5 August 2025 marks a remarkable milestone in the application-oriented development of our generator modules: for the first time in the company’s history, we were able to operate a micro CHP unit with hydrogen and observe its behaviour on the test bench. The success of this initial trial is particularly gratifying because we receive many enquiries from fuel cell operators. Users are looking for a robust element with continuous operating characteristics in market segments where maximum electrical efficiency is not a priority, but where the low-temperature heat generated can be put to good use, for example in heating applications.

“From operation with natural gas, we know that our alphagamma® generators already achieve two-thirds of the electrical efficiency known for fuel cells. Our current test suggests that this result can also be achieved when operating with hydrogen. This is highly motivating for us to quickly initiate the next steps in development,” say Josef Frauscher and Bernhard Spielvogel, managing directors of the company.
