Gas vs Coal

Gas vs Coal The CO2 emissions from Natural Gas Combined Cycle (NGCC) plants are reduced relative to those produced by burning coal given the same power output because of the higher heat content of natural gas the lower carbon intensity of gas relative to coal and the higher overall efficiency of the NGCC plant relative to a coal-fired plant (1)

The four stages in coal formation are peat lignite bituminous and anthracite Each of these stages must be completed for coal to form Stage one in coal production is peat Peat is a fibrous substance that is oxidized by water and carbon dioxide When a plant dies and stays under water it builds up an accumulation of peat

• Without carbon capture open cycle natural gas turbines and combined cycle natural gas turbines cause 2 8 and 2 3 times respectively the global warming per unit energy over a 20-year time frame as a coal plant and only 8-28 percent less warming over 100 years than a coal plant • The reason is the higher SO 2 and NO x and lower CH
