Renewable energies: Innovative and truly Nordic

eFarm: Green energy from wind farms to hydrogen filling stations

Generating green hydrogen fuel with wind power - doesn’t work? Yes it does! This is clearly proved by the largest sustainable hydrogen mobility project to date, eFarm. In the district of North Frisia, Schleswig-Holstein, the joint project initiated by GP JOULE is implementing a hydrogen infrastructure from generation to processing and fleet use in electric vehicles using renewable energies only. The aim is to introduce a sustainable, collective system to society at large based on renewable energy. Producing, transporting, processing and marketing green hydrogen in a joint project is an ambitious undertaking that requires in-depth business and technical know-how and also the power of persuasion.


Green hydrogen from wind power - a milestone in the energy transition


The eFarm project creates a secure supply of 100 % green, regionally produced hydrogen from wind and solar power, paving the way for all citizens and companies who want to purchase a hydrogen vehicle. In order to meet the expected demand for mobility, the project comprises:


  • Five hydrogen production sites (1.125 MW total capacity) located close to existing wind farms
  • Two hydrogen filling stations in Husum and Niebüll
  • Two fuel cell buses for regular bus service
  • Thirty fuel cell cars with potential for fuelling more than 100 vehicles

The award honours committed people and outstanding projects that shape the mobility of the future innovatively, sustainably and collectively.

eFarm - Regional value creation with green hydrogen

Ove Petersen

CEO and co-founder of GP JOULE

"If people can see the connection between renewable energy production and consumption, as well as the wide-ranging benefits then they will accept the energy turnaround. To this end, eFarm will enable direct citizen participation."


Achieving acceptance through local value creation with renewable energies

By enabling citizens to experience renewable energies first-hand and participate in the regional value creation, the necessary approval for the project is created. Against this background, in addition to direct citizen participation, a project-accompanying, systematic acceptance management with the citizens is planned, which initiates a dialogue process that records in a monitoring process the extent to which the people of the region accept the project and shows their influencing factors.
