Chemical researchers develop “green” ammonia Ammonia has sustained humanity since the early 20th century, but its production leaves a huge carbon footprint. Now researchers have found a way to make it 100 per cent renewable.
The researchers used a bubble column to break down nitrogen, creating reactive water which was then processed in a second electrochemistry reactor. Credit: Professor Patrick ‘PJ’ Cullen.
Ammonia is one of the world’s most important chemicals that supports global food supply, used primarily in the production of fertilizer, enabling better agricultural productivity.
However, the production of ammonia is incredibly energy-intensive, accounting for roughly two percent of global energy consumption. It is also highly eco-destructive, comprising 1.4 percent of total global CO2 emissions.
