Converting the electric grid to nuclear or other “green” sources may be more practical than converting to another type of liquid fuel.
How?
What if you have to drive more than 40 miles?
Drive for 40 minutes and stop and recharge for two hours or more?
America is a BIG country.
40 miles doesn’t cut if for anything but “short” (by American standards) commutes.
Hydrogen would give us the range and refuel capabilities that more closely align with our current driving infrastructure. Electrolisys via nuclear power would be very “green”.
Electric cars are, essentially, a dead end.
