Coal-fired power plants,while providing over 40% of the world’s electricity, are responsible for more than 70% of the CO2 arising from electricity generation.
-
Increasing the current average global efficiency of coal-fired power plants from 33% to 40% through advanced technology could cut upto 2 gigatons of CO2 emissions, which is about 40% of total US CO2 emissions in 2017.
-
Integrated Gasification Combined Cycle (IGCC),Coal gasification,Ultra Supercritical combustion and Circulating fluidized bed (CFB) combustion are few of the advanced technologies to improve efficiency and reduce emissions from Coal power plants.
