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. …

Combining thermal energy storage with buildings – a review

Thermal energy storage is not only used to reduce the energy demand, but also to shift the heating or cooling load in time. This is often called "peak shifting" or "peak shaving" and can be done according to three strategies, shown in Fig. 1.2, as discussed by Dincer [41] and He [42].Although these strategies can be used for both …
