 is an organic matter derived from dead or living organisms.
Biodiesel is an alternative fuel based on vegetable oils or animal fats, also some recycled cooked items. Car engines convert to burn biodiesel in its pure form, and biodiesel is also mixed with petroleum diesel and used in unmodified engines. This fuel is very safe, biodegradable, reduces air pollutants associated with vehicle emissions like carbon monoxide, hydrocarbons, and particulate matter.
These fuels are a blend of natural gas, ethanol, and methyl tetrahydrofuran (MeTHF), a cosolvent derived from biomass. They are used in flexible fuel vehicles because they are clear, high-octane fuels that can be used alone or mixed with gasoline by merely adding to the tank.
Four Emerging Fuels
- Dimethyl ether
- Renewable hydrocarbon biofuels
These emerging alternative fuels may enhance energy security, reduce emissions, improve vehicle performance, and encourage the U.S. economy.
In addition to these, other alternatives such as ammonia may also be used when needed in small quantities.
