چکیده انگلیسی
Experimental and numerical results from the world's first advanced adiabatic compressed air energy storage (AA-CAES) pilot-scale plant are presented. The plant was built in an unused tunnel with a diameter of 4.9â¯m in which two concrete plugs delimited a mostly unlined cavern of 120â¯m length. The sensible thermal-energy storage (TES) with a capacity of 12â¯MWhth was placed inside the cavern. The pilot plant was operated with charging/discharging cycles of various durations, air temperatures of up to 550â¯Â°C, and maximum cavern gauge pressures of 7â¯bar. Higher pressures could not be reached because of leaks that were traced mainly to the concrete plugs. Simulations using a coupled model of the TES and cavern showed good agreement with measurements. Cycle energy efficiencies of the TES were determined to lie between 76% and 90%. The estimated round-trip efficiency of the pilot plant was based on the measured TES performance and estimated performances of the other components, yielding values of 63-74%, which compares favorably with the usually quoted values of 60-75% for prospective AA-CAES plants.
