According to the US Department of Energy, biodiesel fueling stations are located in every state except Minnesota. Availability varies widely by state. North Carolina has 139 stations and Washington has 51 stations ((the majority of the stations in these two states are for government use only and not available to the public). Eight states have between 21 and 50 stations, 10 states have between 11 and 20 stations, and 29 states and the District of Columbia have 10 or less stations. An interactive map providing the location of all biodiesel fueling station locations in the United States has been prepared by the US Department of Energy and is available here.
