Onshore Excursion Tour 2: Hydrogen in Practice(Citizens’ Energy Project, Grenzland Bürgerenergie eG, Ellhöft)
Grenzland Bürgerenergie eG was founded on 8 July 2022 in Ellhöft. Any citizen who is at least 18 years old and resides in Schleswig-Holstein can become a member of the cooperative.
By the end of March 2025, 2,138 individuals and entities had already acquired cooperative shares. The initial projects — a 5 MW ground-mounted solar installation, a 4 MW electrolysis unit, and a hydrogen filling station — represent an investment volume of approximately €17 million. To date, cooperative members have contributed about €12 million in equity capital.
On-site at Grenzstraße 1: the 250 kW electrolyzer and the hydrogen car refueling station can be seen. Several hydrogen transport bundles are prepared to meet demand in northern Germany. Under construction: a container-based hydrogen filling station and the site for the additional 4 MW electrolyzers.
The tour continues through the existing wind farm (with turbines ranging from 1.3 MW to 6.15 MW), past the sculpture site and the planned 30 MW solar field, and on to the cooperative’s 5 MW ground-mounted solar system. Right next to the access road to the solar field, a new substation is being built by Grenzstrom Bürgerwind GmbH & Co. KG. Here, electricity will be transformed from 30 kV to 110 kV. The energy will be transmitted via a 110 kV cable route to the feed-in point at the TenneT substation in Klixbüll Süd.
Next to the Ellhöft substation, a construction site for a roughly 90 MW battery storage facility is being developed. Grenzland Bürgerenergie eG will be exhibiting at Husum Wind in Hall 2.
