Sodium batteries?
BTW that’s the wish for trend line, $10/kWh right?
As is mentioned in the article 😉 What is also mentioned is the fact that battery prices are going down. Soon it seems they’ll be down to $10/kWh!

I have seen some wild priced on Ali, in your link the 75Ah and the 210Ah are priced the same, so I guess it’s for the smaller one, 30€ for ~0.225kWh or 133€/kWh.
Could be wrong ofc, but it sort of fits what I thought it would roughly be.
TropicalDingdong@lemmy.world 6 months ago
I mean even ~133/kWh…
Whats an average, perhaps even gratuitous, level of consumption per household? 24kwh if you are running a clothes drier and an AC nonstop? Lets go nuts, say you are a DIY enthusiast and hosting your own servers, so 36kwh daily.
3192€-4788€ to be and you can be effectively energy independent with a small solar system.
Triple that and you are truly energy independent are any where south of the English channel. I mean obviously its money out of pocket, but its a fixed cost that you pay now, instead of a variable cost that continuously goes up. It just seems basic.

There’s also alot of new battery tech on the way.
There will be a market for batteries at home, and they will exist with the best suitable tech for it - and it’s probably not lithium.
How many years, I dont know. What will it be, and who will do it, no clue. Otherwise my stock portfolio would look better if I knew these things haha.

I wish the second-hand battery market were more lively. Using half-worn car battery packs seems optimal for home use.

I’m not putting cobalt based (NMC or NCA) batteries inside my house. Thats nearly exclusively what car battery packs are. Thermal runaway is too great a risk to bolt that much energy to a wall in the house. I am comfortable with LFP in the house though.

It is. Some of them are getting snapped up to help with powering factories.
I think this is car companies using the incoming battery packs from replacing worn out packs. Time to look it up…
