> I agreed with that before Tesla's Big Battery

Tesla's battery isn't really grid-scale energy storage of the kind you'd need to do 100% renewables. It's more for smoothing out fluctuations in the grid than for filling in for intermittent sources when conditions are poor.

If the gamble on renewables works out, it will be because of geological hydrogen energy storage. That's the only way to get country-days worth of storage at a price that's actually feasible (if it works in practise like it does on paper).
