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.

Coal Power

A novel compressed air energy storage (CAES) system has been developed, which is innovatively integrated with a coal-fired power plant based on its feedwater heating system. In the hybrid design, the compression heat of the CAES system is transferred to the feedwater of the coal power plant, and the compressed air before the expanders is heated by the feedwater taken from the coal power plant. Furthermore, the exhaust air of the expanders is employed to warm partial feedwater of the coal power plant. Via the suggested integration, the thermal energy storage equipment for a regular CAES system can be eliminated and the performance of the CAES system can be improved. Based on a 350 MW supercritical coal power plant, the proposed concept was thermodynamically evaluated, and the results indicate that the round-trip efficiency and exergy efficiency of the new CAES system can reach 64.08% and 70.01%, respectively. Besides, a sensitivity analysis was conducted to examine the effects of ambient temperature, air storage pressure, expander inlet temperature, and coal power load on the performance of the CAES system. The above work proves that the novel design is efficient under various conditions, providing important insights into the development of CAES technology.

This paper presents preliminary engineering results for a 50 MW Compressed Air Energy Storage (CAES) plant for the Alabama Electric Cooperative, Inc. (AEC). The CAES plant would improve AEC’s power generation mix in two ways: (a) it would provide needed peaking/intermediate power (otherwise purchased) and (b) it would increase the load factor of economical baseload units. The paper presents the following: a. Comparative trade-off analysis of various conceptual arrangements with underground storage depths ranging between 1000 feet and 4000 feet. (The most economical concept is selected based on the consideration of economics of the overall plant including underground storage). b. Engineering and cost data, performance data, construction schedule and environmental data for the selected CAES plant concept. The results of this preliminary engineering effort prove that a CAES plant is a cost effective addition to AEC’s installed power generation plants.

A number of analyses concluded that in order to be cost effective a compressed air energy storage (CAES) plant should have a recuperator, which recovers the low pressure (LP) expander’s exhaust gas heat for preheating the cold cavern air before it enters the high pressure (HP) combustor(s). The use of a recuperator reduces heat rate, and accordingly fuel consumption, by as much as 20–25%. Therefore all feasibility studies on CAES performed for various utilities included a recuperator, and the first CAES plant to be built in the U.S., the 110 MW CAES plant for the Alabama Electric Cooperative (AEC) will utilize a recuperator with a 75% effectiveness.
