Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar collectors or waste heat from air conditioning equipment can be gathered in hot months for space heating use when needed, including during winter months.

Seasonal thermal storage is an extremely promising technology for saving energy, yet the cost is currently too high to be acceptable for most people, even by using the sensible storage concept. Among all the available technologies, chemical heat storage is regarded as the idea with greatest potential in the long run due to its high energy density.
