Coal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.
