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.

Coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2 ), carbon dioxide (CO 2 ), methane (CH 4 ), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
