Chapter 4. Underground Coal Gasification (UCG) with Carbon Capture and Storage (CCS)
2010Underground Coal Gasification (UCG), taken on its own, offers the prospect of increasing the world's usable coal reserves by a factor of at least three,1 and doing so in a cost-effective manner with the added benefit of avoiding the risk to life and limb that accompanies deep coal mining.

Abstract India is blessed with large reserves of deep seated coal which cannot exploit economically with the available technology. The gap in demand and supply of energy is on rise for the nation. Underground coal gasification (UCG) is a way of accessing the un-mineable coal for its energy contents and as a chemical feed stock.

Abstract Underground gas gasification (UCG) is a clean coal technology which involves in-situ gasification of deep-seated underground coal. The process can be divided in two phases based on state of coal seam and direction of cavity growth. In phase-I, cavity grows mainly in vertical direction while in phase-II it grows in horizontal direction.

Abstract The unconventional use of coal to supplement Natural Gas (NG) in the power and chemical industry makes Underground Coal Gasification (UCG) an important technology in economically producing unconventional gas. Present day exploration and production technologies pave the way "from a potential to actual production ...

Abstract During underground coal gasification (UCG), whereby coal is converted to syngas in situ, a panel (cavity) is formed in the coal seam. Unlike other underground mining methods, the coal and country rocks in the vicinity of a UCG panel are subjected to high temperatures which may be in excess of 1000 °C.

The technology of underground coal gasification to produce synthesis gas requires a flare to dispose of vented surplus gas. Since any coal seam will contain chlorine, there is the potential to produce dioxins (PCDD/F) in the flare flame, provided that chlorinated products are released during the gasification reactions. Because of the sulphur present in
