The company, formerly known as Joule Biotechnologies, claimed in 2009 that its organisms could in theory produce as much as 20,000 gallons of ethanol on an acre of land in single year. Company officials now say their target is 25,000 gallons per acre, and that efficiencies they have already demonstrated take them 60 percent of the way to that goal.
The achievement would put Joule's fuel ahead of cellulosic ethanol in terms of productivity. "Even at 60 percent of our ultimate goal, our productivity is still leaps and bounds above cellulosic ethanol," says Dan Robertson, Joule Unlimited's senior vice president of biological sciences. Cellulosic fuels such as grass and wood chips yield only 2,000 to 3,000 gallons of ethanol per acre per year, Robertson says.
