Maps and Data - U.S. Alternative Fueling Stations by Fuel Type

This chart shows the trend of U.S. alternative fueling stations by fuel type from 1992 to 2019. Propane stations were the most numerous until 2011, when they were surpassed by electric vehicle supply equipment (EVSE), or charging units. The growth in EVSE units accelerated starting in 2011, following the 2010 increase of plug-in electric vehicles offered by major automakers. 2016 experienced the largest growth for EVSE to support the growing electric vehicle population, followed closely by 2017 and 2018. The number of EVSE units is expected to increase as the population of electric vehicles continues to grow. The number of E85 stations has been increasing steadily since 2004, as the number of flex-fuel vehicles available from major manufacturers has increased. The number of CNG stations decreased between 1996 and 2006 (despite the increase in CNG sales during this time) largely because the average station size was increasing.
