No, there is pumped storage. Honestly, despite the plethora of start-ups claiming to have a solution (sodium batteries, molten-salt, etc) The only really proven way to store electricity for later is pumped storage, but that relies on geography (hills) which not everyone has. Batteries are great for phones, and cars but they simply don't scale to countries.

California is doing pretty good with their battery storage. And if all the electric car batteries get old we can use them as stationary grid storage.

That is actually very impressive. Thanks! I remain a bit skeptical as its only 1/5th of what they need and it's only one region of one (rich) country. Still, 10GW of lithium battery would be one hell of a fire ;-)

South Australia implemented a 100mw battery for their power system in 2016
