    Natural gas is used to produce hydrogen, which is then used in the Haber-Bosch process to produce ammonia from nitrogen in the atmosphere. Only about 6% of natural gas is used to produce hydrogen, so even if the price were to rise substantially, we could divert natural gas from other uses and have plenty for making ammonia. We also have other ways of producing hydrogen, it’s just that natural gas is more established.

    PEM electrolyzers paired with cheap solar in countries with high insolation can now produce hydrogen for less than the cost of natural gas, but we’re only recently starting to see the construction of the large-scale green ammonia plants needed to accomplish this. Egypt is currently constructing a 100-MW green ammonia plant powered by solar energy. Even if you didn’t have enough PEM eletrolyzers you could still just pass current through some salt water and produce hydrogen, albeit much less efficiently.

    It’s not going to be a catastrophic issue.

      Fun fact: Fritz Haber, the German guy that invented the Haber-Bosch process is the same Fritz Haber that developed a way to use the chlorine gas in chemical warfare. He was personally overseeing its effect in the battle of Ypres.

        Clara Immerwahr, who was married to Fritz Haber and was a successful chemist in her own right, spoke out against his research as a “perversion of the ideals of science” and “a sign of barbarity, corrupting the very discipline which ought to bring new insights into life.” She ended her own life the day before he traveled to the eastern front to oversee the use of chlorine gas against Russian troops.

      Farmers almost uniformly over-apply N fertilizer. Having it be more expensive and forcing them to look into more efficient ways of applying fertilizer and managing nutrients is not a bad thing.

          Farmers are price-takers not price-makers. The prices they receive are driven by speculation on the commodities markets (even for crops not traded on the market).

          Since they can’t control the price they receive for their crop, they are very sensitive to any change in the cost of inputs. Determining how much to spent on inputs is the part of their profitablity they can control. So widespread behavioral change is usually pretty close to immediate.

      We can’t do any of those in a scale large enough to replace the destruction and have it online for the next planting season on the North Hemisphere. Or the next one on the South Hemisphere either, btw. Or the following ones for each.

      It might not be a massive scientific issue but I bet prices will still rise and the news will be fearmongering causing pricing to go up and never come back down. It’s a capitalism issue and corruption and greed.
