DuPont develops world’s first advanced biofuel
“Biobutanol has about 85 percent of the energy content of gasoline,” says Anton. Existing automobiles can run on it without modification, and when it is blended with gasoline, as ethanol is today in many regions of the globe, it will reduce greenhouse gas emissions and petroleum use. “You’ll see basically no difference between gasoline and biobutanol,” Anton says.
Biobutanol will make its debut this fall in the United Kingdom. It is the brainchild of a partnership between DuPont, the second-largest chemical company in the United States, and energy company BP, which will distribute and market biobutanol mixed with gasoline. In addition to its higher energy content, biobutanol can be distributed through existing pipelines, while ethanol cannot. It also can be produced from a variety of plant crops -- wheat, corn, sugar cane and others.
Biobutanol’s initial impact on climate change is not yet certain because that will depend on the mix of gasoline and biobutanol BP uses in the fuel. Anton believes the resulting fuel is likely to be around 16 percent biobutanol and 84 percent gasoline initially.
