Yeah, thats an interesting option. Still remains to be seen if that’ll actually be cheaper. Sounds like something that is harder to decentralize than electrolysis, which can be a downside. With electrolysis you can make the hydrogen on-site.

Lithium-cobalt is not the only chemistry. I’m optimistic about alternate chemistries in the long term. Especially now that the battery market is growing so rapidly. There are massive investments in research.

I doubt we’ll run out though. They’re not that rare. Besides, it’s a renewable resource, not a combustible one.
