About this deal

Fossil fuel consumption has increased significantly over the past half-century, around eight-fold since 1950, and roughly doubling since 1980. Gençsü, Ipek (June 2019). "G20 coal subsidies" (PDF).

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. [2] Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. [3] [4] Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. [ citation needed] In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. [5] Some iron and steel-making and other industrial processes burn coal. China is the largest producer of coal in the world. It is the world's largest energy consumer, and coal in China supplies 60% of its primary energy. However two fifths of China's coal power stations are estimated to be loss-making.

A top priority of the UK COP26 Presidency is to accelerate the global transition from coal to clean energy. The UK government is asking governments to set coal phase out dates and end overseas coal investments, and has set up the Energy Transition Council to bring together partners to ensure that clean power is the most attractive option for developing countries and to support just transitions.

Coal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization. [83] Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using CCS would emit slightly less than the oil process but at a high cost. [84] State owned China Energy Investment runs a coal liquefaction plant and plans to build 2 more. [85] If the refiner wants to produce gasoline, the syngas is routed into a Fischer–Tropsch reaction. This is known as indirect coal liquefaction. If hydrogen is the desired end-product, however, the syngas is fed into the water gas shift reaction, where more hydrogen is liberated:
