Tackling sustainable fertilizer production with an alternative electrolyte

Read the full story in Chemical & Engineering News.

Ammonia is a vital ingredient in the fertilizers that sustain global agriculture, but it comes with a huge environmental cost. The Haber-Bosch process, which combines nitrogen and hydrogen to make ammonia, consumes about 2% of the world’s energy supply, and its hydrogen feedstock is made by steam reforming methane at high temperature and pressure, producing significant CO2 emissions. An electrochemical system that relies on an unusual electrolyte could now point the way to a more sustainable form of ammonia production (ACS Energy Lett. 2018, DOI: 10.1021/acsenergylett.8b00487).
