Water and gas compartment energy storage system

Abstract

The invention discloses a water / gas chamber energy storage system and relates to a physical electric energy storage system. The system comprises an air compressor pump group, a high-pressure gas chamber, a high-pressure water chamber, power generation / energy storage devices and a water storage chamber, wherein the high-pressure gas chamber and the high-pressure water chamber are independently arranged; the water storage chamber is communicated with atmosphere; the air compressor pump group is communicated with the high-pressure gas chamber through a first pipeline; a first valve is arranged on the first pipeline; the high-pressure gas chamber is communicated with the high-pressure water chamber through a second pipeline; a second valve is arranged on the second pipeline; and at least one power generation / energy storage device is arranged between the high-pressure water chamber and the water storage chamber. By the simple structure, the energy is converted, the construction cost of the system is reduced, and the problems that the traditional compressed air energy storage system is high in construction cost of equipment and complex in heat exchange systems are solved. In addition, due to the high-pressure gas chamber and the high-pressure water chamber which are independently arranged and communicated with each other, the output of gas pressure is controllable, the output of water pressure is controllable, and the output power of generators / motors is controllable.

Description

technical field [0001] The invention relates to a physical energy storage system for electric energy, in particular to a water-gas sub-compartment energy storage system. Background technique [0002] China has surpassed the United States to become the world's largest energy consumer. In the future, with China's rapid development, energy consumption will increase significantly. my country will bear more and greater burdens in energy consumption, energy conservation and emission reduction. international pressure. [0003] At present, the mainstream trend of world energy development is undergoing major changes, and is gradually moving towards the road of abandoning nuclear power and hydropower. For example, Germany, the core country in Europe, has announced that it will abandon nuclear power in 2020, and other European countries have blown up expired hydropower stations; With energy utilization, gradually increase the proportion of emerging energy and renewable energy in the gr...
