Is coal gasification the clean energy of the future?

A very different way to produce gas from coal is known as underground coal gasification (UCG), a process that has been around since the 19th Century but which has yet to become commercially viable on a grand scale – there is currently one working facility in Uzbekistan and pilot projects in Australia and South Africa. According to Julie Lauder, chief executive of the UCG Association, the

ground, where mining of coal by other techniques is not economically favorable. For such in situ gasification, low-Btu gas may be a desired product. Low-Btu gas contains 5 principal components with around 50% v/v nitrogen, some quantities of hydrogen and carbon monoxide (combustible), carbon dioxide, and some traces of methane. The presence of

Auction for commercial coal mining begins with investor

Hoping to attract a slew of investors for India's first auction of coal mines for commercial mining and sale process, the Ministry of Coal has liberalised the terms of qualification. However, the final decision on successful bidders will need government approval. There is effectively no strict eligibility criterion for participating in the auction. The companies/joint ventures should be

v118n10a1 SAUCGA: The potential, role, and development of

Underground coal gasification (UCG) is a process used to produce synthesis gas from coal in situ, that is, in the coal seam. UCG is an emerging, advanced clean coal technology that offers a potential solution for these challenges, as it can cost-effectively and cleanly liberate vast coal resources in the country that currently cannot be economically exploited using traditional mining

Coal gasification : definition of Coal gasification and

Coal gasification is the process of producing coal gas, a type of syngas–a mixture of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2) and water vapour (H 2 O)–from coal.Coal gas, which is a combustible gas, was traditionally used as a source of energy for municipal lighting and heat before the advent of industrial-scale production of natural gas, while the hydrogen obtained

Underground coal gasification is a process which enables

Underground Coal Gasification (UCG) is a gasification process applied to non-mined coal seams, using injection and production wells drilled from the surface, which enables the coal to be converted in situ into product gas. The process has produced commercial quantities of gas for both chemical processes and power generation. The UCG process developed, refined and practiced by Ergo Exergy is

Two IGCC electricity generation plants are in operation in the U.S.

Coal Gasification

Though coal gasification is often touted as a "clean coal" process for this reason, it is by no means clean.
