Coal gasification is said to have greater efficiency than conventional coal-burning because it can effectively use the gases twice: the coal gases are first cleansed of impurities and fired in a turbine to generate electricity. Then, the exhaust heat from the gas turbine can be captured and used to generate steam for a steam turbine-generator.

Gasification enables coal-, biomass-, MSW-, and waste plastics-to-liquids by producing syngas followed by Fischer-Tropsch synthesis to generate liquid hydrocarbon-based transportation fuels. Syngas-based fuel synthesis technologies are commercialized at large-scale, but improvements are needed for these technologies to be viable for smaller scales that could be employed in remote areas or near ...

Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...

There is also no experience of underground coal gasification (UCG) combined with carbon capture storage/utilization (CCS/U) or coal-bed methane (Sarhosis et al., 2016b). It is recognized that future commercial projects would require time to demonstrate to investors, regulators, and general public that economic, environmental, and financial risks from the technology can be managed.

But while the vast majority of it is burned at conventional coal-fired power plants, coal is also turned into a gas for conversion into electricity, hydrogen, and other energy products. The U.S. Department of Energy explains that coal gasification is a thermo-chemical process in which the gasifier's heat and pressure break down coal into its chemical constituents.
