In basic research:
The unsteady characteristics of compressed air energy storage (CAES) systems was revealed. Research on the thermodynamic performance of variable-speed CAES systems, flow loss mechanisms and stress characteristics of compressors, and variable operating conditions and unsteady flow characteristics within expanders was conducted. Energy loss mechanisms across processes in coupled thermal storage and new energy systems, along with multi-scale flow-thermal-stress characteristics and influence mechanisms within high-efficiency heat storage/exchanger swere uncovered. An in-situ measurement method for thermoelectric properties of sheets, fibers, and thin films based on harmonic detection was proposed. The preparation of flexible thermoelectric devices, supercapacitors, and hydrogen storage fibers was achieved.
In key technologies:
Breakthroughs in core technologies for the 300 MW-level advanced CAES system were made, including wide-load compressors, high-load expanders, single-unit 8000 m³ thermal storage devices, and array heat exchangers; Prototypes of key components for the 300 MW-level system were developed. Key challenges in MW-scale magnetically suspended inertia flywheel system design, flywheel bodies and bearings were overcame.
In integrated demonstration:
The world's first 300 MW-level advanced CAES demonstration power station was constructed, and grid-connected operation was successfully achieved. Process design and engineering design for a highly efficient and flexible dualsupply electro-thermal system was completed, and the main equipment for demonstration systems including a 20 MWh novel spray-type packed bed was installed. The installation of main equipment for the 500 kW natural gas pressure energy recovery turbine demonstration system was finished.
In platform construction:
The “Energy Storage Testing Center of the Institute of Engineering Thermophysics, Chinese Academy of Sciences” leveraging Huairou's comprehensive instrumentation facilities was established. The development of key equipment for the “100 MW-level Advanced CAES System” at the Energy Storage R&D Center of the Nanjing Institute of Future Energy Systems was completed.
