Deployment of Underground Coal Gasification in India [PDF]

Current Science, 2017
Globally, the sheen of coal-based energy production is slowly wearing, with few exceptions of developing novel technologies that aid in coal gasification and gas clean-up. Underground coal gasification (UCG) is one such tool that can be used for extracting energy contained in otherwise inaccessible reserves.
