Green Fleets - British Columbia

Many fleets are considering ways to lower their carbon and smog related emissions.  For some fleets alternative fuels can be an option to reduce both types of emissions, and in some cases, also lower their fuel costs.

Some fuels such as biodiesel and ethanol blends can be used in conventional combustion engines with no modifications to the engine or fuel system.  Other alternative fuels such as propane or natural gas, require some modifications to the engines as well as the fuel handling and storage systems. All types of fleets in BC have used each of these fuels with success.

Hydrogen is a new fuel being used in limited application in British Columbia. Fuel cells are the primary method of using hydrogen since the only emission is water from a tailpipe. The technology is still in early stage development but a major demonstration has been announced in time for the 2010 Olympics.

Key factors when considering using an alternative fuel include:

• Comparative fuel costs
• Conversion and storage costs, if any
• Emissions performance
• All weather operability
• Fueling logistics including vehicle range, frequency and location of refueling
• Maintenance and operational costs and training
• OEM vs. aftermarket conversions
• Lifecycle emissions in addition to tailpipe
• Availability of accessible, high quality fuel
