No, see, this is again the misunderstanding I’m talking about. Ammonia is made with hydrogen, period. The “large scale source of hydrogen” exists today. It is steam reforming of natural gas, and before that it was electrolysis of water.
- Johnny555 5y agoThis is the misunderstanding I'm talking about: "steam reforming of natural gas", is the same as "fossil fuels". If you're going to rely on some future development where the hydrogen doesn't come from fossil fuels, then you can also declare that gasoline and diesel are not fossil fuels since non-fossil fuel sources exist for both.
- Robotbeat 5y agoI mean, there’s lots of green hydrogen production in California right now. Clean electric synthesis of hydrocarbons is most certainly possible but a lot more expensive, complex, and inefficient, and I’m not aware of any place you can just buy it, unlike green hydrogen in places like California. Hydrogen electrolysis used to be the dominant method of making ammonia hydrogen. Hydrogen electrolysis is simple enough there’s a Kiwi Co tutorial on how to do it with household items: https://www.kiwico.com/diy/stem/quick-easy-experiments/splitting-water https://www.kiwico.com/diy/stem/quick-easy-experiments/split... Hydrogen allows you to skip steps in the typical ammonia plant. Synthesized gasoline is just a huge cost increase, almost an order of magnitude larger than that for clean ammonia.
