Not nearly as much as required to produce batteries.

Apples and oranges. You would need to compare energy needed to produce the tank and fuel cell to the production of batteries.

Sure but in that case please add energy costs for recycling the batteries bs recycling tanks for hydrogen. And I do not see how batteries can win in this race.

Hydrogen embrittled metal isn't very recycling friendly.

And how long is the lifetime?

A battery lasts for many years. H2 is used more or less immediately.
