    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.

      I know on a small garden scale, clover is a very good companion plant because it affixes nitrogen to the soil. It also acts as a ground cover to reduce moisture loss and suppress weeds, and on top of all of that it attracts bees.

      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

        Yeah I’ve seen the plasma arc thing. I’m vaguely associated with some in the agrovoltaics research community and have considered reaching out. It’s not available to retail consumers yet
