The only roadblock is government. PERIOD
I would gladly convert my cars to dual fuel use for NG and Gasoline as the conversion kits have been on the market for years.
However, there is only one NG filling station in Western New York which allows us lowly citizens to use. The others (16 or 17 I believe) are all owned by NY State (which should mean us but it does not) and we are not allowed to fill our vehicles there. Only DOT vehicles are allowed.
If it were not for NY State this would be a no brainer. You could use NG when it was available or simply flip a switch and run on gasoline if you ran out of NG. In my area I would spend most of the time on gasoline so the conversion would not make much sense.
I’m converting my house to “duel fuel” - ie, everything that can practically be NG instead of electric is going that way.
And for the rest, I’m putting in a NG generator,
for when “electricity prices necessarily skyrocket”.
They’ll probably never get to the point where it’s cheaper to make my own than to buy off the grid, but what if the electric grid simply isn’t there?
Have the govts(state and federal) figured out a way to tax natural gas as a transportation fuel ?
This might be the road block. IF huge amounts of the public switch to this fuel, the govts. lose a big revenue stream.
Are there laws in place to tax this on the state and federal level ?
If you can fill your automobile at your house or place of work , how does the govt. tax you on it ?
