I'm still kind of shocked lead acid is faring so poorly when it comes to grid storage. One of the oldest (the oldest?) battery chemistries, well understood, really cheap, mostly safe, simple, durable, serviceable, recyclable. (sidenote, submarine warfare was, for decades, powered by lead acid) It's chief disadvantages are low power density and low power to weight ratio, neither of which matter for grid storage. It just seems to have all the hallmarks of traditional industrial solutions. But, of course, lithium ion has the same advantage ubiquitous silicon semiconductors have- massive, massive economies of scale and endless R&D dollars.
