Solar Thermal Micro-turbine


Development of a technology for a descentralized electric current generation from solarthermic energy in a power range up to 20 kW. For this, compressed wind in an absorber tube becomes heated through solar energy. The absorber tube is located in the focal point of a parabolic trough, as it is known among the solar thermal big energies. After the compressed air in the absorber is heated, is it released in a micro-turbine in order to count with electric current. At the same time, a compressor on top of the turbine produces new compressed air, which is heated in the absorber. Because of the fact that the core components of the Solar Thermal Micro- turbine (turbine, generator and heat exchanger) are installed on the floor, it is possible to integrate a heavy heat accumulator in order to produce current at night too.

Development stage, time to market

Market potential

State of development: Basic research and concept development are finished. Development of the gas turbine components is being developed.

Time to market: in the next 12 months

Market size and characteristics

Markets in countries with public grants for regenerative energies (e.g. Germany, Spain, Switzerland) Potential markts in areas where a poor developed infrastructure without electricity network are present, and where there is sufficient sunlight. (e.g. arabic, african and sudamerican regions).

Approx.. 2 bn people have no access to public electricity networks, thereof approx. 30% are able to procure an electricity generator equipment. Out of these, 0,7 bn people, there are a 1% resdy to buy a solar turbine

market volume of 210 bn Euro by an equipment price of 30.000 Euro.


Partnering sought

We have some potential customers in Spain, Germany, Italy
