大海拔高差地区固体流大规模重力储能技术
Large-scale gravity energy storage technology for solid flow in areas with large altitude differences
摘要
Abstract
The development of new gravity energy storage technologies is widespread both domestically and internationally.However,current applications of gravity energy storage are constrained by natural conditions and equipment efficiency,making it difficult to construct large-scale and high-capacity energy storage power stations.Based on China's existing resource endowments,a solid flow gravity energy storage method was proposed,which utilized naturally formed large altitude differences to construct large-scale gravity energy storage power stations,ensuring the stable operation of high-proportion new energy and new power systems.The working principle,composition structure,core technology,energy conversion,and safety and stability of solid flow gravity energy storage technology were explained.The performance parameters of several mainstream gravity energy storage technologies were compared,followed by an investment cost analysis of solid flow gravity energy storage technology under different altitude scenarios.The engineering research significance of the proposed method was clarified,along with its concept of ecological environment transformation.Although this technology is still in its initial stage,it is of great significance for promoting research in the field of gravity energy storage in China.关键词
