Seasonal thermal energy storage

Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, [1] 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. The other method, "annualized geothermal solar

Feasibility study of geothermal assisted energy storage using

This is also one of the important parameters of long-term energy storage. From the above analysis, we can find that as long as the energy storage time is sufficiently long, the geothermal energy discharged by a single cycle, the total efficiency of a single cycle, and the cumulative total efficiency will all finally decrease. 6.
