The thermal energy stored in TES is normally absorbed from the working fluid of thermal power plants (, the superheated steam [26], [27] or hot water [28], [29]). However, large irreversibility exists in the heat exchange process between the steam and heat storage media due to the pinch point phenomenon [30].

The water heats up to nearly 400 degrees Fahrenheit (200 degrees Celsius) before returning to the surface. Once there, it transfers its heat to another liquid with a low boiling point, creating steam. The pressure of steam expanding spins a turbine to produce electricity like in a coal or natural gasfired plant.
The thermal electricity supplied by ENGIE in numerous countries is based on a variety of technologies: Traditional thermal power plants: also called combustion power plants, they operate with energy produced by a steam boiler fueled by coal, natural gas, heating oil, as well as by steam activates a turbine which, in turn, drives an alternator to produce electricity.
Thermal energy stored in the lowtemperature TES was used to preheat the feedwater after it leaves the condenser and to produce process steam for other applications in the IGCC plant. This concept study also predicted a 5% to 20% reduction in levelized cost of power compared to other coalfired alternatives.
It is a 3,520,000kilowatt coalfired facility that provides electricity for Georgia. As this diagram shows, the plant operates on the same principles as other fossilfueled electric generating plants—it burns coal to produce heat that turns water into steam, which then turns turbines in a generator.

It stands to reason that the less coal used per unit of electricity generated, the less CO2 is produced. One way to support the reduction of the amount of CO2 produced during this process is to improve the efficiency of the steam and gas turbines currently used in the generation process. These turbines convert the heat released (from burning ...
