In-situ hydrogenation of an underground coal formation is carried out by fracturing the formation and sealing it, to provide an in-situ reactor site. Then a liquid solvent stream and a gaseous hydrogen stream are introduced into the fractured formation, allowing reaction and conversion of the coal to lighter, hydrogenated components.
