Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from either syngas, a mixture of carbon monoxide and hydrogen, or a mixture of carbon dioxide and hydrogen. The syngas could be derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas. Alternatively a mixture of carbon dioxide from the atmosphere and green hydrogen could be used for an almost climate neutral production of synthetic fuels.

Common ways for refining synthetic fuels include the Fischer–Tropsch conversion,[1] methanol to gasoline conversion,[2] or direct coal liquefaction.[3]

As of July 2019, worldwide commercial synthetic fuels production capacity was over 240,000 barrels per day (38,000 m3/d), with numerous new projects in construction or development, such as Carbon Engineering. (Fuel for thought)
