UW-Madison researchers have developed an improved method of synthesizing ammonia from hydrogen sulfide and lithium nitrate. This process, currently embodied in a continuous cycle, leverages hydrogen sulfide reactant cycling via an elemental sulfur intermediate in conjunction with a water-containing or water and carbon-containing feedstock. Ultimately, this new process could be used to produce ammonia at scale while decreasing the amount of external energy required, particularly when compared to the Haber Bosch process. 

• Potential energy and cost improvements to Haber Bosch
• Reduced carbon footprint for a more green ammonia production route
