Sodium-ion batteries are not hype though, they are in production use in multiple industries already. They are generally superior to Lithium based batteries in all regards, with the exception of having a bit lower energy density. An equivalent LiFePO4 battery might be 70-80% of the size for the same storage. It's not a big deal for large applications like cars and solar storage.
Yeah, the advantages of all these sodium batteries, in my mind, is that they are stable and rugged enough to build up a backbone of a energy storage system for a grid. I'm seriously thinking about them for my house, in the UK.
