[1] Introduction/Motivation The total United States carbon dioxide (CO2) emissions for 2014 were 5,404 million metric tons (Mt). Of this, the electricity sector was responsible for 2,043 Mt (37.8%). Coal fired power plants produced 76% of the electricity sector’s CO2 emissions, with the most of the remaining emissions coming from natural gas-fired power plants. With new clean air standards being signed into law every year, coal-fired power plants are facing a serious push towards clean coal technology. Coal resources are abundant throughout the world, inexpensive, and relatively stable in price compared other energy resources such as natural gas. For this reason, coal is expected continue to play a large role as one of the primary energy sources for the generation of electricity in the United States well in 2040 (EIA, 2012). However, the most critical issue with promoting the utilization of coal is to decrease its environmental load. Today, the generation of electricity via coal is extremely dirty; combustion of coal generates larger amounts of sulfur oxides (SOx), nitrogen oxides (NOx), and particulates compared to oil and natural gas. To make it possible to utilize coal in a manner harmonious with the environment, as required by carbon pollution standards in the United States, and contribute to the energy security of our nation, it is important to develop and expand the use of clean coal technology.
