How about a mixture of batteries (redox-flow, LiFePo, NaFePO, iron-air, Li-Ion), thermal storage (porous volcanic stone, heated water, liquid salt), mechanical storage (giant rotating masses, compressed air), pumped hydroelectrical storage, power-to-gas or power to liquid(hydrogen or ammonia) and creating interconnected power grids?

That should do. Would not create a single point of failure and prevent having everything in the hands of probably a single entity.

While I agree that we need to pursue energy storage solutions In addition to investing in renewables and nuclear. I feel that it would be staggeringly inefficient to have to harvest and store and then redistribute power at the scale you are describing. The power loss and transmission alone from generation to battery to end user would be over 30% most likely. And at that point It's far more efficient to directly energize the consumer with an on-demand source such as a nuclear power plant.
