# Wastewater-Derived Ammonia for a Green Transportation Fuel

Hydrocarbon fuels produce gases such as carbon dioxide from combustion processes used in engines. This gas production has influenced climate change and these fossil fuels do come from a sustainable source. Fuels like ammonia do not contain carbon and thus will not produce carbon dioxide during combustion providing a reduction on the impact to climate change. This work proposes to develop the ability to produce ammonia fuels from wastewater sources. This process will produce a fuel with minimal impact on climate change, while also producing water in a sustainable manner. Combustion studies will analyze the influence of wastewater derived ammonia on the ignition and combustion processes. Impurities from this sustainable source will be analyzed to ascertain how these fuels can be implemented in an engine. Further development of an ammonia laser diagnostic will be used to probe the combustion chemistry during the combustion process that will provide details about how the combustion chemistry is affected by these impurities. Findings from this effort will provide the initial proof of concept to obtain funds from a larger external sponsor.
