Deployment of Underground Coal Gasification in India [PDF]
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.

An Overview of the Chinese UCG Program
Coal is the dominant source of energy in China, but about 50% of the coal resource is left underground unmined. Because of this, the "long-tunnel, large section, two-stage" Underground Coal Gasification (UCG) technology has been put forward, and the UCG ...

Commercial‐scale “green” hydrogen projects use renewable electricity to drive electrolysis—the process of splitting water into hydrogen and oxygen. Producing green hydrogen requires water not only for the electrolysis reaction but also for cooling the electrolyzers, which release waste heat.
