The management of Frauscher Motors proudly presents a delivery of Stirling generators for thermal batteries to an innovative company in the energy sector. This part of a larger order, which was completed by the end of 2024, is for the development of new solar-powered generators, which will be used primarily in countries with high levels of solar radiation all year round.

The project was triggered by the high demand for electricity in numerous data centres, which is forcing grid operators to look for alternative energy sources. Thermal batteries offer an innovative solution: These store heat, which is transferred to a storage medium using concentrated solar energy. The heat is then transferred to the Frauscher Motors via a stream of hot air, whose integrated generators produce electricity for the grid.

These innovative solar power plants differ from conventional solutions in that they can also be operated at night thanks to the stored heat.

‘We are delighted that we were able to convince our customer of the performance of our products following an international tender,’ says Josef Frauscher, Managing Director of the company. He continues: ‘In addition to optimising the gensets for the new hot air application, the challenge is to adapt the generators to the grid operator’s regulations.’
