MIT Uses AI to Challenge a Century-Old Process for Mass Ammonia Production
Ammonia production consumes as much as 2% of the world's energy and generates roughly 1.5% of global greenhouse gas emissions, largely because the industry still relies on a century-old process powered by fossil fuels. Roughly 80% of the 200 million metric tons of ammonia produced globally every year goes into nitrogen fertilizers, with the rest used in plastics, textiles, explosives and other industrial chemicals.

Key Facts
- Fact 1: Ammonia production consumes as much as 2% of the world's energy and generates roughly 1.5% of global greenhouse gas emissions, largely because the industry still relies on a century-old process powered by fossil fuels.
- Fact 2: Roughly 80% of the 200 million metric tons of ammonia produced globally every year goes into nitrogen fertilizers, with the rest used in plastics, textiles, explosives and other industrial chemicals.
- Fact 3: But conventional ammonia production generates hundreds of millions of metric tons of CO2 every year and ranks among the world’s most energy-intensive chemical processes.

Researchers at the Massachusetts Institute of Technology (MIT) have now developed a new method that uses AI and quantum-mechanical calculations to identify the catalyst combinations most likely to cut the energy required to produce ammonia electrochemically. Instead of synthesizing and testing thousands of alloys one by one, the researchers can use AI to predict which combinations are most likely to lower the energy needed to make ammonia. Electrochemical ammonia synthesis has been studied for decades as an alternative to the traditional Haber-Bosch process.
