But hydrogen infrastructure isn't better long term than regular electric and battery infrastructure. You need quite unique circumstances like being highly dependent on high energy density while being located in a place where you're far from an electric grid. Like an island in a stormy place (without access to wave power, etc) or long haul trucks out in nowhere or electric airplanes. Almost anything else should use better options

Not clear on what you’re trying to say here. The energy generated from a fuel cell is electricity. The entire fuel cell assembly is essentially a battery, using hydrogen and oxygen as the electrochemical components.

But, I think you’re trying to argue that one is better than the other. To that all I can say is we all are just getting out of being locked into a singular infrastructure (combustion engines) for the last 90 so years, it’s probably best to invest concurrently in multiple alternative energies instead of putting all of our eggs in one basket. Hydrogen has some strengths where lithium ion does not and vis versa. I’d assume it would be best to diversify so if one fails we have multiple backups. Kinda like investing money, don’t put all your money behind one horse.

Storage and transfer are the complicated parts, remember that hydrogen leaks VERY easily (even right through most metals) and require very high pressure. It's never going to be the cheapest option unless you're weight constrained
