underground coal gasification (ucg)

Underground coal gasification (UCG) is a process where coal deposits are converted into useful gases by reacting them underground, typically in non-mined coal seams. This technique involves injecting oxygen or air into the coal seam, creating a controlled combustion process, which then produces a mixture of gases like methane, hydrogen, carbon monoxide, and other byproducts. These gases can be used to generate electricity, produce fuels, or for other industrial applications.
