Preliminary feasibility evaluation of compressed air storage power systems. Semiannual Technical Report No. 2

Technical Report ·
OSTI ID:7223435
This program involves comprehensive evaluation of technical and economic feasibility of providing low-cost, low-pollution peaking power from a modified gas turbine compressed air storage power system. Low-cost, off-peak power would compress air stored in mined, underground hardrock caverns. Subsequently, compressed air would be withdrawn, mixed with fuel, and burned and expanded through a turbine to generate peak power. The three principal technical phases require 18 months for completion. This report, phase two, involves conceptual system design studies and covers progress made during the second six months of this 18-month period. Preliminary results are presented in Part 2 for the geological surveys being conducted for Phase 1. Preliminary results for the conceptual system design studies being conducted for Phase 2 are presented in Part 3.
