The purpose of this test was to assess the performance of the engine technology with 100% SAF compared to Jet A/A1. Ground tests were conducted over several days on an HF120 engine at GE’s Peebles Test Operations using HEFA-SPK*, the most widely available SAF, produced from spent vegetable cooking oil, waste fats and fats. The test results are very favourable, with engine performance equivalent to Jet A fuel during the SAF run.
“As our tests show, the HF120 engine can run on approved SAF today and in the future. Our customers can be confident that the HF120 engine can help them meet their sustainability goals of reducing in-flight CO2 emissions, thanks to the innovative design features of the HF120,” said Melvyn Heard, president of GE Honda.
“We are excited to share one of the steps GE Honda Aero Engines is taking towards carbon neutrality, based on our belief that reducing our impact on the environment is not just an initiative, but a commitment,” said Shinji Tsukiyama, executive vice president of GE Honda. “In addition to the best-in-class fuel efficiency of the HF120, future use of 100% SAF on the HF120 will further contribute to environmental sustainability.”
GE Honda’s parent companies are both part of several international efforts that aim to standardize industry specifications and ensure SAF’s safety.
The HF120 has already proven to be the most fuel efficient engine in its class, representing decades of research and development. Innovative aerodynamic designs, such as unique air-jet fuel nozzles that deliver superior fuel-to-air combustion, minimizing fuel consumption, and laser-drilled combustion chamber holes that allow optimum transfer of compressor energy to the turbine. GE Honda is committed to unlocking new opportunities and going above and beyond in reducing CO2 emissions and is on track to lead the future of sustainable operations for business jets in its class.
