Propane is the most widely used clean fuel globally, with more than 25 million vehicles operating worldwide. It makes a significant contribution to improved environmental outcomes in transportation, in both greenhouse abatement and reduced pollution levels.
St. Francis School District: A Case for Propane as a Transportation Fuel
Independent School District 15, headquartered in St. Francis, Minnesota, deployed 41 propane school buses in their 51-bus fleet. They’re saving $200,000 per year in operating costs, reducing their maintenance costs, and providing a better and cleaner experience for their drivers and students. Watch the video to learn more.
Benefits of Propane
Improve your bottom line. A gallon of propane generally costs 40 percent less than a gallon of gasoline or diesel. Switching to propane can save fleets thousands of dollars annually over traditional gasoline or diesel fleets. In addition, switching to propane means no SCR or diesel particulate filters, lower maintenance costs, and less downtime.
Breathe easier. Compared to gasoline and diesel engines, propane produces less harmful greenhouse gas emissions. Propane shrinks your environmental footprint with 70 percent fewer smog-producing hydrocarbons, 50 percent less carbon monoxide, 20 percent less nitrogen oxide, and 12 percent less carbon dioxide.
Propane has the longest driving range of any alternative fuel option. Due to higher octane ratings and efficient combustion, propane exhibits outstanding performance.
- Horsepower and torque of propane is greater than or equal to its gasoline equivalent.
- Propane enhances performance by providing a 104 octane rating, compared to regular gasoline’s rating of 87.
Propane’s low working pressure, narrow flammability range, higher ignition temperature and rigorous testing make it a very safe alternative fuel.
- Propane has a narrow flammability range.
- Propane vehicle tanks have a working pressure of 312 psi.
- Propane vehicle tanks are 20 times more puncture resistant than gasoline or diesel tanks and are tested at up to four times their normal operating pressure.
Widespread, Low-Cost Infrastructure
Propane autogas has the most developed refueling infrastructure of all alternative fuels and the number of new stations is quickly expanding.
- There are 71,000 propane autogas refueling stations globally, including more than 2,600 public and private stations in the United States.
- As a fleet operator, you have the flexibility to install your own refueling site, and refueling equipment is relatively inexpensive, with an average cost of $40,000. Some propane fuel providers even offer no-cost infrastructure with a fuel contract.
- The low cost of fueling equipment and the fact that propane is delivered by truck make propane a good option for fleets with small numbers of vehicles in a single location, medium-duty vehicle fleets, and fleets based in rural locations.
