Ammonia (NH3) is a colorless, gaseous and water-soluble compound used in several sectors, including agriculture, the energy sector, and a variety of industries. For over a century, the main way of producing large quantities of ammonia has been via the Haber-Bosch process, which entails the use of high pressure to produce a chemical reaction that enables the direct synthesis of ammonia from hydrogen and nitrogen.
