What I would like to see, however, is other fuels made from Nat gas. There is a dozen uses for using Nat gas as a fuel base instead of compressing it to 6k lbs. What I think would help would be to decide on a fuel that could be made from oil, Nat Gas, or coal to use in motor vehicles and build cars to use that. Diesel comes to mind. The Nazi's had very little oil they didn't steal from other countries so they fought much of the war with coal fuels. I'm no expert, but I hear there are many fuels that can be made from Nat gas. With abundant Nat Gas and coal in the US, we would be energy independent.
That is my concern, basically, too, about NG used in personal vehicles: the nature of the fuel means a lot of pressure is required, and that means a lot of things could go wrong. Also, I think NG vehicles have less range per tankful than do gasoline vehicles.
I’d otherwise love an NG vehicle option, assuming, of course, that a decent nationwide fuel-delivery system can be brought online ...
Keep in mind you can buy a natural gas compressor and refill your car at home. With a multifuel conversion, natural gas and gasoline, you can buy which ever is cheapest at the time.
Of course with home fillups, you need to call the tax folks and figure out how to pay the road tax. I’m sure everyone with a home fill staion will do that otherwise the fuel would be really cheap instaed of just cheap.
But your point of price is my reason for not pursuing a propane powered vehicle, no real price savings.
Other fuels can be made from Natural Gas, as long as you want to pay gasoline or higher prices.
