A major step towards 'greener ammonia' and a more 'greener fertilizer

Jan 24, 2023

A major step towards 'greener ammonia' and a more
'greener fertilizerAmmonia production is the most energy-intensive
industrial process. The Haber-Bosch method for making
ammonia is the most energy-intensive. It uses approximately 1% of all fossil
fuels worldwide and emits 1% of all carbon dioxide, which makes it a
significant contributor to climate change.Berkeley University chemists are now making a significant
step towards making ammonia production more sustainable. They have developed a
"greener ammonia" for fertilizer.The Haber-Bosch process requires large pressure and
temperature swings to separate the ammonia and reactants. This is a major
obstacle in making ammonia with lower energy input. The reaction occurs between 300 and 500 degrees
Celsius. However, ammonia can be removed by cooling the gas down to
approximately 20 Celcius. At this point, the gaseous ammonia becomes a...
