Abstract

Thermochemical heat storage is a cutting-edge technology which could balance energy usage between supplies and demands. Recent studies suggest that thermochemical heat storage has significant advantages compared to other storage methods such as latent heat storage or sensible heat storage. Nevertheless, ongoing research and development studies show that the thermochemical heat storage has some serious problems. To bring the thermochemical heat storage method into market, we introduce experimental setup with composite material using perlite that supports calcium chloride sorbent. Also, to compare thermal properties with composite material, we use pure thermochemical material. Then, we found that the composite material has higher heat storage density by mass than pure calcium chloride. Moreover, it can be regenerated easily, which was not possible in pure thermochemical materials
