KLM, CFM International and Neste conduct engine test using 100% Sustainable Aviation Fuel (SAF)

KLM has edged nearer to proving the viability of air travel using 100% Sustainable Aviation Fuel (SAF) following a test at its Engineering & Maintenance’s test cell at Schiphol-East.

KLM joined forces with its partners, engine manufacturer CFM International and fuel producer Neste, to conduct the test on an aircraft engine using HEFA-SPK – 100% SAF made from used cooking oil.

The first round of the test was powered using standard fuel and the second using HEFA-SPK. Extensive inspections and checks were carried out on the engine during and after the test run.

Along with other data, the engine’s pressure and temperature were measured throughout to show how efficiently the engine handled the fuel and its effects on various components.

The test data will be used to draft fuel specifications for the future and will contribute to making the airline industry more sustainable.

SAF emits less CO2 over its entire lifecycle than regular fuel. It is currently approved for use in all aircraft, but only in blends of up to 50% with conventional jet fuel.

The use of 100% SAF in aviation has not yet been approved and requires certain specifications, which can only be determined based on extensive research and data. Engine tests like this contribute to this research.
