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.
Gasification of biomass is a thermochemical process in which solid biomass is treated with a limited amount of gasifying medium to convert it into valuable gases such as Methane (CH 4), Carbon Dioxide (CO 2), Carbon Monoxide (CO), and Hydrogen (H 2) and a solid residue named gases can be further converted to liquid fuels via the FT process or heat and energy for power generation ...

Rs 20,000 crore will be invested in coal gasification projects by 2030 for ecofriendly utilisation of the fuel, which is abundantly available in the country. With this technology, coal can be gasified to turn it into a clean syngas or synthesis ...
This novel approach to the steam gasification of carbon holds promise for the production of high purity H2 from coal or biomassbased electrochemical processes at much lower operation ...
Coal Gasification Process. During gasification, oxygen and steam (water vapour) are blown through the coal while it is still being heated (and in a few cases pressurised as well). "Allothermal" refers to a procedure in which the coal is heated by external heat sources, whereas "autothermal" refers to a process in which the coal is ...

The process involves pumping oxygen and steam through a small borehole into the coal seam to produce a small and controlled combustion. Unlike coalbed methane, therefore, the actual coal is converted from a solid state into gas. The hydrogen, methane, carbon monoxide and CO2 are then siphoned off through a second borehole.
