i think you mist out the real reason why hydrogen cars are a bad idea.
-The Energy Efficiency is about less than 30% from electricity production to the weels on the street.
-The scalebility is limited. The highest efficiency they have with an 20x20cm membrane.
Yes you can stak them in big clusters but the efficiency is getting even worse with this, cause of the heat production like an engine.
-Fuel cells like constant power output. So you need a batterie between the drive train and the fuel cell. when you drive up a hill you need more, or in the city with constant stop and go.
That makes fuel cell cars more complexe than batterie electric car and not really competitive.
-you named it with green hydrogen. Its less than 1% produced on this sector. And because of the bad scalebility its expensive to plant them near wind oder solar farms in a large quantity.
even the technology is known for over 50 years, the problems havent changed since.
If you have questions, feel free to ask. I´ll try to answer with my english :)
