We’re seeing the reshaping of the entire global energy system. Either we jump on the train or get run over.

More like a few decades, if ever. Battery production is estimated to reach 6.8 TWh per year in 2035 [1]. But only 12% of this is expected to go to battery storage systems, yielding just 800 GWh. 12 hours of storage worldwide at current electricity demand is 30,000 GWh. And by 2035, electricity demand is going to be more than that, as transportation and industry is increasingly electrified and migrated off of fossil fuels.
To reiterate, this is just for 12 hours of storage. Seasonal fluctuations can depress renewable generation for days or even weeks.
