Research Progress on Thermochemical Heat Storage System

Thermochemical heat storage technology can store and discharge heat energy by reversible chemical reactions. It shows higher heat storage density and better long-term preservation ability than sensible heat storage and phase change heat storage, so that have a bright future in the energy application fields. According to the system configuration, thermochemical heat storage system is suggested to be divided into open and closed system. In terms of open and closed system, the crucial factors impacting on the system performance, such as heat storage materials, ambient atmosphere conditions, reaction progress optimization and reactor design, are discussed and summarized to provide some references for the development and practical applications of thermochemical heat storage system.
