摘要： Disclosed techniques include energy storage and management using pumping. An energy source is connected to a pump-turbine energy management system, wherein the pump-turbine energy management system includes a pump-energy storage subsystem. Energy from the energy source is stored in the pump-energy storage subsystem. One or more processors are used to calculate a valve-based flow control setting for recovering energy from the pump-energy storage subsystem. One or more valves in the pump-energy management system are energized, wherein the energizing enables energy recovery. Energy is recovered from the pump-energy storage subsystem using a pump-turbine recovery subsystem enabled by the one or more valves that were energized. Waste heat is recovered through a waste-heat recovery subsystem which includes water heat exchangers or a fluid spray. The water from the water heat exchangers can be used to make steam or ice.

摘要： A pumped storage power plant for a temporary reversible storage of energy, such as the energy available from wind power stations and/or photovoltaic systems that is fluctuating over time. The pumped storage power plant is designed as an underwater pumped storage power plant, wherein the ocean assumes the function of an upper storage basin and a pressure tank placed on the ocean floor serves as a lower storage basin. The storage of the electric energy takes place through pumping water out of the inside of the pressure tank against the hydrostatic water pressure on the ocean floor.

摘要： An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor. The system can be integrated into various energy system sources including renewable energy such as wind, PV or thermal solar, wave, tidal, etc.
