Underground coal gasification (UCG) is an industrial gasification process, which is carried out in nonmined coal seams. It involves injection of a gaseous oxidizing agent, usually oxygen or air, and bringing the resulting product gas to the surface through production wells drilled from the surface.
Coal is the most important energy source in China but the government is becoming increasingly concerned about the pollution caused by burning coal and the environmental damage related to its mining. There is therefore a considerable interest in the development of Underground Coal Gasification
The subject of underground coal gasification came up the other day and I remembered writing about it here: Labour Party Conference 2015 People, meaning to follow it up but other issues crowded it out. At the conference I spoke to delegates from the North East who warned of the imminent threat of .
May 29, 2002· Engineers plan to set fire to a coal seam deep underground in the first in a series of subterranean blazes around Britain that, they claim, will provide clean fossil fuel energy for generations.
Oct 06, 2016· Scotland''s energy minister is to make a statement on the future of underground coal gasification (UCG) in the country. Environmental groups have said they hope Paul Wheelhouse will announce a ban ...
Underground coal gasification (UCG) should not be confused with hydraulic fracturing, also known as fracking, or coalbed methane (CBM) extraction. Hydraulic fracturing and CBM are entirely different technologies that are both covered by a separate moratorium on unconventional oil and gas (UOG).
The UK was the originator of underground coal gasification (UCG) technology almost a century ago, when Sir William Ramsay conducted exploratory experiments beneath Hett Hill in County Durham in 1912. World War I put a stop to these experiments, and UCG was later neglected in the UK while its abundant domestic reserves of oil and gas were exploited.

Apr 27, 2016· Underground coal gasification is an underground coal controlled combustion process, the combustible gas generated by the thermal effect of coal and chemical action.
Dec 08, 2016· Underground coal gasification (UCG), which involves injecting oxygen and steam underground to release gas from coal seams, would massively increase UK carbon emissions if exploited, according to a ...
Oct 06, 2016· Paul Wheelhouse, the Energy Minister, said an independent review commissioned by the Scottish Government concluded that Underground Coal Gasification (UCG) found that a .
Apr 14, 2014· The UK government has established a working party to investigate the merits of UCG, undoubtedly excited by the vast resources of coal sitting under the North Sea. ... Underground Coal Gasification ...
Underground coal gasification: From fundamentals to applications. ... Underground coal gasification (UCG) is a promising option for the future use of unworked coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells. The coal is ignited and air is injected underground to sustain a fire, which is essentially ...
Dec 08, 2016· Review of the greenhouse gas implications associated with underground coal gasification (UCG). Underground coal gasification: evidence statement of global warming potential Skip to main ...
Underground Coal Gasification (UCG) is a process for exploiting coal that cannot be mined because the seams are too deep, thin or fractured. 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.
Oct 08, 2015· The Scottish government has imposed a moratorium on underground coal gasification (UCG). Cluff Natural Resources had been planning to use the technique to .
Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an insitu gasification process, carried out in nonmined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.

The Scottish Government has today put in place a moratorium on underground coal gasification (UCG) in Scotland. This is separate to the existing moratorium on onshore unconventional oil and gas, including hydraulic fracturing – and comes as ministers have also informed Parliament that the Government will carry out a thorough and wideranging research process into the potential impacts of ...
Underground coal gasification (UCG) is a gasification process used to produce gas from coal in situ by injecting air or oxygen into nonmined coal seams and extracting the product gas via surface wells. The resulting synthetic gas ("syngas") can be used to produce electricity, as well as chemicals, liquid fuels, hydrogen and synthetic natural gas.
The paper reviews the most recent underground coal gasification field trial and modelling experience and refers to the pubic concern and caution by regulators that arise when a commercial or pilotscale project seeks approval. It will propose solutions for the next generation of underground coal gasification projects.
