Ammonia for plane fuel: UCF to lead $10m NASA project to develop zero-carbon jet engines

The University of Central Florida (UCF) is developing new technology that is expected to make airplane engines emission-free, an effort that could potentially revolutionize the aviation industry.

UCF put together a team of experts and stakeholders to evaluate their innovation, which aims to not only make aviation fuel green, but also create engines and fueling systems that easily integrate into current airport infrastructure, thus saving airports and aircraft manufacturers millions of dollars as they look to retrofit.

"We don't want to create something that will be too cumbersome and expensive to implement," said lead investigator and UCF Engineering Professor Jay Kapat. "If we want people to adopt this green tech, it needs to be scalable. To adopt hydrogen, for example, we can't expect every airport to set up large cryogenic liquid hydrogen systems like Kennedy Space Center. That's unreasonable."

With this practical approach, Kapat put together a team of experts from UCF, Georgia Tech, and Purdue and industry experts from Boeing, General Electric, ANSYS, Southwest Research Institute, and the Greater Orlando Aviation Authority. The team landed a $10 million five-year NASA University Leadership Initiative grant to get the ball rolling.

"We have a good concept," Kapat said, "and by having our partners in industry, we know we'll fine-tune and be ready for technology transition, so we can provide a greener future for our children."

The technology
Kapat and several of his UCF colleagues in engineering and the Florida Space Institute propose using liquid ammonia (NH3) as the fuel for aircraft which, upon combustion, will produce harmless emissions that are green while still providing enough power to keep the aircraft aloft. At high altitudes, ammonia is naturally liquid, thereby limiting the need for special handling. Airports and airplanes are expected to store the ammonia in fuel tanks. Ammonia is commonly used as a fertilizer and, when mixed with water, in some household cleaners.

Ammonia will be the hydrogen carrier, which will be catalytically "cracked" to release nitrogen and hydrogen. The hydrogen will be burned in the onboard combustors (inside the engine) to provide the power. Airports and aircraft are expected to store the NH3 in fuel tanks. Excess NH3 will then be used to catalytically reduce any NOx left in the exhaust, converting it to nitrogen and water.

When the hydrogen is released, there will be an added bonus, Kapat explained. The conversion process also provides cooling, which can be used to keep engines from overheating and burning out. The impact may be better engine performance and efficiency. Engine exhaust heat is then converted back to electricity for onboard use, thus reducing power draw from the core engines.

The team also is developing new components for jet engines to be used in conjunction with the new fuel. The team is using the 737-8 class plane for a baseline, because it represents nearly a quarter of all commercial aircraft, according to Boeing.

The team
Catalyst development and improvement of known catalysis pathways are key to the UCF effort and will be undertaken in Professor Richard Blair's laboratory at the Florida Space Institute. Engineering Professor Subith Vasu will lead the efforts to design tools, computer models, and combustion testing from his lab. Professor Kapat will lead a team that will conduct thermal management and system integration at UCF's Center for Advanced Turbomachinery and Energy Research (CATER), which he leads. UCF Chemical Safety and Security Coordinator Sandra Hick will oversee safety and occupational health issues that are central to any use of ammonia and hydrogen.

Georgia Tech will provide its aviation simulation expertise, and Purdue is providing some of its unique labs and expertise in combustion and aerodynamics.

Boeing is providing the integration know-how to the aircraft, and GE is contributing its knowledge of jet engines. Other industry partners are advising on large-scale simulation, the feasibility of the technology in the real world, and providing a pathway for technology transition. Student training and workforce development are also key aspects of the overall project. Several UCF students working under faculty in the various labs will contribute to the research.
