The world’s longest biofuels corridor stretches over 1,786 miles through the relatively flat terrain of the north to the rolling hills of the south. It currently includes 26 stations that dispense E85—a fuel blend of 85 percent ethanol and 15 percent gasoline—and 9 stations that dispense E20.

And it is located right here in the United States, stretching from Sault Ste. Marie in northern Michigan to Miami, Florida.

The biofuels corridor was built as part of the I-75 Green Corridor Project, a six-state initiative that has pledged to create a network of biofuel stations along the interstate so that America’s drivers can traverse the entire route running on either E85 or E20.

The I-75 Green Corridor Project began in 2009 with funding through the U.S. Department of Energy Clean Cities Program. The East Tennessee Clean Fuels Coalition, Michigan Clean Energy Coalition, Clean Fuels Ohio, Kentucky Clean Fuels Coalition, Clean Cities Georgia, Central Florida Clean Cities Coalition, Clean Cities Tampa Bay, and Middle Georgia Clean Cities worked to advance the project.

This summer, the I-75 Green Corridor Project is celebrating its five-year anniversary. Pictured above is the current station map for the project. Stations providing E85 are marked in yellow. B20 is marked in blue. Stations that provide both fuels show both colors. Stations that plan to open soon are white. Credit: NAFTC.

Since its inception, the I-75 Green Corridor Project has been enormously successful.

Collectively, the project has sold over 3.3 million gallons of biofuels to customers along the interstate, effectively displacing 2.6 million gallons of petroleum. That means that the U.S. has produced over 61,000 barrels of renewable, American fuel as a result of the project, effectively avoiding 25,222 tons of carbon dioxide. This also equates to eliminating the annual carbon dioxide emissions from 4,817 U.S. passenger vehicles, or the energy used by 2,109 homes for one year.
