    pumped hydro is pretty slick but incredibly dependent on geology and ecosystem.

    Thermal storage is a similar vein, you can even use water, we do use water for this even. Compressed air as suggested, i believe there’s a mine somewhere in the US that’s used a compressed air storage plant. And of course, motion, flywheels go hard i hear, but i find those to be less preferable, even if high energy density. I imagine those would work better at scale.
