Stanford Woods Institute – Making Agriculture More Sustainable


Fall 2020


Project Description

Fertilizer manufacturing has caused global food production to grow exponentially in the past 100 years. However, the process used to manufacture ammonia, a main ingredient in fertilizers, consumes 2 percent of the world’s natural gas and energy, and emits 300 million metric tons of carbon dioxide every year. This project aims to develop a more sustainable approach that is also safer and more affordable.

One of nature’s way of fixating nitrogen is through hot lightning discharges, which dissociate nitrogen and reacts it with oxygen and water vapor. We have developed a novel cold discharge plasma whereby nitrogen is fixated directly in liquid water. This process would be powered by electricity without greenhouse gas release, requiring no natural gas to drive it. The approach has the potential, through use of renewable energy, to eliminate the carbon footprint that has plagued fertilizer production for over a century.
