Although chemical reaction thermal storage has multiple advantages, the chemical reaction process is complex. It sometimes requires catalysers and has certain safety requirements, and there are other difficulties such as a huge one-time investment and low overall efficiency. Thus, it currently remains in the small-scale experimental stage with plenty of problems yet to be solved before any large-scale application.

The theoretical option to store energy at higher densities compared to latent heat or sensible heat storage concepts and the advantage of storing the reactants at ambient temperature make thermochemical storage systems a promising solution for longer term energy storage. On the other hand, thermochemical storage systems show a higher complexity than concepts for sensible heat storage or latent heat storage. The long-term reversibility of the reactions is an important issue. Currently, these systems are at an earlier stage of development, and there have been no commercial applications so far.
