Novel heat-transfer medium and air wall increase efficiency of solar thermal tower power plants
The higher the receiver temperature, the more efficiently a solar thermal power plant will operate. Convective thermal losses also have an important effect on yield. The HelioGLOW collaborative project by Fraunhofer Institute for Solar Energy Systems ISE and industrial partners is working to address these challenges: The project team investigated a novel ceramic heat-transfer medium including power plant design and air wall for the thermal insulation of the receiver. The trend toward continuously improving production processes is reflected in the development of the Stellio heliostat.
