    Can you? To store the energy you need to pump up; to use it you need to flow back down. Where is the ‘down’ or ‘up’ from a mine shaft?

    I’d also question if the volume would be worth it.

    Edit: maybe you are thinking compressed air?

        I guess I wasn’t clear where on the surface the storage is. Do they still make a dam type area to store the ‘high’ water, or is it just a different part of the mine which is closer to the surface?

        I was able to find some mine numbers… yeah; insane. Especially something like an open cut mine which is functionally already lake shaped.
