This appendix documents the work performed during the study to investigate the significance of the release of dissolved air from the water in the water shaft during air compression on the design and operation of a hydraulically compensated CAES plant. This air release phenomena has been named the Champagne Effect. Included is a description of the work performed by Dr. Mollendorf to investigate the rate of diffusion of air into water, the rate of the subsequent release of air from the water during passage up the water shaft, and an evaluation of the resulting behavior of the air bubbles in the shaft. Also included is a discussion of the dynamic modeling performed by Rowe and Associates under a separate contract to DOE. This simulation was based upon a two-fluid model of the PEPCo system and includes an analysis of potential modifications to the design that might further mitigate any operation problems.
