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.

The basic idea behind air cooling is pretty straightforward really. It works by moving regular or cooled air through those battery racks with the help of fans and some clever vent placement throughout the setup. When it comes to how heat actually moves around, we're talking about.

TES devices store energy by heating or cooling a medium (sensible heat), taking advantage of phase shifts (latent heat), or initiating reversible chemical reactions (thermochemical storage), whereas electrochemical batteries (such as lithium-ion) store energy in chemical.

Several sensible thermal energy storage technologies have been tested and implemented since 1985. These include the two-tank direct system, two-tank indirect system, and single-tank thermocline system.
