Characterization of materials for sensible thermal energy storage at high temperature

Abstract

Among the several materials that can be appropriate for thermal energy storage (TES) application, this study focuses on sensible heat storage technology. In particular, are selected the common used materials at high temperature, molten salts and concrete. The aim is to define the key parameters and characterization techniques that determine the suitability of the material for TES. Broadly, in both materials thermo-physical and mechanical properties are evaluated. In the characterization of these materials highlights the procedure and equipment used to measure the specific properties. Mainly, the testing depends on the required sample size and operating temperature to be achieved. This chapter is based on the characterization carried out in previous researches as well as to define these thermal and mechanical techniques properly.
