A major objective of the US energy program is to develop environmentally acceptable ways to use coal. Underground coal gasification (UCG) is one of the most promising of these processes. It offers 3 major advantages as a source of synthetic fuel: (1) pipeline quality gas at costs competitive with or lower than that of other synfuels; (2) use of as much as 1.2 trillion tons of coal (triple the present coal reserves) that would not be economical to strip or deep mine; and (3) possible environmental advantages. This study reviews the state of the art in UCG, with emphasis on the US Department of Energy program. The conclusion is that UCG can recover the energy in unminable coal seams to ease demand for imported oil and natural gas, and a commercial UCG process could be onstream by the late 1980s. 34 references.
