Abstract
We have investigated the suitability of high melting point phase change materials for use in new, large scale solar thermal electricity plants. Candidate materials for latent heat thermal energy storage are identified and their operating parameters modeled and analysed. The mathematical characteristics of charging and discharging these storage materials are discussed. Several high, melting point, high conductivity materials are shown to be suitable and advantageous for use with solar thermal electricity plants, such as Sydney University's novel, low cost Compact Linear Fresnel Reflector (CLFR) and Multi Tower Solar Array (MTSA) collector systems, as well as existing parabolic trough and tower technologies.
