Abstract

The application scenarios and site selection range of compressed air energy storage (CAES) can be effectively expanded through underwater air storage

which provides large-scale

long-term energy storage support for the exploitation of deep-sea and far-offshore wind power resources and the construction of large-scale integrated hydro-wind-solar-storage new energy bases. Firstly

the technical principles and application scenarios of underwater compressed air energy storage were introduced

and the characteristics of constant pressure and complete inflation/deflation of underwater air storage

along with its advantages of high efficiency

flexibility

and safety

were analyzed. Then

an experimental setup utilizing a pressurized water tank was constructed to simulate the underwater environment. The deployment time and energy conversion efficiency of underwater flexible air storage bag were analyzed through experimental tests and theoretical calculations conducted on different water bodies

including seawater

lake water

salt lakes

and reservoirs. Results indicate that

for air storage bag

the deployment time is longer and the energy storage capacity is higher in water bodies with higher density. The energy conversion efficiency during the compression process increases with the rise in water density

the increase in underwater temperature

the decrease in ambient air temperature

and the increase in water depth.
