Diabatic storage systems utilize most of the heat using compression with intercoolers in an energy storage system underground. During the operation, excess electricity is used to compress the air into a salt cavern located underground, typically at depths of 500–800 m and under pressures of up to 100 bars. When the stored energy is required, air is released and heated by combustion

For a coupled energy pile-solar collector system in practical engineering, the solar collectors will be mounted on the exterior walls and roofs of buildings to minimise additional land use. To avoid oversizing the solar collector area, it is important to maximise the efficiency of the solar collector through optimal design. The efficiency of the solar collector η is defined as

Underground thermal energy storage (UTES) is a form of STES useful for long-term purposes owing to its high storage capacity and low cost (IEA I. E. A., 2018). UTES effectively stores the thermal energy of hot and cold seasons, solar energy, or waste heat of industrial processes for a relatively long time and seasonally (Lee, 2012).
Underground storage systems can be used to inject and store natural gas (NG) or hydrogen, which can be withdrawn for transport to end-users or for use in industrial processes. Geological formations can additionally be used to securely contain harmful gases, such as carbon dioxide, deep underground, by means of carbon capture and sequestration
Underground thermal energy storage (UTES) is a technique for storing thermal energy that makes use of the subsurface to store both heat and cold.

Underground Thermal Energy Storage (UTES) A thermal energy storage is a system that can store thermal energy by cooling, heating, melting, solidifying or vaporizing a material , such as hot-water, molten-salt or a phase-change material. Sensible heat storage (SHS) relies on the temperature variation of a solid or liquid (e.g. water).
Underground energy storage (UES) can satisfy the seasonal peak regulation of energy fuels (e.g., oil, natural gas, hydrogen) or the peak regulation of electricity by power-to-X technology (P2X) or power-to-X-to-power (P2X2P) technology, where X stands for CO 2 , air, hydrogen, etc. (Buffo et al., 2019; Matos et al., 2019; Stančin et al., 2020).
Underground storage systems can be used to inject and store natural gas (NG) or hydrogen, which can be withdrawn for transport to end-users or for use in industrial processes.
Ibrahim Dincer, Marc A. Rosen, in Exergy Analysis of Heating, Refrigerating and Air Conditioning, 2015 Underground heat storage, or underground thermal energy storage (UTES), has storing temperature range from around 0 °C to up to 40-50 °C. This operating temperature range is suitable for heating and cooling applications in HVAC.
The site selection for underground energy storage is dependent upon several factors, mainly related to geological and engineering issues, such as: the type of candidate rocks, structural issues, tectonics and seismicity issues, hydrogeological and geothermal issues and also geotechnical criteria.
There is a need to study the gas mixtures underground for storage. The concept of underground gas storage is based on the natural capacity of geological formations such as aquifers, depleted oil and gas reservoirs, and salt caverns to store gases.
