I read some interesting things about crazy sounding technologies like vanadium flow and iron batteries. I think we're at most 10 years away from storage being not fully solved, but becoming an enabler more than a bottleneck.

Vanadium flow batteries are more expensive and less durable then LFP and the price won't come down because Vanadium is an expensive metal to get.

They were interesting but the whole concept just has problems and has for over a decade at this point despite commercialisation efforts.

Same story with iron: it's out there, but the scale on LFP and likely Sodium is going to shoot right past it.
