Low-Carbon Intensity Ammonia for Sustainable Agriculture

What is it about?

Ammonia, a key ingredient in fertilizers, is a major contributor to carbon emissions, especially in agriculture. Our study explores how using low-carbon ammonia could significantly reduce the environmental impact of corn production in the U.S. Corn Belt, a key region for biofuel crops. Replacing conventional ammonia with green ammonia, produced from renewable energy, could cut carbon emissions by 33%, while using blue ammonia, which incorporates carbon capture and storage, could reduce emissions by 26%. Despite these environmental benefits, our analysis shows that low-carbon ammonia is still more expensive than conventional ammonia. Even with government incentives, such as tax credits, green ammonia costs over twice as much as conventional ammonia, while blue ammonia remains slightly more costly. To make low-carbon ammonia a viable option, stronger carbon pricing policies, like a carbon tax, will be essential to bridge the cost gap. This research emphasizes the potential for low-carbon ammonia to make agriculture more sustainable while highlighting the economic challenges that need to be addressed.

Why is it important?

What makes this research unique and timely is its focus on ammonia's critical role in agricultural emissions and its connection to biofuel sustainability—a topic of growing global concern as countries strive to meet climate goals. With increasing attention to decarbonizing agriculture and advancing cleaner technologies, our findings provide a much-needed analysis of both the environmental potential and economic challenges of transitioning to low-carbon fertilizers.
