Show abstract. Compressed-air energy storage (CAES) plants operate by using motors to drive compressors, which compress air to be stored in suitable storage vessels. The energy stored in the compressed air can be released to drive an expander, which in turn drives a generator to produce electricity. Compared with other energy

Abstract. A full-scale three-dimensional simulation was conducted to investigate structural response of an underwater compressed air energy storage (UWCAES) accumulator to the hydrodynamic loads at Reynolds number of 2.3 × 10 5. The accumulator was assumed to be spherical, non-distensible and fixed to the bed of a water
