Wastewater-Derived Ammonia For A Green Transportation Fuel, Joseph Kalman, Maryam Haddad
Wastewater-Derived Ammonia For A Green Transportation Fuel, Joseph Kalman, Maryam Haddad
Mineta Transportation Institute
The energy-water nexus (i.e., availability of potable water and clean energy) is among the most important problems currently facing society. Ammonia is a carbon-free fuel that has the potential to reduce the carbon footprint in combustion related vehicles. However, ammonia production processes typically have their own carbon footprint and do not necessarily come from sustainable sources. This research examines wastewater filtration processes to harvest ammonia for transportation processes. The research team studied mock wastewater solutions and was able to achieve ammonia concentrations above 80%(nanofiltration) and 90% (reverse osmosis). The research team also investigated the influence of transmembrane pressure and flow …
Ammonia Cycling And Emerging Particulate Matter Pollutants Under Arable Land-Use Management: A Modelling Approach, Vivien Pohl
Ammonia Cycling And Emerging Particulate Matter Pollutants Under Arable Land-Use Management: A Modelling Approach, Vivien Pohl
Doctoral
Air quality monitoring in Ireland is under the jurisdiction of the Environmental Protection Agency in compliance with the Gothenburg Protocol, EU/national legislation, and the National Clean Air Strategy. Particulate Matter (PM) has been acknowledged as a key atmospheric pollutant, with serious public health impacts and no safe threshold of exposure in place to-date. Ammonia (NH3) emissions are linked to the secondary production of PM through atmospheric reactions occurring with acidic atmospheric components such as sulfuric acid, nitric acid, and hydrochloric acid. These reactions result in the formation of ammonium sulfate, ammonium nitrate and ammonium chloride, among others. More than 95% …
