摘要：

The innovation breakthrough in energy storage technology has become a crucial driver lor transformative and disruptive changes in the global energy landscape. It is an important measure to achieve the strategic goals of "carbon peak and carbon neutrality". In this regard, the research team on "Advanced Physical Energy Storage Technology" at Xi'an Jiaotong University has creatively proposed a new type of combined pumped-hydro and compressed air energy storage system. This technology applies air and water as the intermediate working mediums and conducts air turbine and hydraulic machinery as the power output equipment to achieve high-efficiency isothermal compression and expansion of the energy storage medium. Compared to traditional compressed air energy storage technology, the novel combined pumped-hydro and compressed air energy storage system features fast response, high efficiency, low investment cost, and so forth. Throughout the course of more than ten years of research and development, the team has completed the research on the performance and time-domain characteristics of key equipment and energy storage systems, achieved a significant breakthrough in key generic technologies of fluid machinery, and finished the development and application of life cycle assessment software for compressed air energy storage system, providing solid theoretical and data support for the large-scale promotion and application of gas-liquid hybrid compressed air energy storage technology. © 2024 Xi'an Jiaotong University.
