That's interesting! I had no idea about sodium batteries! Thank you!
Nickel-iron and lead-acid batteries have a lot of historical use for grid-backup applications, and lead-acid ones are still cheaper than lithium, but I don't think the resources are there to scale to an all-solar civilization. Nickel-iron batteries might be cheaper (the resources are a lot more abundant) but nobody sells them anymore I think?
There are whole classes of all kinds of energy sources that haven't been industrialized yet, including, to a great extent, nuclear energy. EGS comes to mind. The critical thing about PV is that it's crossed the chasm to mass production and the ensuing price drops. So I think it's crucial that current lithium production won't scale to the needs of an all-solar grid — but that oceanic extraction could.
