Twice as expensive to fill as a gas car and more expensive than a battery EV to buy, all while still producing tons of CO2 by steam reforming methane to make the hydrogen? Wow, sign me up!
Hydrogen is the answer, but the question is "How can fossil fuel companies keep making money while pretending to be green?"
The technology is extremely underdeveloped. That's why it's so expensive and impractical right now. Batteries aren't ecological saints either.
Hydrogen is a pain to store and work with. Even on rocket engine that is worth millions it's almost impossible to avoid leaks.
On the other hand gas can be carried in a plastic bottle and electricity is already available everywhere.
I don't see any future where hydrogen car become mainstream.
Hydrogen is such a pain to deal with, the filling stations cost something like a million dollars each.
You can't just use normal materials to contain high pressure hydrogen - the molecules are so small that it seeps through steel and turns it brittle.
