Typically the natural gas is the source of the hydrogen. Usually natural gas is burned to form steam to split more natural gas (CH4) into carbon and hydrogen. That’s traditionally cheaper than electrolysis.
Free has a habit of changing the economics. This is good news, decoupling ammonia from natural gas would make agriculture more resilient to Middle East disruptions.

TFA literally states "Wind energy powers the electrolysers that supply hydrogen to a Haber Bosch plant." First paragraph.
Unless your electricity is 'free', presumably?

It’s mot powered with fossil fuels. It uses fossil fuels as an ingredient.
No it doesn't. It electrolyses water and combines the resulting hydrogen with nitrogen from the air.
Wrong. Natural gas is the most common catalyst, but plenty of plants use oil, coal, and other hydrocarbons.
