Also seems worth mentioning ESS. https://essinc.com/ https://essinc.com/ They're a bit further along (scaling up from low-volume production, some installs in the wild) with a different approach to the use of iron (flow batteries).

ESS should not be mentioned except as an example of how prone the green news cycle is to fraud. As I detailed last year, their claims are highly dubious: https://news.ycombinator.com/item?id=31430227 https://news.ycombinator.com/item?id=31430227 (previously I misspelled the last name of Sri Narayanan as "Narayan", for which I belatedly apologize) And that prediction was substantiated when they were subject to a class-action shareholder lawsuit in February involving a fabricated customer which was actually a subsidiary: https://www.bloomberg.com/press-releases/2023-03-10/the-law-offices-of-frank-r-cruz-reminds-investors-of-looming-deadline-in-the-class-action-lawsuit-against-ess-tech-inc-gwh https://www.bloomberg.com/press-releases/2023-03-10/the-law-... The other shoe has yet to drop, but I suggest that any battery company without publications should be considered with appropriate salinity.
