An added benefit is you could power your air-tools with something like this without having to convert to electrical energy. As a former off-gridder, that's actually a really big plus.
Another non conventional way to store energy is using gravity power modules (example: http://www.gravitypower.net/)
Storing hydrogen from electrolysis via solar panels also sounds interesting. Basically once your batteries are charged you start making hydrogen.
