The mobilized thermal energy storage （M-TES） technology can make the ＂when＂ and ＂where＂ of waste heat＇s availability match the ＂when＂ and ＂where＂ of its reuse, which is very attractive. This paper presented a review on the research progress of M-TES technology, and the distributed heat user market in our country was also analyzed. The advantages and disadvantages of the energy storage technology such as chemical energy storage, sensible heat storage and latent heat storage which can be used for the M-TES were also discussed. The latent heat thermal energy storage has the advantages of flexibility, high efficiency and stable heat supply, which is very suitable for mobile heat storage car. The phase change materials （PCMs） to be used for heat source at different temperatures were summarized. Various heat transfer enhancement methods were reviewed and discussed to solve the problem of the low thermal conductivity of the PCMs. What we need to do to promote the M-TES technology was pointed out. And finally the market application of the M-TES technology was prospected.
