Climate implications of underground coal gasification

This study, commissioned by the European Climate Foundation, reviews the technical and economic status of Underground Coal Gasification (UCG) technologies, and develops a series of scenarios to assess the possible implications for the climate. It finds that the technical and cost obstacles to effective deployment of high levels of carbon capture in UCG are more significant than advocates of the technology acknowledge, and that the risk of increased or prolonged unabated use of coal as a result of UCG could become a serious climate threat.
