Underground Coal Gasification | Frack Off

Underground Coal Gasification (UCG) is a process for exploiting coal that cannot be mined because the seams are too deep, thin or fractured. The process involves using the same sort of drilling technology usually used for fracking to get air/oxygen into the coal seam and then set the seam on fire.

Underground Coal Gasification (UCG) - Ground Truth Trekking

Underground Coal Gasification (UCG) involves igniting coal in the ground, then collecting and using the gases that result from its partial combustion. Although the idea dates back over a century, very few UCG plants have ever been built. Underground gasification could potentially allow the use of coal that is currently uneconomical to mine.

Underground coal gasification - SourceWatch

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.
