The Polk County Sheriff’s Office will reduce its fuel costs by more than $20,000 annually with the new propane-powered patrol cars. Conversions and fueling are provided through Alliance AutoGas, with West Coast flagship fuel provider Blue Star Gas at the helm. Converted vehicles include seven Ford Crown Victorias, two Chevy Tahoes and one Ford F-350 pickup truck.

Sergeant Mark Garton of the Polk County Sheriff’s Office said they were looking for a way to save money on the fuel costs since patrol cars average almost 25,000 miles each year. Now, not only will officers save money on fuel costs at the pump, there’s also a 50-cent-per-gallon federal alternative fuel tax credit that will go back into the pocket of the county–and back to services that benefit taxpayers.

Deputies haven’t detected any loss in vehicle performance with the propane-powered cruisers, and they’re also enjoying the versatility offered by the bi-fuel Prins VSI autogas system Alliance AutoGas uses for vehicle conversions.

“The ability to switch back to gasoline is a tremendous option for our fleet because in an emergency situation, we not only have a full tank of propane but also a backup full tank of gasoline,” said Sergeant Garton.

Sun Ray was the first business in the Columbus area to invest in more eco-friendly dry cleaning methods, and now it’s the first dry cleaners locally to operate autogas vehicles. The new autogas vans will not only reduce greenhouse gas emissions and harmful pollutants, they will help reduce the fleet’s fuel costs as well.

Alliance AutoGas provides fleets everything they need to launch and maintain a successful propane autogas program, from vehicle conversions and on-site fuel station installation, to staff safety training, ongoing technical support and a reliable year-round fuel supply. Sun Ray Dry Cleaners joins many other fleets in Georgia that have switched to autogas through the Alliance program, such as the Muscogee County Sheriff’s Office, which has converted more than 30 patrol cruisers to propane autogas.

Propane autogas is the most widely used alternative fuel in the world, powering 18 million vehicles globally. Autogas is more affordable than gasoline, produces significantly fewer greenhouse gas emissions and 98 percent of the U.S. autogas supply is made in America. Fleets operating on propane autogas are currently saving upwards of $2 per gallon on fuel versus gasoline.

There are approximately 160,000 propane auto­gas vehicles on our nation’s roads and highways, making autogas the most widely used alternative fuel for transportation in the U.S. That is some­thing to be proud of. So is its impressive safety record.

While vehicles fueled by propane autogas have a long history of performing safely under all operating condi­tions, some people have the perception that these vehicles are more dangerous than traditional gasoline- and diesel-powered vehicles. That perception is inaccurate.

When it comes to the transportation of children, school fleet directors know that propane autogas school buses are the safe choice. That’s because propane autogas school buses have bracket systems that help hold the fuel tank in place. In school buses, propane fuel tanks are located between the bus frame rails, providing added protection to the tank and thereby increasing the safety of the passengers.

School buses that run on propane autogas meet all con­ventional bus safety standards, plus additional standards required for alternative-fuel vehicles.

Propane autogas engine fuel systems in all types of vehicles are fitted with safety devices and shut-off valves that function automatically if the fuel line ruptures. All tanks are equipped with a valve — or combination of valves — in the liquid outlet connection that has manual shut-off, excess flow, and automatic closure features. The valve assembly prevents the flow of fuel when the engine is not operating, even if the ignition switch is in the ON posi­tion. The vehicle pressure relief valve must be vented to the outside of the vehicle, and all fittings must be vented to the outside if the tank is in an enclosed area, such as a trunk.

It’s Not Hollywood

Propane autogas tanks are 20 times as puncture-resis­tant as gasoline tanks, so they are more durable in a collision. They can also withstand up to four times as much pressure as a gaso­line tank. Propane containers are much less vulnerable to puncture than moviemakers would have us believe. James Bond, for instance, causes an explosion by shooting a propane tank using his 9mm hand­gun in “Casino Royale.” But tests show that it doesn’t work that way in real life, as an episode of the television show “Myth Busters” makes clear (the segment is avail­able for viewing on YouTube).

Another safety feature of propane autogas is that it requires a much higher temperature to ignite. Gasoline and diesel fuel will catch fire at temperatures as low as 495ºF, whereas autogas requires a temperature of at least 920ºF to ignite. The chart below illustrates the flammabil­ity range of propane autogas and other fuels.

Many organizations develop and implement codes, standards, and regulations for the safe use of vehicles that run on propane autogas. The regulations are con­stantly reviewed, updated, and improved to ensure that all new vehicles and vehicle technologies are as safe as possible.

The American Society of Mechanical Engineers (ASME) is responsible for rules governing vehicle tanks and piping. As an example, the tanks in all vehicles fueled by autogas are constructed from carbon steel in accordance with a code developed by ASME. The National Fire Protection Association also develops and implements codes and stan­dards for propane autogas storage systems, dispensing sta­tions, and vehicle systems.

Propane autogas is indeed a safe fuel when properly stored, transported, handled, and used. Several factors help ensure its safety: the fuel’s natural properties; the quality construction of fuel system components; stringent codes and regulations; and the industry’s extensive train­ing and safety-awareness programs.

Darren Engle is director of marketing for Blue Star Gas, which serves Northern California, Oregon, and Washington. Blue Star Gas is advancing the use of pro­pane autogas, and is a member of Alliance AutoGas. Engle serves as chairman of the Propane Education & Research Council’s Research & Technology Working Group, and travels the country training fleet managers of both private and public entities on the economic, safety, and environmental benefits of propane autogas.

It’s nearly impossible to imagine this massive country of ours functioning without passenger vehicles, trucks and bus fleets–we need transportation to get us to and from work, to deliver goods and services, and often just to make it from place to place across the suburban sprawl. However, there are ways we can lessen the environmental impact, the “carbon footprint,” our vehicles are leaving behind. Step one is walking and driving more, and also taking public transportation when possible. Drivers who can afford the upfront cost of alternative fuel and advanced technology vehicles can also do their part to protect the environment by purchasing cleaner vehicles.

America’s fleet industry can make the most difference in improving the air quality of our communities, right now. With thousands of vehicles on the road every day, vehicle fleets can significantly reduce greenhouse gas emissions and harmful pollutants by running on domestic clean fuel like propane autogas, natural gas and biodiesel.

Propane autogas is among the lowest total carbon emissions fuels, showing at least a 20 percent reduction in emissions versus gasoline or diesel. In fact, autogas is so much cleaner than conventional fuels, fleets often need less maintenance (think fewer oil changes and less vehicle down time!) and report their propane-powered engines actually last longer. Also, fueling up with propane autogas is greener than gasoline because autogas fuel stations are spill-free with zero-emissions.

Worried about being able to refuel your clean propane autogas vehicles? Don’t be. There are currently more than 2,500 autogas fueling stations throughout the U.S., and that number is growing every day as more fleets switch to this American-made fuel. And with an affordable cost of implementation, it’s financially viable for vehicle fleets to get up and running on clean-burning autogas today at little-to-no upfront cost.
