Does UCG have any environmental benefits?
UCG accesses the coal through boreholes and recovers the coal transformed into a gas. It eliminates the surface disturbance associated with large mines, removes people from underground hazards, leaves rock and ash in the coal seam underground, preserves groundwater levels, and produces the energy in an efficient and easily processed form as gas. It is the lowest cost route to all the new clean coal technologies which are based on coal gasification, and provides the most economic method for carbon capture.
