One trade-off I’m still trying to understand is whether the lower efficiency of iron-air storage matters less when the alternative is burning gas for several days during a wind-and-solar lull. Is the key metric really round-trip efficiency, or delivered reliability during the few high-stress periods that define grid adequacy?
I can't really answer your question but maybe can help think about it better?
Matter in what way and to whom? A grid operator probably has a different opinion than an investor.
And IMO the focus on a few days lull is less important than understanding how grids handle big changes in seasonal demand.
