Ammonia is produced at scale by the Haber-Bosch process, N2 + 3H2 => 2NH3. Most H2 is currently produced by steam reformation of natural gas, CH4 + 2H2O => CO2

Ammonia is produced at scale by the Haber-Bosch process, N2 + 3H2 => 2NH3. Most H2 is currently produced by steam reformation of natural gas, CH4 + 2H2O => CO2 + 4H2. It's not really feasible to turn ammonium nitrate back to natural gas, moreso GP was insinuating it's a way to export (a proxy for) natural gas, eg to bypass sanctions.
