Biodiesel (mono alkyl esters) is a cleaner-burning diesel fuel made from natural, renewable sources such as vegetable oils. Just like petroleum diesel, biodiesel operates in combustion-ignition engines. This means that no engine modifications are required, and biodiesel maintains the capacity and range of diesel. The use of biodiesel in a conventional diesel engine results in a large reduction of unburned hydrocarbons, carbon monoxide, and other matter harmful to the environment.

Biodiesel research and development projects are ongoing under the Department of Energy in the Alternative Fuels Utilization Program and under the Department of Agriculture in the Alternative Agricultural Research and Commercialization Center and the Agricultural Research Service. Additionally, the USDA, the Department of Defense, and the DOE provide some special grant money to biofuels research projects, several of them for biodiesel.
