Abstract

The invention discloses an ocean compressed air energy storing system. According to the technical scheme, an ocean sinking box structure is adopted to realize high pressure air storage and is utilized as an energy-storing unit and is connected with a seaborne compressed air generating system through a high pressure gas pipeline, a gas storing sinking box is connected with the high pressure gas pipeline by adopting a flexible structure to overcome the displacement difference caused by sea level fluctuation, so that the depth of the sinking box structure in the ocean is not changed. The ocean compressed air energy storing system provided by the invention has the advantages that the seabed high pressure environment is utilized, the stable pressure is provided for the storage of the high pressure gas, a condition that the inner and outer pressures in a high pressure air storing container are equal is realized, the pressure applied to the wall of the high pressure air storing container is avoided, the requirement for the material intensity is reduced, the economy is improved, and the compressed air energy storing system is energy-saving, safe, clean and economical.

Description

technical field [0001] The invention belongs to the design field of compressed air energy storage systems, and in particular relates to a marine compressed air energy storage system which utilizes the pressure stability of deep-sea seawater to provide a storage environment for compressed air. Background technique [0002] Compressed air energy storage has become an important means of energy storage due to its mature technology and large-scale commercial application. However, the high-pressure gas storage container in the compressed air energy storage system has technical and technological limitations. The system has high requirements on the ability of the high-pressure gas storage container wall to withstand the gas pressure. Moreover, in order to reduce the difficulty of material selection, It is generally desired that the gas pressure in the gas tank be kept uniform and constant. The realization of these two requirements will undoubtedly increase the difficulty of gas tan...
