Ammonia has had a significant global impact since the Haber Bosch (H-B) process was discovered for its synthesis from hydrogen and nitrogen at the beginning of the 20th century. Today, ammonia plays a key role as an essential feedstock of inorganic fertilizers, supporting food production for approximately half of the world's population. Ammonia synthesis is among the largest carbon dioxide-emitting industrial processes and is therefore a prime opportunity for the application of renewable energy.
