The entire difference is undoubtedly tax.
With no tax, propane or methane is a more expensive fuel.
The only real advantage is these fuels is that the combustion by-products have lower levels of sulfur and nitrogen compounds. There's less contamination of the motor oil, and engine wear is significantly reduced. Since a car motor usually outlives the car, this is actually no advantage at all. For a city bus, however, the lifetime maintenance costs could be significantly lower, and the reduced range wouldn't be a problem.
