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 …
