摘　　要：综述了热化学储能方法的基本原理及特点,并对几种有应用前景的热化学储能体系的研究现状及现存问题进行了评述,包括无机氢氧化物的热分解、甲烷-二氧化碳重整、氨基热化学储能、金属氢化物分解和水合盐分解。结果表明热化学储能方法由于储能密度高且可长期无热损储存等独特优势在太阳能热力发电、高温余热回收等大规模兆瓦级储热领域具有广阔的应用前景。同时基于热化学储能方法在实际应用中存在的诸多问题,指出热化学储能未来的研究方向。The basic principles and characteristics of thermochemical energy storage are reviewed. The research status and existing problems of several promising thermochemical energy storage systems ,including thermal decomposition of inorganic hydroxides, carbon dioxide reforming of methane, ammonia based thermochemical energy storage, as well as metal hydride decomposition and salt hydrate decomposition are discussed. Because of high energy density and long term thermal storage without heat loss at ambient temperature, thermochemical energy storage method has broad application prospects in large-scale megawatt thermal storage areas, such as solar thermal power generation, high temperature heat recovery and so on. The future research direction of thermochemical energy storage technology is also pointed out based on many problems existed in the practical application.
