Comparative experiments on a new CaCl2-based composite material and zeolite 13X inside a thermochemical heat storage reactor

Thermal energy storage includes sensible, latent and thermochemical heat storage. The latter is particularly interesting because the stored as a chemical potential, which reduces loss in long-term applications. viability of systems strongly depends on density material. development high materials thus essential to achieve compact suitable for wide range A new sol-gel composite material investigated here: it composed CaCl2 dispersed within matrix silica PEG-600 polymer. Composite containing have highest capacities seem be most promising candidates. aim develop that both efficient stable. suitability ability PEG stabilise calcium chloride prevent its deliquescence leakage. experimental results are compared those obtained using zeolite 13X, reference adsorbent
