As the number of vehicles that operate on propane autogas increases, a “new” yet similar fuel that reaches near-zero-emissions is coming into play. That fuel is renewable propane. Many experts predict the entire worldwide demand can be met with renewable propane in 20 years.
Why Renewable Propane?
Renewable propane is a non-fossil fuel produced from 100% renewable raw materials, such as beef fats, vegetable oils, grease residue, and other biomass feedstocks that are inexpensive and abundant. Sometimes referred to as “biopropane,” renewable propane has the same benefits as conventional propane autogas, which has been used for over a century as a transportation fuel and to fuel our home heaters and backyard grills.

Both propane types reduce emissions, cut costs, and provide fleets with the same vehicle performance and reliability. Simply put, the chemical structure and physical properties of renewable and conventional propane are the same — they just come from different sources.

How Does it Work?
Propane autogas vehicles don’t need to be retrofit to accept renewable propane. Renewable propane can be used as a “drop-in” replacement fuel because it’s chemically nearly identical to conventional propane. Since it’s produced from raw and renewable materials, renewable propane has an even lower carbon intensity than conventional propane and is far cleaner than other energy sources. At the point of combustion, renewable propane is carbon neutral.
“Renewable propane’s benefits are amplified when coupled with ultra-low NOx engines that are 90% cleaner than the EPA’s most stringent standard,” said Joy Alafia, president of Western Propane Gas Association.

What’s the Demand?
Pricing is competitive with conventional propane. As the demand grows in places like California, the producers of renewable propane will develop the infrastructure to distribute this fuel efficiently.

Already on the West Coast, U-Haul purchased its first million gallons of renewable propane, available to customers at U-Haul autogas facilities across Southern California.
According to the Western Propane Gas Association, this initial U-Haul purchase and customer offering of renewable propane have the effect of eliminating 5-million tons of greenhouse gas emissions from the atmosphere. And the association said renewable propane is on track to play a major role in California’s green energy future, with the industry targeting 2030 for supplying the state with a 100% sustainable energy source.
Many companies worldwide are developing renewable propane production technology, with some in commercial volume as a byproduct of renewable diesel plants.
Renewable propane is produced in several European and Asian countries. Several U.S. refineries in California, Texas, and Louisiana have the existing capacity to produce renewable propane as part of their renewable diesel production systems.
Research is being done on the merits of renewable propane by the Propane Education & Research Council (PERC), a nonprofit that provides leading propane safety and training programs. The council is testing renewable propane, including blends with conventional propane and standard development. It has been informing OEMs of potential engine use and creating awareness of the fuel for the producer, seller, transporter, and end-user.
