Reducing Emissions from Coal Plants

Reducing Emissions from Coal Plants There are three ways to reduce the CO 2 emissions from a coal plant: 1. Fuel switching - replacing part or all of the fuel with a lower carbon fuel like biomass or natural gas (fuel switching) 2. Efficiency improvement - increasing the efficiency of the plant so less CO 2 is emitted to produce the same output 3.
