Solar power tower, Nanoparticles, Salt bath, Fluoride and Chloride
New generation of solar power towers
Light from the collecting mirrors is reflected by mirrors in the solar power tower to an insulated salt-filled tank on or under the ground. The focused light strikes a transparent fluoride or chloride salt bath containing nanoparticles. Fluoride and chloride can operate at temperatures significantly above 10000C. Most of the light enters the molten salt and is absorbed by nanoparticles within the salt. The use of nanoparticles allows controlled bulk heat absorption rather than heat absorption on a heat transfer surface. The salt bath both collects and stores the energy.
