Fossil fuels - coal, oil and gas - contain energy that can be converted into other forms through combustion. Coal in solid form is largely made up of the element carbon in pure form, while oil is rich in compounds of carbon and hydrogen - hydrocarbons. In 1913 Friedrich Bergius developed a method for transforming a solid form of coal - lignite - into liquefied oil. The method entails exposing the coal to hydrogen gas under high pressure to form hydrocarbons. The process has been used primarily to produce fuel for vehicles.
