Oooh. Very interested in this. I was thinking about trying to build my own gravity battery, but my back of the napkin calculations for the mass and height are nutty. I don't think a small scale home-size device would be viable...

Yeah. My crazy idea now is to drill a well, seal it with concrete and use it as CAES, and then put a small Gravity battery inside of it... But even then, the gravity battery would add a negligible amount of energy storage... It's just really hard to find good energy storage at this scale.
