Geothermal Energy Storage is explored as a key strategy for large-scale storage of renewable energy. Effective or improved energy conservation is essential as energy needs rise. There has been a rise in interest in using thermal energy storage (TES) systems because they can solve energy challenges affordably and sustainably in various contexts.
Shallow geothermal energy is stored in the Earth's uppermost layers, up to a few hundred meters deep, and can be extracted using a geothermal heat exchanger or ground source heat pump (GSHP). The heat exchanger paced 1 to 2 m below the surface from the shallow geothermal energy.
The Geothermal Energy Storage concept has been put forward as a possibility to store renewable energy on a large scale. The paper discusses the potential of UTES in large-scale energy storage and its integration with geothermal power plants despite the need for specific geological formations and high initial costs.
Short History of Shallow Geothermal Energy The earth offers a steady and incredibly large heat source, heat sink and heat sto-rage medium for thermal energetic uses, like for the geothermal heat pump. A steady temperature in the underground first was scientifically proven in deep vaults beneath the Observatoire in Paris.

ABSTRACT Geological thermal energy storage (GeoTES) utilizes underground reservoirs to store and dispatch energy per a given demand schedule that can span entire seasons.
Installed thermal capacity of direct geothermal energy utilization for different regions worldwide (data from Lund and Toth 199, excluding heat and cold storage through aquifer thermal
These proposed systems combine established energy generation and storage technologies in innovative ways, unlocking long-term storage potential of geothermal and creating
The shallow depth artificial reservoir (also called shallow depth enhanced geothermal system, SDEGS for short) has no special requirement to temperature, depth and storage space for water, and thus
The temperature in the ground can also be changed artificially by storage of heat (e.g. from waster heat or solar heat) or cold, creating an Underground Thermal Energy Storage System
• Aquifers serve as versatile thermal reservoirs, acting as both heat sources and sinks for diverse heating and cooling needs. • Geothermal Energy Storage is explored as a key strategy for
