Because of countermeasures against air pollution in big cities, diversification of fuels, and CO2 reduction for global warming, commonplace non-petroleum automotive fuels are expected. Gas to liquid (GTL) and Dimethyl ether (DME) are good for energy security, DME is good for countermeasure against air pollution in big cities with its soot-free combustion. Biofuels, such as Bioethanol and Biodiesel, are good for CO2 emission reduction with their‘carbon-neutral’characteristic. Investigation of a variety of new fuels has been actively conducted for those purposes. In this report, R&D trends of GTL, biodiesel fuel, and DME are introduced as typical non-petroleum automotive fuels.
