In many studies, regions of high geothermal gradient were considered, involving high porosity and high permeability with large mass rocks which tend to be heterogenous in nature, however it is
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.
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 .
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.
Discussion on the nontechnical aspect such as policy and regulations as well as community awareness will also be outlined and discussed. Rocks thermal energy storage is one of the most cost-effective energy storage for both thermal (heating/cooling) as well as power generation (electricity).
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.) .
