Gas is needed for fertilizer production because it's one of the input resources - Haber-Bosch capture of ammonia (nitrogen) requires a source of hydrogen and that's usually natural gas since it's rich in hydrogen. As such, lumping in the gas that's used for fertilizer production in with gas used for energy production makes limited sense - it's not fungible and can't just replaced with nuclear (or any other) energy. In the future, it would be possible to use hydrogen generated via hydrolysis, but we're pretty far off doing that on industrial scale.

Relatedly, Russia is a top exporter of fertilizers: https://thehill.com/policy/3513855-why-the-fertilizer-market-could-be-russias-hidden-leverage https://thehill.com/policy/3513855-why-the-fertilizer-market... Interestingly, while over the past 10-15 years the U.S. condemned Germany for importing natural gas from Russia, the U.S. was methodically displacing some of its domestic fertilizer production with imports, a substantial fraction coming from Russia and Belarus--in particular, 12% of U.S. potash consumption comes from Russia, and 93% imported overall.

It seems small but it turned out to be a significant direct short-term lever, and presumably a much bigger lever with many other countries; and that's not even considering indirect leverage from Russia's ability to manipulate global market prices and thus U.S. domestic prices. Perhaps the only thing that hits harder than an increase in energy prices is an increase in food prices. (OTOH, for all I know the USDA, etc, may have actually been diligently working to minimize foreign dependence without being too disruptive--politically or economically--and the current percentages and source country distributions were the best they could accomplish.)

  > 12% of U.S. potash consumption comes from Russia, and 93% imported overall Sounds like the Canadians wanted to charge too much and US finally gave in and sourced an intercontinental supply. I don't think USA is at risk of losing a secure potash supply. Rail transport from Saskatchewan is too cheap into agri America.

There are hydrogen and methane generation processes that also do some small carbon capture, to manufacture ammonia ultimately. The problem is that they require too much heat and electricity and currently are not yet viable. They would be viable in a slightly oversized grid with at least 75% renewables.
