This paper presents the results of a project targeted at developing cost effective power plant concept with integrated Coal Gasification System (CGS) and with Compressed Air Energy Storage (CAES) plant. The developed concepts, denoted as CGS/CAES, provide for continuous operation of CGS and the reheat turboexpander train which are high temperature components, thus improving their operation and extending life resource. A parametric thermodynamic analysis is performed for several CGS/CAES concepts differentiated by their turbomachinery parameters, CGS arrangements, operating cycles, and hours of daily generation. A qualitative cost estimate is made using a variety of sources including published EPRI reports and extensive in-house cost data. A technical and cost comparison is made to the Integrated Gasification Combined Cycle (IGCC) plant.

The Future

This paper covers the development of Compressed Air Energy Storage (CAES) Systems and the methods used to increase performance and efficiency. It shows the evolution from the original non-recuperated cycle to the current designs, and examines the future possibilities of such cycles as CAES at 2500°F (1370°C), CAES with humidification, CAES integrated with coal gasification, and CAES with chemical recuperation.
