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.
sell energy buy gravel, we invented money for this very reason.
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
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.
Yeah but I can't turn electricity into clover
Oh hello! You posted on /r Technology and latelly /r Collapse before it all went to shit! I'm a big fan of you!
Oh, hi. Glad you liked my posts. The latest /c/collapse incarnation on Lemmy (we've had to move twice) is on https://lemmy.zip/c/collapse btw.
