METHOD OF PUMPED STORAGE Russian patent published in 2008 - IPC E02B9/00 

FIELD: construction; power industry.

SUBSTANCE: method of pumped storage includes localisation of underground pumped storage, for example identification of depth and volume of water formations or natural or commercial underground pressure-tight vessels, underground vessel pumping with water by pressure well due to either pressure created while free-flow water running in well, or when water is pumped. The hydraulic power well, which is also a water conduit, is drilled to water drain for example to culvert or water removal or absorption area. Hydraulic power well is selected so that it could cross or link with underground hydraulic storage vessel above water drain. Water level in hydraulic power well is to be above water drain, for example culvert roof or water removal or absorption area. Hydraulic power well is drilled so that it could accommodate hydraulic power set below water level or provide for hydraulic power set installing in culvert with connection to well outlet. Electrical cable or pipeline for selected energy resource transporting is installed in hydraulic power well from hydraulic power set to energy consumer. Surface water may be used for storage. Surface water is occurred during freshet periods due to, for example pressure well connection with surface ponds. This connection of hydraulic storage vessel with water drain area may be terminated in the required periods using, for example extractable packer, installed in hydraulic power well below the point of underground hydraulic storage connection.

EFFECT: potential of using water from underground hydraulic storage to generate energy resources, thermal or electrical energy.
