Renewable energy suffers some drawbacks such as instantaneity, instability, and the mismatch between supply and demand during the utilization. Thermochemical heat storage exhibits distinct advantages, including high heat storage density, elevated heat storage temperature, and negligible heat loss during the long-term storage. It has the capability to convert intermittent energy sources into stable moderate and high temperature heat energy to fulfill the needs of fluctuating output. The classification, basic mechanisms and characteristics of thermochemical heat storage within reaction temperature range of 400~1 100 ℃ are reviewed. Subsequently, the thermal storage performance of typical thermochemical heat storage materials, such as carbonates, hydroxides, oxides, metal hydrides, ammonia and methane are analyzed, and the structural targeted regulation and modification methods are investigated, alongside the introduction of typical demonstration projects. Following this, the reactor design and system integration of solid-gas and gas-gas reaction systems are discussed. In the last, the future research interests are deliberated and proposed in the development and industrial application of thermochemical energy storage materials.
