Conventionally, metal hydrides have been explored for their application in hydrogen storage systems. However, metal hydride based thermal systems have attracted huge attention for a wide variety of applications such as thermal storage, hydrogen compression, heating, cooling, etc due to the availability of hydride materials covering a wide range of operating temperatures and pressures. These can deliver high energy densities leading to compact systems for stationary as well as mobile applications. Moreover, the thermal properties of hydrides can be tailored by tuning the proportion of constituent metals to fit the required thermal application. As metal hydride based thermal systems are identified as potential candidates for global energy needs, it is essential to understand their modes of operations and the status of their development. This paper presents a comprehensive review of theoretical and experimental studies on thermal applications of metal hydrides which include refrigeration, heat transformers, heat pumps, and thermal energy storage. Also, hydride selection criteria for specific applications and heat transfer augmentation techniques adopted to improve the performance of hydride beds are discussed.
