The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements. Using brown coal for power generation is problematic because of the high water content. It crumbles easily on exposure to the air which reduces its value as a fuel and requires specialised storage.

Coal is a fossil fuel and has been generating electricity in Great Britain since the industrial revolution. But the decarbonisation of the grid will see it phased out by the end of 2024. In 1882, Thomas Edison's Holborn Viaduct coal plant started generating electricity for public use. It was the first power station of its kind, burning enough coal to provide energy to light 1,000 lamps in ...

Electricity generation is universally recognized as the process of generating electric power from sources of primary energy. In 1831 British physicist and chemist Michael Faraday, who is widely acknowledged as the 'father of electricity', was the first to discover electromagnetic induction, that the movement of a wire through a stationary magnetic field could induce an electrical current ...

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

It stands to reason that the less coal used per unit of electricity generated, the less CO2 is produced. One way to support the reduction of the amount of CO2 produced during this process is to improve the efficiency of the steam and gas turbines currently used in the generation process. These turbines convert the heat released (from burning ...
