Materials for Thermal Energy Storage: Characterization

This chapter focuses on the experimental characterization techniques commonly employed to get a deep understanding of the thermal energy storage (TES) materials properties. In particular, experimental methodologies available to characterize thermophysical parameters qualifying both thermodynamic and dynamic performance of TES materials are discussed, trying to highlight pros and cons. The analysis is performed for the three TES categories, sensible, latent and thermochemical, representing a contribution toward the proper selection of experimental techniques at material level.
