Nope. You've got livestock (hogs, poultry, etc), or you've got fossil-fuel-based Haber-Bosch. I'm not even really aware of any science fiction concepts "other paths". The Haber-Bosch process needs hydrogen, as you said in your first paragraph. Hydrogen can be made directly from water by electrolysis with renewable or nuclear electricity. This was already done on an industrial scale in the 20th century, with hydroelectric power used to produce hydrogen for ammonia: "1921–2021: A Century of Renewable Ammonia Synthesis" https://www.mdpi.com/2673-4079/3/2/11 That's how to use the Haber-Bosch process without fossil fuels or livestock. |

Nice. You've just made one of the most energy-intensive necessary industrial processes even more energy intensive. Even while you're doing your best to demolish whatever baseload power we might still have.

Got any spare hydroelectric? Any more rivers you want to dam up? Maybe you can decommission a few more nuke plants and replace them with brown coal.
