We've also performed fusion in a lab. That doesn't mean it'll be viable in production at scale.
What's the annual production figures for iron air batteries, flow batteries, etc.? Sodium batteries are at 9 GWh delivered in 2025. Google tells me that flow battery capacity is 500 MWh to 1 GWh, but doesn't provide any figures on actual production deliveries (production capacity is not the same as actual delivered production). There are no iron air battery facilities currently in production, with the earliest plant trying to open in 2028 with 500 MWh per year annual production.
None of your suggestions are remotely close to operating at grid scale, and there is zero guarantee that any of them will prove more feasible than lithium based battery chemistry.
