Our high-temperature fuel cell technology (HT-PEM) is at the centre of a pioneering demonstration project in Haßfurt. Together with the Helmholtz Institute Erlangen-Nuremberg (HI ERN), the Institute for Energy Technology (IfE) and Stadtwerke Haßfurt, we have succeeded for the first time in extracting high-purity hydrogen in fuel cell quality directly from the municipal natural gas network. Siqens calls this technology Electrochemical Hydrogen Separation – EHS for short.

This is what it’s all about:

  • Siqens HT-PEM stack – robust, efficient and tolerant to impurities
  • Production of up to 2.4 kg of hydrogen per day, usable for stationary applications or fuel cells
  • Local reconversion through fuel cells – ideal for balancing out solar and wind power fluctuations

With the help of Siqens EHS technology, the project partners are demonstrating how existing gas infrastructures can be utilised intelligently for the hydrogen economy. Surplus renewable electricity is converted into hydrogen, fed into the gas grid and later recovered when needed.

The project is funded by the Bavarian State Ministry of Economic Affairs, Regional Development and Energy.
