Low Fuel Costs

• Fleets operating LPG-based vehicles over the past eight years realized annual average fuel savings of 43% compared to similar vehicles based on gasoline
• The above savings are net of the known difference in energy content propane yields approximately 76% of the energy values of gasoline or expressed another way, 1.3 litres of propane yields the equivalent energy of 1.0 litre of regular gasoline
• Regulatory emission commitments in North America and the world are driving refining costs for gasoline higher and hence future gasoline prices could be forced higher which could further extend the current differential compared to propane
• There are substantial facts and arguments to support the position that the current price differential and related historical economic benefit of fuel cost advantages of propane will continue into the future
• The average savings with propane since January 1994 has been approximately 25 cents per litre on an energy equivalent basis under feasible and effective fuel procurement strategies

Supply Security

• Propane is a bi-product of both natural gas plant and oil refining processes
• Fortunately Canada is very deep in both gas processing facilities and Natural Gas reserves
• With a large and expanding market for natural gas available in the U.S., an abundant supply of propane for Canadian consumption is assured in the year 2000 Canada exported via pipeline networks more than 3.1 trillion cubic feet of natural gas
• Consequently, 85% of Canada's total propane production was derived from natural gas processing

Canadian Sources of Propane Production

• Wholesale supply prices are set by producers such as BP Canada and Shell Canada at major supply points in eastern and western Canada. The posted 'Sarnia Gate' and 'Edmonton Gate' FOB prices establish the standard for producer prices to wholesale distributors and propane marketing organizations in eastern and western Canada respectively
• Seasonal spikes can be severe but history indicates that while these are sharp, they are usually short-lived
• Fleet managers can minimize the risk inherent in these seasonal spikes by entering into medium to long-term 'pre-buy' arrangements for estimated fuel needs during price-sensitive periods
• Other options available include becoming a member of a fuels buying group and leveraging group buying power with wholesale suppliers
  
  

Positive Environmental Impact

Numerous historical studies have drawn similar conclusions regarding the environmental advantages of propane versus gasoline.

Now the Department of Energy in the U.S., through Argonne Laboratories, has made available an interactive, dynamic comparative emissions model for estimating the complete life cycle impact of various fuels on the environment. This Greenhouse Gases, Regulated Emissions, and Energy use in Transportation model, referred to, in acronym form, as 'GREET'. allows researchers to evaluate various engine and fuel combinations on a consistent fuel-cycle basis.

Based on the results from the GREET model, the Chart below shows the emissions outcomes of near-term technologies using LPG vehicles relative to baseline gasoline vehicles fuelled with conventional unleaded gasoline. The numbers clearly indicate that LPG (propane) offers significant emissions benefits compared to gasoline vehicles across the full spectrum of major emissions elements.

Other Propane Advantages

• Longer Engine Life, Less Maintenance
• Propane is a uniform fuel which has a consistently reliable 20-25% higher octane value than regular gasoline without the need for fuel additives the variation in octane values which occurs in gasoline amongst a range of suppliers, additives and production quality ranges will generally tend to shorten engine life
• The result of consistently higher octane values is cleaner burning and more consistent ignition dynamics with less overall wear and tear (knock) on major engine components
• Cylinder wear is also lessened since there is no liquid fuel to collect on cylinder walls and wash down during fuel-rich starts
• Engine oil stays cleaner longer as propane combustion emits less particulate matter than gasoline
• Overall the result is extended engine life often 1-3 years longer than gasoline-powered engines -and the need for less maintenance

On-Site Storage and Refuelling Advantages

• Propane refuelling storage and dispensers can be installed on-site above ground which substantially eliminates environmental contamination concerns for fleet operators this means typically less risk and less cost for these facilities compared to underground gasoline storage systems
• Propane's pumping rate, 45 to 50 litres per minute, is comparable to that of gasoline. Propane is delivered through a sealed system, with a simple screwed connection thus protecting the environment. Evaporative emissions from gasoline have negative environmental effects.

Safety

• Propane has an enviable safety record due to the stringent codes and regulations developed by the propane industry in conjunction with the American National Fire Protection Association (NFPA).
• Propane has a narrow range of flammability, meaning the propane/air mix must contain from 2.2% to 9.5% propane vapour to ignite. Any less than that and the mixture is too lean to burn; any more than that and the mixture is too rich to burn.
