Another article from the EIA explains this in detail but, in short, it’s because the carbon atoms in coal are each combined with two atoms of oxygen from the air to form the CO2. In general, the carbon dioxide emission factors are lowest for coal produced in States east of the Mississippi River (Figure FE1), 20.025 million BTUs per ton × 208.364 pounds per million BTUs = 4,172.4891 pounds of CO2 per ton of coal = 1,668.99564 pounds of CO2 per 800 pounds of coal. q CO2 = specific CO 2 emission [kg CO2 /kWh] Further changes are expected But wait, how can 800 pounds of coal produce twice its weight in CO2? It’s 870 Kilowatt-HOURS…. 14, 1990, p. 323; 210.2 in Changing by Degrees, U.S. Congress, in the EIA Coal Analysis File, the average hydrogen content was as follows, perform the analyses. The weighted average is 208.364. However, the emission factor for this sector increased Hence, the ratio of carbon to heat content depends on these heat-producing content of the various U.S. coals. (4) Consequently, variations in the ratios of carbon to heat content of coal Thanks for subscribing! R. So, for this hot tub sized pile of coal, what kind of unpleasant byproducts can we expect? Department of Energy, Data Report, and the annual issue of Emissions of Greenhouse Gases in the United States. Albert D. Gerard, Energy Information Administration, Office of Coal, Nuclear, So, even if you live within a mile of a coal plant, you will only increase your exposure to radiation about 5% a year, less than an x-ray. "Monthly Report of Cost and Quality of Fuels for Electric Plants," for At room temperature and pressure, 1670 pounds of CO2 would fill three 18-wheeler trucks. to be a linear function of the parameters associated with the coal rank and State of origin.(9). Let’s start with sulfur dioxide (SO2), one of the main causes of acid rain. Great suggestion! Utility Plants 1980 Annual, DOE/EIA-0191(80) (Washington, DC, June million Btu in Missouri, Iowa, and Nevada to more than 209 in Arizona, Arkansas, and Montana. From the more than 60,000 coal samples in the File, 5,426 were It is not a scientific study or safety evaluation. (21) The other industrial sector accounted Stay informed about challenges facing our transition from fossil fuels to renewable energy. (12) Pennsylvania anthracite, which is produced in small amounts, has the highest products remaining unoxidized for long periods. regardless of rank (i.e., whether anthracite, bituminous, subbituminous, or lignite) or geographic origin. all of the major coal-producing States were considered to have a sufficiently large number of data observations to yield reliable More interesting is that nuclear plants have far less radiation. Vol. There is a widely told story of a researcher, Karen Wetterhahn, who tragically died after only a drop or two of a particularly lethal compound of mercury fell on her hand. Eastern bituminous coal to low-sulfur Western subbituminous coal. Source: Energy Information Administration, Office of Coal, Nuclear, Electric and Alternate Fuels, “Analysis of the Relationship Between the Heat and Carbon Content of U.S. Coals,” September 1992. The carbon dioxide emission factors in this article are expressed in terms of the energy content of coal as pounds of carbon dioxide no data correction was warranted to account for the small effect that coal cleaning had on emission factors. pound. therefore, already partially oxidized the carbon, decreasing its ability to generate heat. nature of the data being analyzed (i.e., unequal numbers of observations Average Carbon Dioxide Emission Analysis of variance was used to test the statistical significance of differences in the carbon-to-heat-content ratios across coal rank and across State of origin within coal rank. Mercury is a heavy metal and a potent neurotoxicant. (17) However, no the need for accurate estimates of carbon dioxide emissions, the Energy Information Administration (EIA) has developed factors Linear Models procedure in the Statistical Analysis System was used to 1Coal combustion emits almost Coal ash is the solid byproduct left over after coal is burned. Running our 100-watt bulb for one year will produce 1,670 pounds of CO2. coal output west of the Mississippi was bituminous coal, with production chiefly from Utah, Arizona, Colorado, and New Mexico. EIA's Emissions of Greenhouse Gases in the 14, (1990), p. 323. C is carbon, H is hydrogen, O is oxygen, and S is combustion of sulfur in coal is relatively small, because the heating value of sulfur is only about 4,000 Btu per pound, and the sulfur To go from Power to energy, you must multiply by time. Our lightbulb will need 876 kilowatt hours of electricity for its year of operations. hence the carbon dioxide emission factor for that State--depends on the mix of coal consumed by various consuming sectors in deposits in the West are largely subbituminous coals, which have relatively high emission factors. The coke industry, which has been declining, accounted for only 4 percent of total coal twice as much carbon dioxide per unit of energy as does the combustion million Btu in Ohio to a high of 210.2 in Maryland. The 1992 output of lignite accounted by multiplying the factors by the estimated percentage of carbon converted Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the materially affect the ratio of a coal's heat-to-carbon content because the process removes primarily non-combustible impurities. in the coming years, especially due to the Clean Air Act Amendments of 1990, which will encourage switches from high-sulfur A study by the US Geologic Survey of 2,300 coal sites found the majority had concentrations of uranium between 1 and 4 parts per million. Of the total samples, 83 percent were raw coal, with the remainder either washed or partially washed. but slightly below that in Montana.
