Thermal energy storages are applied to decouple the temporal offset between heat generation and demand. For increasing the share of fluctuating renewable energy sources, thermal energy storages are undeniably important. Typical applications are heat and cold supply for buildings or in industries as well as in thermal power plants.
Thermochemical heat storage is a technology under development with potentially high-energy densities. The binding energy of a working pair, for example, a hydrating salt and water, is used for thermal energy storage in different variants (liquid/solid, open/closed) with strong technological links to adsorption and absorption chillers.
Underground thermal energy storage (UTES) UTES refers to the various systems that use natural subsurface locations to store thermal energy (Fig. 1). UTES is a system that has been utilized to store vast quantities of heat energy throughout several seasons to provide air preheating, ventilation, space cooling, space heating, and process cooling.
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.
Sensible, latent, and thermochemical energy storages for different temperatures ranges are investigated with a current special focus on sensible and latent thermal energy storages. Thermochemical heat storage is a technology under development with potentially high-energy densities.
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.
