Lignite, or brown coal, is the lowest rank of coal. It has a 46–60 percent fixed-carbon content, but the lowest heating value, 5,500–8,300 Btu/lb (5.8–8.8 million joules/lb) of all coals. Because of its low energy density, lignite coal is inefficient to transport and is not traded extensively on the world market compared with higher coal grades. It is often burned in power stations constructed very close to mines, so-called mine mouth power plants. Emissions from lignite coal fired plants are generally higher than for higher rank coal plants.
About 79 percent of lignite coal is used to generate electricity, 13.5 percent is used to generate synthetic natural gas, and 7.5 percent is used to produce fertilizer products (anhydrous ammonia & ammonium sulfate). A very small percentage is used as home heating fuel, for use as fertilizer and for use as oil well drilling mud.
