Abstract

This chapter presents the relevance and integration of TES for CSP technologies. A TES system consists of the storage material, heat transfer equipment, and storage tank. The TES material stores the thermal energy either in the form of sensible heat, latent heat and thermochemical energy via chemical reactions. There are several requirements that must be considered to ensure optimal storage dynamics and longevity in a TES. These requirements are analysed and discussed. A broad spectrum of storage technologies, materials and methods are explored for the selection of suitable TES for CSP technologies. Materials for heat transfer fluid and material for energy storage that are generally used in TES are presented. Various limitations and problems of TES systems, such as high temperature corrosion with their proposed solutions, as well as successful implementations are reported. Further, storage media and storage type selection for CSPs based on their stability, material characterization and compatibility of materials are explained. Various available CSP technologies such as parabolic trough collector technology, linear Fresnel collector technology, solar tower technology, Stirling dish technology, etc., are discussed in detail and compared. Factors to be considered at different hierarchical levels for each CSP technologies with TES are explained.
