What is Renewable Propane Autogas?

Written on: March 13, 2023

An ultra-low carbon fueling solution for light-, medium- and heavy-duty vehicles

propane vehicles united states According to the U.S. Environmental Protection Agency (EPA), roughly 27 percent of this country’s greenhouse gas emissions come from the transportation sector. That is the highest percentage for any sector.

As we look to combat the harmful effects of climate change, corporations, municipalities, small businesses and individuals are searching for ways to travel our roadways in the most environmentally responsible way possible.

For decades, one of the best tools for reducing vehicle emissions has been propane autogas. Over 60,000 autogas vehicles are on U.S. roads right now, with more than 500 autogas service locations across the lower 48 states. And renewable propane is making these fleets even cleaner!

Commercial benefits of propane autogas

Propane’s per gallon price has historically been lower than gasoline and diesel. Today’s almost entirely domestic production of propane helps to moderate the price. Propane has a lower fuel economy than these other fuels, but the price difference offsets this. So, drivers can typically expect better value overall from propane. Because propane autogas burns so cleanly, autogas engines tend to have lower maintenance costs than gas and diesel engines.

Propane autogas vehicles are a more affordable alternative to electric vehicles, too. Installing the infrastructure to fuel 10 autogas vehicles costs up to $60,000, compared to $480,000 for the fast EV charging stations that 10 electric vehicles need.

Additionally, you don’t sacrifice performance when choosing propane over electricity. While electric shuttles can manage 120 miles on a full charge, a comparable autogas shuttle has technology that can provide a range of over 400 miles on a single fill. Range anxiety is not an issue when using propane.

Finally, it’s worth noting that propane autogas is fuel you control with on-site storage and dispensing. Electric vehicles are dependent on an overburdened and unreliable electric grid to run.

Autogas and the environment

In addition to financial and performance benefits, propane autogas significantly outpaces gas and diesel for emissions and air quality. Consider these facts from studies conducted by the Propane Education & Research Council (PERC):

These emissions reductions are great for the environment and the air our families, neighbors and co-workers breathe.

Renewable Propane Autogas is further lowering carbon intensity.

Autogas vehicles are some of the top beneficiaries of renewable propane gas. Because rPG is made from organic and recycled products in a production process with a low carbon intensity (CI), the fuel’s overall CI is even lower than conventional propane — and vastly lower than gasoline, diesel and U.S. grid-based electricity.

U.S. grid electricity138.6
Conventional Propane80.3
Renewable Propane20.5 – 43.5

And rPG can be used in autogas engines without modifications. If your vehicle fleet has the infrastructure to store, dispense and use propane autogas, you can seamlessly incorporate rPG and other innovative blends.

Renewable propane autogas represents a dynamic addition to a fuel supply that is already almost wholly U.S.-produced. Last year, U.S. producers made 4.6 million gallons of rPG, according to the EPA. We anticipate more than 100 million gallons of rPG will come to the market in the next few years. That will keep a lot of clean-driving fleets on the road!
