Preliminary Design Study of Underground Pumped Hydro and Compressed-Air Energy Storage in Hard Rock Volume 9: Design Approaches—CAES, Appendix A: Air Storage System

摘要

This appendix documents the development of the Task 3 design approaches for the air storage system for a hydraulically-compensated, hard-rock mined cavern, Compressed Air Energy Storage (CAES) facility. The design approaches presented herein provided the basis for development of the preliminary plant design presented in Volume 12.nThe air storage system consists of a 1) surface (compensating) reservoir and intake structure; 2) air and water shafts; and 3) underground cavern. The design criteria for each has been presented in the Project Design Criteria -CAES, Volume 3. On the basis of those criteria, the design approaches for each are discussed in this appendix.
