Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C.
Lignite: Lignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F). It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United
South Australia government to help fund Australia's first renewable-powered hydrogen electrolyser plant – a 15MW facility to be built at Port Lincoln, along with a 10MW hydrogen-fired gas turbine, fuelled wind and solar, and a 5MW hydrogen fuel cell.
The environmental impact of nuclear power results from the nuclear fuel cycle, operation, and the effects of nuclear accidents.. The greenhouse gas emissions from nuclear fission power are much smaller than those associated with coal, oil and gas, and the routine health risks are much smaller than those associated with coal.
