Portland International Airport Boasts One Of The Largest Installations of Electric Vehicle Charging Stations at an Airport in the US: including some 42 PowerPost® EV Chargers

Portland International Airport Boasts One Of The Largest Installations of Electric Vehicle Charging Stations at an Airport in the US: including some 42 PowerPost® EV Chargers

Counting electric vehicle charging points of late seems to destroy the US government's alternative fueling station counter.

In the latest U.S. DOE Office of Energy Efficiency & Renewable Energy report, charging points were summarized with the other types of alternative fuel stations available today, and it turns out that public EVSEs have quickly exceeded all the other types combined.

Totals have jumped from around 3,500 in 2011, to ~30,000 in 2015.

The problem with such a basic comparison is always that there are different categories of charging points - from individual low power and very slow L1 AC charging, to much faster 50-120 kW DC fast chargers, which more likely reminds consumers of the conventional refueling process.

Anyway, even if we would isolate DC fast chargers, we would see growth, and good sign that one of the alternative fueling technologies have finally taken hold.

"In 2015, there were about 3,600 propane stations, 3,000 E85 stations, and 1,600 compressed natural gas (CNG) refueling stations. The other fuel types (biodiesel, liquefied natural gas (LNG) and hydrogen) altogether have less than 1,000 stations nationwide."

A separate problem to the tally is the different plug standards of DC fast chargers, which effectively reduces the number of charge points in the tally (because you can't switch between standards depending on the hardware you find in place upon recharging).

As a bonus we found a strange data point presented by the DOE on hydrogen fuel stations; believe it or not, there were only 39 stations reported in service for 2015 - which is down from 63 in 2009. 2015 was also the fourth consecutive year of decrease.

Notes:

Starting in 2011, electric charge equipment was counted by the plug rather than by the geographical location. This is different than other fuels, which only count the geographical location regardless of how many dispensers or nozzles are on site.Stations selling low-level biodiesel blends (less than B20) are included in the station listing only for the years 2005-2007.Total is the total number of fuel types sold at stations. Stations are counted once for each type of fuel sold.Acronyms: n/a: Data not available CNG: Compressed natural gas E85: 85% ethanol, 15% gasoline LNG: Liquefied natural gas
