The greener option is to not produce something to store energy.

If you know mechanics in your area, repurposing old car batteries (who're not powerful enough to start a car anymore but are powerful enough for quite many other things) is the greenest thing. If you have a water stream nearby, using excess energy to pump the water upstream (so it passes through your generator again when there is no excess) is the greenest thing.

We all have to remember there's not a one-size-fits-all solution because energy is never green. The greenest energy is the energy we don't use. Next greenest thing is to repurpose anything you find to produce/store energy, because whether we're talking about solar panels or battery or whatever, there's nothing green about that at all. So the greenest is a very localized solution depending on local context.

Do you have some resources on how to do that and what performance this could provide on a small scale?
