Look into hydrogen production from water electrolysis, if you're really producing a significant surplus.

    There is no meaningful way I can do something with hydrogen outside of as a feedstock into another process.

    Things I've considered that would help me, running a gravel crusher, or if there was some scaled down hauber Bausch machine. I use a significant amount of gravel and I am always in need of fertilizer.

    You can run an ICE on hydrogen, with some minor modifications. If you have enough space you can store the produced hydrogen at near atmospheric pressure in a gas holder/gasometer: https://en.wikipedia.org/wiki/Gas_holder

    As to nitrogen fertilizer, there have been recent improvements in air nitrogen fixation by way of an electric arc/plasma: https://duckduckgo.com/?t=ffab&q=nitrogen+fixation+electric+arc&ia=web e.g. https://pubs.rsc.org/en/content/articlehtml/2021/ra/d1ra01357b
