Geothermal energy is heat energy from the earth—geo (earth) + thermal (heat). Geothermal resources are reservoirs of hot water that exist or are human-made at varying temperatures and depths below the earth's surface.
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 storage of thermal energy in boreholes is accomplished by using vertical heat exchangers buried anywhere from 20 to 300 m below the earth's surface. This facilitates the flow of heat energy into and out of the ground (clay, rock, sand, etc.) .
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.
Deeper or deep geothermal sources are often used for seasonal or large-scale energy storage. In a deep geothermal storage system, heat is extracted from rocks several kilometers underground. The deep well must be drilled to reach the high-temperature reservoirs .
