Reply to comment by gnocchicotti in Scientists lower price of lithium's best competition - flow batteries - by 20%. Makes the battery effectively equal to or cheaper than lithium ion when spread over 30 years (flow battery lifetimes are effectively infinite with light repowering efforts). by PorkyPigDid911
I thought this, but pricing it out with a GC it came out about even (replacing asphalt several times versus standing seam once). And cost to remove/replace solar is a little confusing to, since the solar technology will probably be way better in another 10-15y.

Right, iron-air are designed for multi day grid storage. For example, when it's cloudy for a week, these batteries discharge previous excess solar back into the grid. More about Form Energy's batteries if that's what you were thinking of.
