Crack Ammonia into Hydrogen for Alternative Aircraft Fuel

  • Device for cracking ammonia into hydrogen and nitrogen for aircraft fuel
  • Enables the use of ammonia as a carrier of electricity-derived, green hydrogen
  • Suitable alternative aircraft fuel to compete with sustainable aviation fuels (SAF) and hydrogen


The University of Central Florida invention is a device for catalytically cracking ammonia into hydrogen. Ammonia can be a suitable alternative aircraft fuel to compete with sustainable aviation fuels (SAFs) and hydrogen. Compared to hydrogen, ammonia has advantages with respect to volumetric energy density, safety, and the supply chain. The non-coking properties of ammonia make it a suitable heat sink for intercooling compressor air. Instead of burning ammonia directly, the system catalytically cracks it into hydrogen. Performance data of an existing aircraft engine for a modern narrow-body aircraft was adapted to the novel fuel concept and an intercooler was sized based on expected operating conditions on the ground and during flight.

Partnering Opportunity

The research team is looking for partners to develop the technology further for commercialization.


  • Allows for safer fuel storage and transportation
  • Separates hydrogen and nitrogen gases; routes hydrogen to the combustion system and ejects nitrogen into the atmosphere
  • Ammonia can provide cooling for the compressor and for NOx elimination

Potential Applications

  • Chemical companies
  • sCO2 power systems
  • Energy storage
