We had a fleet of propane powered GSA cars for years at the EPA. They were OK but the issue, which still remains, is energy density. How many BTU's per pound of fuel. Unless you have a HUGE tank you have to fill up a lot, which may be an OK trade off with today's fuel prices. The higher pressure you can store it the better the energy density - but the more dangerous it is. It may not be a significantly cheaper alternative when the energy density thing is factored in.
Oh, and it isn't "cleaner". Lower in HC and CO, higher in NoX, which is harder to clean up. As always, a trade-off.
