Abstract: Salt hydrates based phase change materials (PCMs) have a number of advantages such as high energy density, high thermal conductivity, moderate phase transition temperature and low price, making the materials promising candidates for numerous potential applications and hence a hot research topic over the past decade. This paper reviews and analyses the state-of-the-art development of the salt hydrate based PCMs and summarizes the progress in the thermophysical properties and applications of the materials. Main challenges in the industrial uptake of the salt hydrates based PCMs are supercooling, phase separation and corrosion. The progress and methods in resolving these challenges are discussed. Finally, recommendations are given for further research and applications of the salt hydrates based PCM.

Key words: salt hydrate, heat storage, phase change materials, stability, corrosion
