About 50% of the world's food production relies on ammonia fertilizer, an important source of nitrogen that is essential for plant growth. In some fields, it is not uncommon to see 90 kg (200 pounds) of ammonia per acre for each growing season.

Scientists at Australia's Monash University claim to have made a critical breakthrough in green ammonia production that could displace the extremely dirty Haber-Bosch process, with the potential to eliminate nearly two percent of global greenhouse emissions. Ammonia is one of the most heavily-produced industrial chemicals in the world, and absolutely vital to modern society.
