
