Kinda hard to do that when the moon is only 1/6g. You'd have to raise the same object 6 times higher to get an equivalent amount of potential energy storage than you would on Earth.

Or make the object 6 times heavier.

Big thing + any motion whatsoever = a surprising amount of energy. And we can capture that energy. Or use energy to move the thing to a higher potential, and thus store said energy for use later. It’s just physics.

Of course you'd need even larger equipment to be able to handle it. One way or another things have to scale. For sure solar or nuclear power are the more practical options for now.

I thought we were talking about long-term energy storage.

Kinetic storage devices are WAY simpler and WAY longer lasting. A big lunar rock suspended in a vertical shaft a couple hundred meters deep is probably going to have a higher MTBF than even the most advanced batteries or capacitors.
