The fertilizer industry is a large consumer of energy and a major contributor to global greenhouse gas (GHG) emissions. Global ammonia production at 235 million metric tons represents the highest production volume for any chemical, the highest energy consumption (30-60 gigajoules per metric ton), and one of the highest GHG emissions (530 million metric tons CO2-equivalent). About 85-88% of ammonia is used in fertilizer manufacturing. While some ammonia is applied on its own as a fertilizer, it is most commonly converted into other nitrogenous products, such as urea and nitrates. The global demand of nitrogen fertilizers is more than 105 million metric tons. Hence, decarbonization of nitrogenous fertilizes will lead to a significant reduction in GHG emissions and carbon footprint. However, nitrogenous fertilizer consumption, with regard to transportation and application, also contributes to GHG emissions. This presentation will highlight the impact of decarbonization on both the production and application of nitrogenous fertilizers. Next-generation nitrogenous fertilizers and alternatives to the Haber-Bosch process will also be discussed.
