The president of one of the world’s largest ethanol plant engineering and construction firms is pleased with the progress made by the industry in the last 30 years, but frustrated by the barriers to higher ethanol blends. At the recent National Ethanol Conference, where ICM, Inc. founder Dave Vander Griend was honored with the Renewable Fuels Association 2012 Membership Award, he talked about how ethanol could replace some of the additives currently found in gasoline – called aromatics – which are used to help boost octane in gas. “We’re looking just to go from 10% ethanol to 15% ethanol with a clean, non-toxic product,” he explained. “The petroleum industry can go from 10 to 40% aromatic additions to their gasoline anytime they choose.”
He noted that Henry Ford’s Model T engine was originally designed to run on either gasoline or ethanol. “Actually, the first FFV was a Model T,” said Vander Griend. “That wasn’t something that set well with Rockefeller – he wanted everything to be gasoline, but at that time there was no octane additive to put into the gas so it wasn’t very good and cars would ping and knock. Taking that fuel they made then, if they would have added 20-30% ethanol, both parties would have won.” Instead, they got rid of ethanol through prohibition and used lead to increase octane. The creation of the EPA got the lead out of gasoline, which led to MTBE being used as a replacement until that was determined to be carcinogenic.
Vander Griend believes that ethanol could reduce tailpipe emissions by up to 50% with just a 30% blend. “Ethanol can replace aromatics on a 1-to-1 (basis) and actually give them more octane than they had from the aromatics,” he said.
