Manufacturer Honeywell to test SAF in its APUs

APU and engine manufacturer Honeywell has decided to start using sustainable aviation fuel (SAF) for the development and production testing of its aircraft auxiliary power units and propulsion engines. Honeywell has plans to test SAF blends and to run engines and APUs on 100% SAF in the future.

Auxiliary Power Units (APUs) are small, self-contained systems installed in aircraft to provide power for various functions such as air conditioning, electrical power, and starting the main engines. They enable the main engines to be shut down during ground operations, reducing fuel consumption and emissions, while still providing necessary power. APUs also provide a backup power source in case of engine failure.

In a statement on PRNewsWire, Dave Marinick, president of Engines and Power Systems, Honeywell Aerospace, said: "Honeywell has a wide variety of ready-now solutions to help create a more sustainable future for the aviation sector, and we are proud to make this progress on our sustainability commitments in our propulsion and power systems portfolio. Running our engines and APUs on SAF is a further demonstration of our commitment to our customers to do our part to reduce our carbon footprint."

Honeywell is committed to achieving carbon neutrality in its operations and facilities by 2035. Using SAF to power its APUs and engines will bring that goal closer.
