Estimated needed storage for Germany to go full renewables is around 12TWh storage.
If i remember correctly, the biggest pumped hydro storage facilities hold about 1GWh storage. So you'd need 12 000 of these. Better start building some moutains!
Musk's australia battery plant is around 200MWh.
As you can see, we're quite a few orders of magnitude off.
Then there is hydrogen, but "power to hydrogen back to power" doesn't have a great efficiency (nowhere near the 75% of pumped hydro or 90% of batteries).
Basically, near 100% renewables is only achievable in countries with low pop density and a lot of mountains (Norway for instance).
