The number of retail gas stations that can sell motor fuel that can be up to 85 percent ethanol, known as E85, has more than doubled over the past six years to more than 2,500.
According to the Energy Department’s Alternative Fuels Data Center (AFDC), Minnesota continues to lead the nation, with 336 E85 retail locations. States outside of the Midwest have shown the fastest growth, including California and New York, which have seen some of the fastest growth in new E85 fueling stations, increasing from fewer than a dozen stations combined in 2007 to more than 80 stations each in 2013.
Currently, 2 percent of all retail stations in the US offer E85, serving the approximately 5 percent of the light-duty vehicle fleet capable of running on E85.
Retail stations selling E85 have historically been concentrated in the Midwest, where they benefit from a readily available ethanol fuel supply. In 2007, the earliest year for which state-level data are available, the majority of E85 stations were located in just five states—Minnesota, Illinois, Indiana, Iowa, and Wisconsin. However, the pace of the increase has slowed.
