<div><font color="#000000">Coal as an energy source has the advantages
of broad availability with large reserves in several countries over
the world, safe and secure supply, low cost, and economic utilization
by mature technologies. The disadvantages are due mainly to
combustion-generated pollution. The pollutants of concern are oxides
of sulfur, nitrogen, and carbon, and fine organic and inorganic
particulates. Remedial technologies fall into the broad
categories of combustion process modifications, post combustion
clean-up, and improvement of the cycle efficiency of power
generation. Merits, limitations and prospects of clean and
efficient power cycles are discussed.</font></div>
<div><font color="#000000"><br></font></div>
<div><font color="#000000">The distant (2020) goal is the development
and application of coal gasification with combined cycle co-production
of electricity and hydrogen, at higher than 60% cycle efficiency, and
with CO2 capture and sequestration. It is expected, however, that more
than 12 GW coal based power generation will be installed before such a
system may become commercial and ready for implementation. In the
intervening period supercritical steam pulverized coal plants, if
chosen instead of conventional, subcritical pressure steam plants,
could reduce pollutant emissions by about 14%, and avoid more than 100
million tons of CO2 emissions during their lifetime. Because of the
marginally higher first costs, incentives are necessary for
investments in clean and high efficiency coal burning electric power
plants to be built in the near future.</font></div>
