Nitrogen-Based Fuels: Renewable Hydrogen Carriers
Ammonia Turbine Power Generation with Reduced NOx
A common concern with ammonia fuel is that NOx emissions will be too high to control. However, in new research from Turkey, USA, and Japan, presented at this year's NH3 Fuel Conference in September 2016, two things became clear. First, NOx emissions can be reduced to less than 10ppm by employing good engineering design and exploiting the chemical properties of ammonia, which plays a dual role as both the fuel and the emissions-cleanup agent. Second, the deployment of ammonia-fueled turbines for power generation is not only feasible, but actively being developed, with demonstration units running today and improved demonstration projects currently in development.

Displacing Diesel Fuel with Carbon-Free Anhydrous Ammonia
The team at the University of Minnesota announced last month the award of funding for a demonstration project entitled "Clean Vehicles Fueled by Hydrogen from Renewable Ammonia." This project builds on years of research and investment in renewable ammonia at University of Minnesota, most visibly the prototype wind-to-ammonia production plant operating since 2014 at West Central Research and Outreach Center. Their focus now, however, is shifting to the use of ammonia as a fuel. "The overall objective of the project is to displace up to 50% of the diesel fuel used in tractors with anhydrous ammonia produced from renewable resources."
