COADUNATION OF TECHNOLOGIES - COGENERATION AND THERMAL-ENERGY STORAGE

Thermal energy storage can help cogeneration meet the energy generatio n challenges of the 21st century by increasing the flexibility and per formance of cogeneration facilities. Thermal energy storage (TES) allo ws a cogeneration facility to: (1) provide dispatchable electric power while providing a constant thermal lend, and (2) increase peak capaci ty by providing economical cooling of the combustion turbine inlet air The particular systems that are considered in this paper are high-tem perature diurnal TES, and TES for cooling the combustion turbine inlet air. The paper provides a complete assessment of the design, engineer ing, and economic benefits of combining TES technology with new or exi sting cogeneration systems, while also addressing some of the issues i nvolved.
