There is only so much pumped hydro storage you can make...

  Pumped hydro seems simplest, and we often have the power plant already in place. But temperature differential storage, pressure differential storage, and creating hydrogen all seems to scale better to me.

    I've read some things about pumped hydro. The losses reduce efficiency and the amount of water you need to pump is pretty unbelievably large.
