Most coal is used as fuel. 27.6% of world energy was supplied by coal in 2017 and Asia used almost three-quarters of it. [79] Other large-scale applications also exist. The energy density of coal is roughly 24 megajoules per kilogram [ 80 ] (approximately 6.7 kilowatt-hours per kg).
The coal industry uses the term "clean coal" to describe technologies designed to enhance both the efficiency and the environmental acceptability of coal extraction, preparation and use, [43] but has provided no specific quantitative limits on any emissions, particularly carbon dioxide.
Integrated gasification combined cycle (IGCC) is a coal-based power generation technology that uses a high-pressure gasifier to convert coal (or other carbon-based fuels) into pressurized synthesis gas (syngas). The gasification process allows the use of a combined cycle generator, typically achieving higher efficiency. IGCC also facilitates ...

With the development of the steam engine in the United Kingdom in 1769, coal came into more common use, the combustion of which releases chemical energy that can be used to turn water into steam. [5] Coal was later used to drive ships and locomotives. By the 19th century, gas extracted from coal was being used for street lighting in London. In ...
