Dupont and BP have developed a new generation of biofuel known as biobutanol, which will be introduced in Great Britain next year. (Entry into the U.S. market is currently unknown.)

It is possible to use biobutanol within the existing gasoline supply and distribution channels. The product has the potential to be blended with gasoline at higher concentrations than existing biofuels without needing to retrofit vehicles, and it offers better fuel economy than current gasoline-ethanol blends.

The biobutanol can be produced from a range of feedstuffs, such as sugar cane, sugar beets, corn and wheat. And, in the future, cellulose feedstuffs like grasses, or ag byproducts like straw and corn stalks could be used.
