  • UNDERGROUND STORAGE HEATING AND COOLING (USHC) SYSTEM
    Publication number: 20150345873
    Abstract: This disclosure describes systems and methods for the underground storage of heated or cooled fluid in order to preserve the temperature of the fluid. The systems described herein utilize one or more porosity storage reservoirs for heated or cooled fluid storage, in effect creating cold and or heat reservoirs in the subsurface. The reservoirs are hydrologically separated from the surrounding natural groundwater regime and, at least in part, thermally insulated from the natural environment by the walls creating the underground reservoirs. The walls may be actively or passively heated or cooled to provide better performance.
    Type: Application
