Toward sustainable ammonia production
Toward sustainable ammonia production

Ammonia, with its unmistakable urinous odour, is a critical ingredient in agricultural fertilisers. With more than 145 million tonnes manufactured annually, only sulfuric acid outranks it as the world's most produced chemicals. Manufacturing this simple molecule, made from just four atoms - one nitrogen and three hydrogen - is, however, surprisingly difficult and one of the most energy-intensive manufacturing processes on the planet, consuming 3 to 5 percent of the world's annual natural gas production.
