SAN FRANCISCO - DuPont and BP, riding the global wave of enthusiasm for bio-based fuels, announced today that the two companies have developed a new biofuel called biobutanol that they say has 30% more energy density than ethanol. "Biobutanol is higher performance in the engine, and that will translate into higher miles to the gallon," said DuPont Chief Executive Charles Holliday.
