What alternative do you propose that does not use electricity? Ox carts?
Some of your observations are somewhat off. For one power plants achieve near 90% efficiency of energy production, so shifting the energy usage(and by extension the pollution) there makes far more sense.
Second you have no idea what a hydrogen fuel cell is. You are thinking of a hydrogen POWERED car. Which would burn hydrogen instead of petrochemicals. A hydrogen fuel cell generates electricity from the fuel source.
Battery technology is improving. we are able to store more energy in smaller spaces.
So no, I don't see this as nonsense.
