...yes, in principle I am with you. But, I think you agree, if someone comes up with a energy storage technology, which addresses the current limitations, there is no need for hydrogen anymore. I do not want to compare petrol vs hydrogen - the difference is not that big (transport, storage, explosive, etc.). Compared to a battery, hydrogen has disadvantages. But don't get me wrong I do not talk about lithium batteries - they are dangerous too...
The question in this area is, if hydrogen is the better energy storage medium or will there be a device (hemp, graphene, other 2d material) that is more efficient. Time will tell.... btw. Elon Musk doesn't see hydrogen as an efficient solution but others do:
