FYI. Hydro power has similar capacity and start up times

    Not quite - only the biggest hydro stations can generate a gigawatt or more, and their startup time is like 10 minutes.

    This project is only 500 MW here

    https://www.pv-magazine.de/2024/09/20/flexbase-plant-500-megawatt-redox-flow-speicher-in-der-schweiz/

    And other places say 800 MW

    Both of which are comparable to large hydro.

    Modern pumped hydro has a ramp up in the 10s of seconds range.

    Anyway. Same ballpark in terms of power.

    Yeah, the downside of hydro though is that you need to have a fitting space to build it. You can't just excavate a random field somewhere and plonk a hydro dam right there.

    In most places all easy spots for hydro are already taken.
