The Hydrogen tank for the Toyota Mirai literally has a replacement date of 10 years. And that's not a maybe, it has to be replaced for safety reasons.

Modern Batteries last 10 years easy. Even the abused leaf ones with no thermal management last fine. It will not be any issue

Could be, but I bet that hydrogen tanks is much cheaper, easier to produce and recycle. Also doesn't require rare earth materials.

They're not comparable at all, I just said it as a reaction. The battery is more comparable to how often an engine completely dies. It doesn't, really. Especially the newer ones with proper thermal management.

The tank is cheaper, sure. But the hydrogen itself and infrastructure isn't, and hydrogen isn't even really green 95% of the time. But that's a whole different topic.

How is solar hydrogen collection stations that pull hydrogen out of the atmosphere not green?

It's wasting solar that could be used for better things.

But without the loss of solar to hydrogen convertion.
