Affected by weather and environmental changes

there is an intermittent supply problem in solar thermal power generation system. The proposal of thermochemical energy storage provides a solution to this problem. In this paper

the thermochemical reaction characteristics of metal oxides and perovskite as energy storage medium and the influence of reactant structure on the reaction are reviewed. The results show that

the redox cycle reaction energy storage of metal oxides and perovskites has a series of advantages

such as high energy density

stable energy storage and low energy loss

which are suitable for solar thermal power generation. Meanwhile

there are technical and economic problems in the process of practical application and transformation because of the immature technology. This paper points out that the main research directions are the research on the redox reaction cycle performance of reactants

the simulation in the process of heat storage/release

the design of energy storage system and a certain scale of experimental research in the future.
