Abstract:
1. A method of using an underwater pumped-hydro energy storage device, comprising: determining, through use of an energy distribution computer, a power supply capacity of a power source and a load demand of a power user; detecting, through use of one or more sensors, a status of at least one submersible tank of the underwater pumped-hydro energy storage device; pumping water out of at least one submersible tank via a water pump to store energy when the load demand does not exceed the power supply capacity and the status of the at least one submersible tank is not empty; and generating output electrical power by permitting water to flow into the at least one submersible tank through a turbine power unit of the underwater pumped-hydro energy storage device, wherein the turbine is designed to operate at first hydrostatic pressure; and
