As enthusiastic as I am about that I'd love to see grid scale storage move more towards something like sand batteries. Stuff you can buy for dollars per ton and move with an excavator seems like a better bet than lithium batteries. If we want flakey renewables to be the backbone (which we should)...then we needs serious scale on storage side. Batteries for voltage regulation and quick response is good though
