How does UCG compare to other energy sources?
UCG syngas burns more cleanly than coal and is comparable to natural gas. Burning UCG-produced syngas after pre-combustion carbon capture produces about the same or fewer greenhouse gas emissions than a combined-cycle natural gas power plant, the cleanest of all fossil fuel plants. UCG-produced syngas also significantly reduces or eliminates other pollutants including nitrogen (NO) and sulfur oxides (SO), mercury, particulates and coal ash.
