>I mean, they are all energy storage, but they aren't the chemical based batteries I thought you were talking about. Good to clear up confusion. I mean batteries in the general sense, not just based on chemistry. >But, in general, they are technically sound and can be scaled up with sufficient investment and demand. So far that hasn't been shown to be true. This is very much an open question, leaning towards 'no' because NOBODY got that level of storage working.
