Apart from the photovoltaic power generation, concentrated solar power plants (CSP) are gaining importance, especially in regions with high direct radiation. For this, the Fraunhofer Energy Alliance does not only develop overall concepts but also the necessary components like heat storage technologies and concentrating optics with a focus on Fresnel collectors and absorber tubes.
The Fraunhofer Energy Alliance is researching systems for the thermal exploitation of solar energy in the areas of solar service water heating, space heating, process heat for industrial processes and solar refrigeration. To that end, researchers develop collectors and system components and design complete systems, which are tailored to the respective load profile and the available solar radiation including control units and the integration of cold and heat storages.
