NASA-Backed Program To Trial Ammonia As Alternative Jet Engine Fuel

While biofuels, Power-to-Liquids, and hydrogen have long been touted as the alternative fuels of the future, researchers are becoming increasingly convinced that ammonia, a compound of nitrogen and hydrogen, could also be part of the solution for net-zero emission flights. In a five-year project backed by the US National Aeronautics and Space Administration (NASA), the University of Central Florida (UCF) will analyze, test, and qualify ammonia as an option for powering aircraft jet engines sustainably.

The project is funded by a NASA University Leadership Initiative five-year grant to accelerate aviation sustainability. Researchers will use simulation technology developed by an engineering software company called Ansys. This will allow them to simulate complex chemical reaction systems surrounding ammonia, including vaporization of liquid ammonia inside heat exchange tubes, heat transfer, and the combustion of ammonia and hydrogen in the air.
