    Yeah, for gridscale power in areas without enormously expensive land prices, cheap might beat out dense in terms of battery tech usability. Lithium is still best for applications that require energy density (EVs) but for grid storage I can see bulky, cheap, resilient/reliable batteries make more sense as a long-term investment.

        Just requires a hill that is big enough, two basins that can hold the water, and then of cause we need all the water.
