UTES (Underground Thermal Energy Storage) aims to answer this question and such systems could contribute to the heating and cooling of individual homes or several buildings. A first option is an open-loop system: ATES (the A stands for aquifer). Water is extracted from an aquifer located at a depth of between 40 and 300 metres; in summer, the
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) cause of high thermal inertia, the
The proposed technology, called Underground Gravity Energy Storage (UGES), can discharge electricity by lowering large volumes of sand into an underground mine through
This article suggests using a gravitational-based energy storage method by making use of decommissioned underground mines as storage reservoirs, using a vertical shaft and electric
"The HOT Energy Group has substantially assisted RAG in planning almost all of our underground gas storage (UGS) facilities. The quality of their subsurface models has proved outstanding and has helped us to develop more than 50% of our gas fields into successful UGS operations and to become one of Europe''s leading gas storage operators."
Underground Thermal Energy Storage is well suited to district energy systems, where thermal energy is transferred trough piping networks for heating and cooling. Adding a thermal energy store increases the thermal capacity of district energy systems, improves energy efficiency and resiliency and benefits system operators and users.
3.2 Impact of Hydrogen Transition on Underground Energy-Storage Reserves. Assuming pure CH 4 storage, the current cumulative WGE of UGS facilities in the U.S. is 1,282 TWh. We estimate that transitioning working gas from CH 4 to pure (i.e., 100%) H 2 nationwide would reduce the cumulative WGE by 75%–327 TWh (Table 1). A reduction in energy
Underground thermal energy storage (UTES) provides large scale (potentially >10 GWh) storage capacity per site that is difficult to achieve with other heat storage technologies, and benefits from a typically lower range of storage costs (Persson et al.,2014).

Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean energy, enable a strategic petroleum reserve, and promote the peak shaving of natural gas. Rock salt formations are ideal geological media for large-scale energy storage, and China
Compared with aboveground energy storage technologies (e.g., batteries, flywheels, supercapacitors, compressed air, and pumped hydropower storage), UES technologies—especially the underground storage of renewable power-to-X (gas, liquid, and e-fuels) and pumped-storage hydropower in mines (PSHM)—are more favorable due to their
