The EPA has indicated that it will decide by late summer on whether to allow higher levels of ethanol to be blended into gasoline. Three issues should be of concern. The first would be the fuel efficiency of ethanol, particularly versus biobutanol. The second would be the economic viability of these biofuels. And the third would be the impact on emissions at this higher level, especially the emission of acetaldehyde.
EPA Approval Later This Summer for Ethanol Inclusion Rates of 15%?
March 4, 2010
The EPA will complete engine testing of higher ethanol inclusion rates by May, 2010 compiling the data to make a decision on potentially higher blend rates (15%) of ethanol into the gasoline. The current maximum allowed blending rates are 10%. Rates of 35% are already used in Brazil where all car manufactures and small engine manufactures sell similar engines as the United States.
