Underground Coal Gasification (UCG) -

History of UCG. Underground coal gasification is a technology that has been discussed and experimented with for over 150 years. It was used at several sites in the former USSR, including a facility in present-day Uzbekistan that has been in operation since 1961. Interest in UCG was high after World War II, and a number of pilot projects were started across Europe.
