Mar 29, 2010· Underground coal gasification has been pursued for nearly a century and today there are nearly 20 such projects in various stages of planning and development. Eskom, a South African utility company, is planning to build a gigawatt combined cycle plant to be run entirely on syngas from underground gasification.
WhatsAppUnderground Coal Gasification – The Warrior's Call
Underground Coal Gasification The process involves using the same sort of drilling technology usually used for fracking to get air/oxygen into the coal seam and then set the seam on fire. By controlling the amount of oxygen injected it is then possible to only partially burn the coal and bring the gases produced to the surface where they can be burn to produce energy.

With advances in methods for directional drilling...
UNDERGROUND COAL GASIFICATION (UCG)
Most of these projects were abandoned in the 1960s due to falling energy prices. Linc energy recently has conducted a four year test project in Australia called Chinchilla which gasified 35,000 tons of coal. Germany is also planning a test project in Aachen that would combine UCG with carbon capture.
Underground gasification of coal and lignite | SpringerLink
The underground gasification of coal and lignite is of interest when traditional coal extraction is impossible or unprofitable and also with increasing demand for thermal and/or electric power. In the Soviet Union, at six industrial Podzemgaz stations, beginning in the 1930s, more than 15 million t of coal was processed to obtain more than 50 billion m 3 of gas.
Underground Coal Gasification | Interviews | Naked Scientists
Jun 19, 2011· There you would gasify coal to turn it into a mixture of hydrogen and carbon monoxide and that's what we brought into your homes. With underground coal gasification the difference is that you don't have to mine the coal before you gasify it. So you're injecting oxygen and steam into the coal while it's still in the coal seam.
Coal Based Energy in Botswana: CoaltoLiquids, CoalBed ...
An underground gasification operation usually involves the drilling of two wells into an underground coal deposit. One is the injection well where air, oxygen, and or steam are injected into the burning coal bed and the other is the production well where the produced syngas is drawn out from underground.

Jun 15, 2014· Underground coal gasification (UCG) is a promising technology to reduce the cost of producing syngas from coal. Coal is gasified in place, which may make it safer, cleaner and less expensive than using a surface gasifier. UCG provides an efficient approach to mitigate the tension between supplying energy and ensuring sustainable development.
