Why firms are racing to produce green ammonia - BBC News

BBC  New for our State broadcaster

Ammonia, or NH3, is nothing more than nitrogen and hydrogen, both highly abundant elements. Earth's atmosphere is mostly nitrogen, and water is full of hydrogen. Starfire Energy uses electrolysers to split hydrogen from water and then feed it into a reactor along with nitrogen to make their ammonia.

The ingredients flow through a honeycomb structure laced with a catalyst - similar to the catalytic converter in your car's exhaust. This device encourages nitrogen to bond with hydrogen, and liquid ammonia is collected at the end of the process.
