Feedstock industry

Hydrogen’s largest use historically, by far, has been as a feedstock or chemical agent in the refining, petrochemical, chemical, fertilizer, steel, and food industries. Hydrogen is vital to the major reactions of hydrodesulfurization, hydrocracking, hydrodealkylation, hydrogenation and reduction reactions that upgrade/clean our fossil fuels, saturate fats and oils, and produce building block chemicals (like ammonia and methanol).
