Therefore, people will probably return to coal mining that is never a good idea. 2. Coal gasification is significantly unproven and untested. Since IGCC plants are more costly than conventional coal fired plants, gasification will heavily rely on subsidies. 3. With coal gasification, there is more amount of carbon dioxide produced that will eventually lead to …

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured …

Underground coal gasification (UCG) is a gasification process used to produce gas from coal in situ by injecting air or oxygen into non-mined coal seams and extracting the product gas via surface wells. The resulting synthetic gas ("syngas") can be used to produce electricity, as well as chemicals, liquid fuels, hydrogen and synthetic natural gas.
