The video says it’s 175 kwhr per kg compared to 185 for LFP that’s already used in some cars. Gold standard is Lion at 300. Volumetric is the same ratios.
So it’s usable in cars and absolutely immediately useable in homes.

Keep in mind that due to size these are only viable for industrial or utility grade storage. Not great for cars, devices, or probably houses.

Sodium batteries generally have poor round-trip efficiency. This won’t be game-changer for home or solar use unless CATL can solve that problem.
Google says 80% compared to up to 95 for LifePO4. Extra 15% cost for waste heat during charging vs 10x cheaper battery.
CATL first uses for the tech are literally car batteries. Your info looks to be outdated.
Yes, outdated info then.
Could be used at your house for solar power backup during the night?
Yeah, just double or so the amount of space you’d need for lifepo4. Good if you have some space
Are they as safe as lifepo4?
Safer.

Aren’t the current models only about half as dense as lithium Ion?
Taking up twice the space for a tenth of the cost seems like a pretty acceptable trade-off for the house scenario

Yes, it’s a great trade off, for particular applications.
