Coal vs. Charcoal

By Jaxson

Main Difference

The main difference between Coal and Charcoal is that the Coal is a combustible rock and Charcoal is a fuel.

  • Coal

    Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

    Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.As a fossil fuel burned for heat, coal supplies about a quarter of the world’s primary energy and two-fifths of its electricity. Some iron and steel making and other industrial processes burn coal.

    The extraction and use of coal causes many premature deaths and much illness. Coal damages the environment; including by climate change as it is the largest anthropogenic source of carbon dioxide, 14 Gt in 2016 which is 40% of the total fossil fuel emissions. As part of the worldwide energy transition many countries have stopped using or use less coal.

    The largest consumer and importer of coal is China. China mines account for almost half the world’s coal, followed by India with about a tenth. Australia accounts for about a third of world coal exports followed by Indonesia and Russia.

  • Charcoal

    Charcoal is the lightweight black carbon and ash residue hydrocarbon produced by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis — the heating of wood or other substances in the absence of oxygen. This process is called charcoal burning. The finished charcoal consists largely of carbon.

    The advantage of using charcoal instead of just burning wood is the removal of the water and other components. This allows charcoal to burn to a higher temperature, and give off very little smoke (regular wood gives off a good amount of steam, organic volatiles, and unburnt carbon particles — soot — in its smoke).
