Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989. Although it previously used a hydrous ethanol blend, Brazil shifted toward the aforementioned anhydrous ethanol, which is used in a ratio of ethanol to gasoline of 20-24:80-76. Named flex-fuel vehicles (FFVs), these automobiles run on gasoline, ethanol, or any blend of the two. by Brian J. Donovan, CEO Renergie, Inc.
