Major Progress and Achievements in 2013
In terms of novel energy storage technology based on air, the center has completed a 1.5 MW supercritical air energy storage system experiment platform and has begun conducting experiments. The projects have passed the acceptance inspection by the Beijing Municipal Science & Technology Commission with results reaching or exceeding the standard. A running test of more than 500 hours of smooth operation has shown the system achieving primary requirements, demonstrating the success of experimental verification of the supercritical air energy storage system. The center has completed the systematic design and experimental platform construction of the energy storage system combining compressed fluid with compressed gas. Research has been carried out on modeling and the evaluation of the system, and conducting a series of experiments obtaining promising results.
The center has completed the parameter selection, system design, and components’ investigation of the key devices for the 10 MW supercritical compressed air energy storage system. This includes compressor chains, expander chains, heat and cold storage tanks and so on. Based on the 10 MW compressed air energy storage system, an economic evaluation model has been proposed and economical analysis has been made on the system applied to the fields of wind power and off-peak electricity pricing.
As for research on systems for cold and heat storage and material, the center has finished the manufacture, installation and debugging of key devices of a 10 GJ high pressure cold storage exchanger and subcritical water heat storage subsystem used in the 1.5 MW advanced air storage system. Also the Centre has completed the design, investigation and selection of the heat storage subsystem of the 10 MW advanced air storage system, including cooling storage tanks, heating storage tanks and heat exchangers. A series of studies have been conducted on the heat and cold storage technology in the cascade packed bed, subcritical water heat storage technology, latent functionally thermal fluid heat storage technology, the technology of heat storage in a spray packed bed, medium-high temperature heat storage technology, and particle fluidized heat storage technology. Numerical calculation and experiments have been made and certain results have been obtained.
With regard to micro pumped-hydro energy storage systems, the center has finished the updating of the key equipment, adding a video surveillance subsystem and hydraulic pump/motor volumetric efficiency measuring equipment and finally conducted a series of systematic cycle tests.
Thirty papers were published in 2013, including 14 indexed by SCI, 8 by EI, 3 specially invited lectures at international conferences, and 3 oral presentations at international conferences. Fifteen national invention patents and 14 utility model patents were applied for, and 1 national invention patent and 10 utility model patents were authorized. The center chaired or co-compiled 3 strategy/ policy research reports including Electric Power Development, the Twelfth Five-year Plan for National Energy Storage, Energy Storage Science and Technology for Energy Storage Industries Study 2013 and 1 monograph. The Research Report on the Urban Energy Consumption Methods in China we co-compiled has won the second prize for soft science awarded by the National Energy Administration.
