Hell yeah

I can't wait to see this headline again but about a bigger battery somewhere else

Nice. This seems to be the future that solves a lot of problems. Right now in Australia, we’re seriously entertaining building nuclear power plants for the first time ever, to provide base load power that renewables allegedly can’t. Large sodium batteries could help us avoid that.

It's not just base load, turbines also provide grid stability. All the quick fluctuations as people turn things on and off are hard to load balance with solar, wind, or battery. A big spinning turbine has a lot of inertia. That helps keep thr grid at a constant frequency. As solar gets bigger and bigger we might need big solar powdered flywheel generators just to stabilize the grid.

Lol,

Batteries are perfect for load balancing.

Please, know your facts

[–] Gormadt@lemmy.blahaj.zone 13 points 4 months ago

The main issue with using batteries for load balancing is the massive resource investment required for them at a grid level, BUT that's more of a concern with lithium based batteries due to a number of factors. Sodium batteries use way more easily accessible and abundant materials.

NGL I'm hella fuckin hyped about sodium batteries vs lithium batteries.

[–] themurphy@lemmy.ml 5 points 4 months ago

Batteries can't stabilise frequency. If the frequency changes too much, the grid will go down.

You literally need a giant spinning turbine for this.

It's pretty basic energy engineering, and is not related to load balancing.
