A major ingredient in the production of fertilizers for the world’s food production, ammonia also contributes to greenhouse gas emissions and
Ever wondered about the carbon impact of growing your dinner? Scientists have just come up with a new way to calculate part of it.
The use of ammonia as a fertilizer creates greenhouse gas emissions, recently quantified by scientists at Argonne. Image courtesy of Cynthia Shahan,Ammonia is principally made by reforming natural gas, a process that contributes to the atmospheric emissions of both carbon dioxide and methane. The ultimate goal is to use renewable or nuclear energy and clean hydrogen to produce it instead,” said Argonne senior scientist Amgad Elgowainy.
The first way avoids some of the carbon release by capturing a certain percent of the carbon produced and then storing it in geologic formations. This technology pathway can be implemented at relatively low cost, as the total cost to produce the ammonia increases by only about 20%.
