3. FUELS AND ENGINE TECHNOLOGIES

With the goal of practicality, the transportation fuel alternatives to be evaluated in this Study were subjected to a “fit for purpose” review, based upon the defined fleet application. Factors such as the availability of a vehicle platform suitable for the fleet use defined, refuelling infrastructure, security of fuel supply, vehicle operating range, refuelling time, fleet performance experience, and economic viability were evaluated to determine if the fuel alternative was “fit for purpose” as a fuel in the specific fleet application.

Hybrid vehicles were excluded from this analysis as the vehicles currently available (Toyota Prius and Camry, Honda Insight, Ford Escape and others), primarily due to size, load carrying capabilities, and performance, are not suited to fleet use in the defined fleet segment. While there are a number of Prius’ deployed in taxi use, the platform does not meet the requirements of the majority of the targeted fleet segment at this time. Biodiesel was also eliminated from the Study due to limited availability and the premium cost of the fuel. Fuel cell and hydrogen-powered vehicles are still years if not decades away from being commercially available.
