Great pressure results in the creation of bituminous, or "soft" coal. This is the type. most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or sub-bituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachia.
Coal due to its relatively large quantities and wide distribution worldwide has generated renewed interest in research and development with the aim of establishing coal conversion technologies that are technically reliable, environmentally and economically feasible.

Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the ...
Automobiles, for example, are only about 20% efficient in converting the energy stored in gasoline to mechanical work; the rest of the energy is released as heat, either emitted in the exhaust or produced by friction in bearings and tires. The production of electricity by coal- or oil-powered steam turbines (Figure (PageIndex{1})) is can be ...

States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...

Generation of electricity in a nuclear reactor is similar to a coal-fired steam station. The difference is the source of heat. Fissioning, or splitting, of uranium atoms produces energy in the same way burning coal, gas, or oil is used as a source of heat in fossil fuel power plants. The fuel used in nuclear generation is 235 U. The process of ...
Energy conversion technology is concerned with the transformations of energy from forms provided by nature to convenient or useful forms of energy. Harnessing the energy through these sources using efficient technologies is expected to play an important role in serving as clean energy source for mankind. This course covers fundamentals of such ...

Energy is the capacity of something to do work: If something contains a store of energy it is able to do work. If something does not store energy then it will not work. The law of conservation of energy states that: Energy cannot be created or destroyed, it can only change from one form to another. What this means is that the total amount of ...
A calorie (or thermochemical calorie) is a unit of energy in the International System of Units (SI). The symbol for calorie is cal. A calorie is measured as the quantity of heat required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature at a pressure of 1 atmosphere. A calorie is also called a small calorie or gram calorie.

Gasification is a process in which a solid fuel, like coal, is reacted at high temperatures (593–1260°C [1100–2300°F]), generally in the presence of limited O2 and/or steam. The primary gaseous products are H2 and carbon monoxide (CO), with water (H2O) and carbon dioxide (CO2) as substantial byproducts.
