Origin German Chemist Fritz Haber found this process at the beginning of the 20 th century, right before WWI. Before that Germany imported nitrates from South America, but the demand of Nitrates increased before the war.
Origin During WWI, Allies blocked all the trade routes of Nitrates to Germany, but Germany was still able to produce fertilizers and explosives because of the Haber process.

Obtain hydrogen Most hydrogen now is produced from “Steam- Methane Reforming”, methane is reacted with high-temperature steam(under high pressure) to form carbon monoxide and hydrogen. CH 4 + H 2 O (+heat) → CO + 3H 2
Obtain hydrogen After that the carbon monoxide is combined with steam (+catalyst) and carbon dioxide and hydrogen. CO + H 2 O → CO 2 + H 2 (+heat)
Obtaining hydrogen Electrolysis is also used to obtain hydrogen, but greenhouse gas is produced from burning fossil fuels to make electricity, so this method is less common compared to “Steam-Methane Reforming”.
Obtaining Nitrogen Nitrogen is obtained from the air. (of course) Air is cooled to ≈-200 o C, then fractionally distilled.
