I-75 Project Brings Biofuels to One of the Nation’s Longest Highways

With the launch of the I-75 Clean Fuels Corridor, drivers in Tennessee, Kentucky, Indiana, Michigan, Georgia, and Florida can fill up their vehicles at stations in the world’s longest biofuels corridor. Supported by a 2009 award from the Energy Department’s Clean Cities program, the nearly 1,800-mile route includes 26 retail stations selling E85 (an ethanol blend up to 85% that can be used in flexible-fuel vehicles) and 9 stations selling B20 (a 20% biodiesel blend that can be used in diesel vehicles).

The accomplishment addresses a major challenge facing alternative fuel vehicle deployment: having a sufficient number of fueling stations on America’s most popular highways. The I-75 corridor project added refueling locations for E85 and B20 from Sault Ste. Marie, Michigan, to Miami, Florida, allowing drivers to travel along the entire corridor entirely on biofuels. In addition, all of the biofuel pumps are no more than three miles away from an exit on I-75.

As there are nearly 100 models of flexible-fuel vehicles (FFVs) on the market and 10 million FFVs already on the road, many drivers can already use E85. Similarly, there are an increasing number of diesel vehicles for which manufacturers have approved the use of B20, including the newest Ford F-series trucks and Chevrolet Cruze Clean Turbo Diesel. While the vehicles that can be fueled with E85 and B20 can also run on gasoline and diesel respectively, having quick and easy access to biofuels pumps encourages drivers to use them more often.
