Correct in a round about way. Hydrogen is a clean fuel period. Where we run into a problem is it is created out of water. Hydrogen is cheap to produce and generators are relatively simple to build. There a multitude of problems with this scenario. No profit to be made unless there is handouts. Hydrogen is highly volatile and people are stupid, enough said. Now how to meter it for combustion is the challenge that has never really been harnessed. It has been successfully done on a limited basis for fixed speed engines but not for a range like automotive application where you have stop and go traffic. For these reasons it is the next great Rona scam to make the rich richer and the people poorer.

And when it is combusted to produce power for a car the “waste product” is water. Having grown up mostly in very cold climates I have to wonder whether much of that waste water will end up as very thin but very slippery black ice on the roads travelled in cold climates.
It could well be the GOOD OLD CURSE of UNINTENDED CONSEQUENCES.
