Project SFERA-III: Fraunhofer ISE offers Access to CSP Research Infrastructures

Concentrated solar radiation is a very promising renewable energy resource. The best known application is electricity generation in Concentrated Solar Power (CSP) plants, but other applications have also been demonstrated, such as production of solar fuels, water treatment and research in advanced materials. Europe is a leader in research and development of this technology. In line with this development, the European Union is promoting the opening of key Research Infrastructures (RIs) in solar concentrating systems for both academia and industries for carrying out energy and materials research as well as research in other fields using the extreme temperature conditions in solar concentrators. Within the ‘Solar Facilities for the European Research Area Third Phase (SFERA-III)’ Project, the Fraunhofer Institute for Solar Energy Systems ISE provides access to its laboratories.
