A method, system, and apparatus including a compressed air energy storage system that includes an ambient air intake configured to intake a quantity of ambient air for storage in a compressed air storage volume, a compression system having a compression path that is configured to convey air compressed by the compression system through the compression system, a first path configured to convey ambient air to the compression system, a second path proceeding from the compression system to the compressed air storage volume and configured Io convey compressed air to the compressed air storage volume, and a dehumidifying system. The dehumidifying system is co?pleable to at least one of the first path that proceeds from the ambient air intake to the compression system, the compression path, and the second path. The dehumidifying system includes a dehumidifying component configured to remove moisture from the ambient air and/or the compressed air.
