Solar/wind + battery storage is cheaper than natural gas and a hell of a lot cleaner. It makes no sense to go for a more expensive, dirtier form of energy.
there's not enough lithium on this planet to store enough energy for like half of europe nevermind entire world
you know how to do this the right way? use pumped-storage hydropower. need more? build more, then dump power into heaters (or better yet heat pumps) on demand from grid since fossil fuel heating will be replaced anyway. (we're nowhere close to this, but it can sink a lot of energy quickly while not using it at some other times)
This is a good use case for sodium batteries. They're less energy-dense so not great for vehicles, but for a stationary application like this they're perfect.
yeah this is fine, but these need to run at high temperatures last time i've checked. that makes it a bit more complicated to use
Sodium electric batteries, like the type that CATL developed? Or do you mean hot molten salt thermal batteries? Because I think the other poster is referring to the first kind.
i thought sodium batteries need low hundreds C for ceramic electrolyte to work. i stand corrected
e: CATL made sodium-ion battery, i was thinking of sodium-sulfur battery
