Comparative Analysis of Isochoric and Isobaric Adiabatic Compressed Air Energy Storage

Energies, 2023
Adiabatic Compressed Air Energy Storage (ACAES) is regarded as a promising, grid scale, medium-to-long duration energy storage technology. In ACAES, the air storage may be isochoric (constant volume) or isobaric (constant pressure).

Stability analysis of a compressed air energy storage cavern transformed from a horseshoe‐shaped roadway in an abandoned coal mine

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 562-581, December 2025.
Stability analysis of compressed air energy storage caverns transformed from horseshoe‐shapes roadways in an abandoned coal mine is carried out. Both initial damage areas and two cavern shapes are numerically simulated using a one‐way coupling iteration algorithm of an improved generalization α method.
