For one month gasoline consumers in Canada will be buying cellulosic ethanol made from agricultural residue at their local gas stations. Iogen, of Ottawa, Ontario, and Royal Dutch Shell, of The Hague, Netherlands, are placing their cellulosic ethanol into commercial gasoline at a Shell plant in Ottawa. Since 2004, the companies have partnered on Iogen's demonstration plant, capable of producing per month 40,000 liters of cellulosic ethanol, and in July 2008 Shell increased its ownership stake in Iogen to 50%. Still, as there is not yet an established market for cellulosic ethanol, the Ottawa-based demonstration facility is churning out a product with no real buyer. To combat this, the companies are including 10% cellulosic ethanol in the gas for a month beginning June 10, and expect to sell a total of 60,000 liters of second-generation biofuel. Similar events may follow, Iogen says. But as cellulosic fuel advances, stockpiled product could plague other makers. Lignol Energy, of Vancouver, British Columbia, announced in June it had completed an end-to-end production of cellulosic ethanol in its biorefinery pilot plant in Burnaby. They might take note of Iogen's solution. Mandy Chepeka, director of communications at Iogen, says selling the fuel shows the public that “we were making this in quantities sufficient enough to be distributed,” and that “we are past the point of being in a test tube or in an R&D lab.”
