Modelling Underground Coal Gasification—A Review [PDF]

open access: goldEnergies, 2015
The technical feasibility of underground coal gasification (UCG) has been established through many field trials and laboratory-scale experiments over the past decades. However, the UCG is site specific and the commercialization of UCG is being hindered due to the lack of complete information for a specific site of operation. Since conducting UCG trials

Early Ideas in Underground Coal Gasification and Their Evolution [PDF]

open access: goldEnergies, 2009
This article follows the development of early UCG (underground coal gasification) ideas. Historical facts are discussed mainly from the technological perspective and early experiments in UCG are analyzed. Our search for the first successful UCG experiment brings to light a new finding, which was commonly overlooked in previous reviews.
