Underground Coal Gasifiion (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 gasifiion of the coal takes place underground instead of in a manufactured gasifiion .
