WEBIn most power plants, you need to spin a turbine to generate electricity. Coal, natural gas, oil and nuclear energy use their fuel to turn water into steam and use that steam to turn the turbine. Nuclear plants are different because they do not burn anything to create steam. Instead, they split uranium atoms in a process called fission.

WEBIn industrial chemistry, coal gasifiion is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
