This paper presents results of engineering development for utilization of thermal energy storage (TES) for Compressed Air Energy Storage (CAES) plant applications.
Presented results include the following:
- Turbomachinery cycle optimization for TES application
- TES systems engineering and optimization
- Comparative technical and economic analysis of various CAES plant concepts with TES versus a conventional CAES plant concept
The paper concludes that utilization of TES is feasible, practical and economically attractive.
