Pumped Storage Hydropower. High efficiency in energy storage and release, especially during peak electricity demand. Higher capital cost due to construction of reservoirs and dams, but cost-effective in long-term energy management. Potential impact on ecosystems and water flow, but generally lower than fossil fuels.
The Geothermal Battery Energy Storage concept allows nearly all the stored heat to be practically recovered, after the reservoir is adequately thermally charged, even for permeability variations. Bottomhole pressures, however, tend to show somewhat greater variations during production and injections for permeability variations.

Abstract. The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s. Hydro power is not only a renewable and sustainable energy source, but its flexibility and storage capacity also make it possible to improve
In addition, electricity could be generated by installing power plants near areas containing rocks with radioactive materials that constitute high-energy reservoirs [28], [29]. Another essential heat source is found at depths of 3–10 km beneath the earth''s surface, formed by high heat production granites or hot dry rock (HDR).
In this table, electrical generation capacity (MW) and energy storage capacity (MWh) data were obtained from external sources, whereas the capacity of the upper reservoir of each PHS system, energy storage capacity (JRC) and storage hours were calculated by the GIS model or from its sources.
