Dr. James (Jim) R. Macias, manager of the U.S. Fuels Technology Group for Shell Global Solutions, talks about Cellulose Ethanol and BioFuel. The benefit’s of these alternative energy sources make them rather appealing. Cellulosic Ethanol and BioFuel are both made from renewable resources; Cellulosic ethanol is made from corn, sugar, and starches, while BioFuel, mainly BioDiesel, is usually made from Seed oils. Not only are they easily produced (and reproduced), but they also minimalize the CO2 footprint that most combustion engines have. To do this, Shell has teamed up with Iogen, a manufacturer of Cellulosic Ethanol.
