Honeywell Tests Using SAF in its APUs and Propulsion Engines

Honeywell recently received its first delivery of sustainable aviation fuel at its Phoenix Engines campus. The fuel will support development and production testing of auxiliary power units (APUs) and propulsion engines at the site, along with testing of fielded units from Honeywell’s repair and overhaul facility. Developed by World Energy in California using Honeywell’s UOP Ecofining technology and distributed by World Fuel Services, the sustainable aviation fuel (SAF) is produced by converting readily available renewable materials such as hydrotreated esters and fatty acids (HEFA). SAF can be combined with conventional jet fuel to power aircraft in blends of up to 50 percent with petroleum-based jet fuel. Blended SAF requires no changes to engine or aircraft fuel systems or fuel infrastructure. Honeywell also has plans to test other SAF blends and to run engines and APUs on 100 percent SAF in the future.”At Honeywell, we see SAF as a logical path to decarbonize the aviation industry and we consider our facilities as laboratories for sustainable innovation,” said Dave Marinick, president of engines and power systems, Honeywell Aerospace.
