Interseasonal storage: a facilitator for net zero

The requirement for long term, large energy capacity storage with low utilisation is what makes seasonal storage an economic challenge. If sufficient value can be accessed through a seasonal price swing, the technology must then be able to store the volume of energy required and dispatch it at the required power capacity.

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.
