Yeah, I think massive chemical batteries for storing excess electricity to facilitate a contrived green energy market is a bad idea.

This is why you don't use battery chemistries that can ~~thermally run away~~ autoignite in grid storage. The plant was using LG JH4 batteries, which use an NMC chemistry. I don't think that LiFePO4 cells were as ubiquitous when this plant was first constructed, so the designers opted for something spicy instead.

This shit is why you use LiFePO4. It can't ~~thermally run away~~ autoignite, it lasts longer, and the reduced energy density doesn't really matter for grid storage. Plus, it doesn't use nickel or cobalt so the only conflict resource is lithium.

EDIT: LiFePO4 batteries can enter thermal runaway, but they can't autoignite.
