The structural design of axial-centrifugal combined compressor for 300 MW compressed air energy storage system, and design and manufacturing of axial flow compressor part were completed. The manufacture, integration and test of expander for 300 MW CAES system were completed, which was selected as one of the major scientific and technological innovations in the year of 2023 by the National Energy Administration and Guangming Daily. The control system debugging and low-speed test of 300 kW/10 MJ flywheel energy storage have been completed. The overall system design, flywheel parts design and manufacturing of 300 kW/320 MJ flywheel system have been completed.
In terms of integration demonstration, we completed the scheduling and operation of Zhangbei 100 MW compressed air energy storage demonstration project, which has successfully passed the acceptance of Chinese Academy of Sciences and National Development and Reform Commission. The development and procurement of Nanjing 100 MW compressed air energy storage system expander and heat exchanger equipment has been completed, which has arrived at the site of shipment. The civil site construction of the world's first 300 MW compressed air energy storage demonstration power plant as well as the processing and commissioning of key system components have been completed. These components have been delivered to the site. The manufacturing and engineering design of key components of 20 MWh new type of packed bed thermal energy storage system have been completed. The application of 500 kW/50 kWh flywheel energy storage has been completed, which successfully passed the acceptance of the pilot project of Chinese Academy of Sciences.
In terms of platform construction, based on the complete instrumentation conditions in Huairou District, the application for the establishment of "Energy Storage Testing Center of Institute of Engineering Thermophysics, Chinese Academy of Sciences" has passed the evaluation by the Institute. The manufacturing of the key equipment of 100 MW advanced compressed air energy storage system managed by Energy Storage R&D Center of ZhongkeNanjing Institute of Future Energy Systems has been completed.
