eFarm North Frisia

Sector integration for regional value creation

Green hydrogen is the decisive building block for the energy transition in all sectors. Whether mobility, industry or heat: In Germany's largest hydrogen mobility project "eFarm", H-TEC SYSTEMS demonstrates how the energy transition with PEM electrolysis works.

The hydrogen network eFarm in the district of North Frisia (Schleswig-Holstein, Germany) uses a total of five H-TEC SYSTEMS ME100 electrolyzers, each of which can produce up to 100 kg of hydrogen per day from drinking water and electricity. The nominal load is 225 kW each. The energy source is surplus, regionally generated electricity from wind turbines.

The electricity is converted into hydrogen by PEM electrolysis, then stored on-site in pressure tanks, and regularly transported by pressure tanker to two hydrogen filling stations. Here, the hydrogen is available for fuel cell vehicles in local public transportation as well as for private customers. 

The PEM electrolyzers also make it possible to use the waste heat from the process. In the case of eFarm, it flows into the regional heating grid for industry and private households. In this way, the H-TEC SYSTEMS electrolyzers achieve an efficiency of up to 90 percent or more. The annual CO₂ savings amount to approx. 322 t/bus (public transport) plus a further 800 t due to using the process heat.

The goal of the eFarm project is to bring a sustainable economy into society at the community level. In addition to technical and business knowledge, this project has required the power of persuasion as well as the support of the community.
