Positive Environmental Impact

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 netof the known difference
in energy content –propane yields approximately 76% of
the energy values of gasoline or expressed another way, 1.3litresof
propane yields the equivalent energy of 1.0litreof 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 “SarniaGate”
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 emissionsmodel 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 GREETmodel, the Chart
below shows the emissions outcomes of near-term technologies using
LPG vehicles relative to baseline gasoline vehicles fueled 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 lessparticulate 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 Refueling Advantages
- Propane refueling 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 codesand 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. Anyless than that and the mixture is too lean
to burn; any more than that and the mixture is too rich to burn.
