by Juan Pedro Thomas (Biofuels Digest) GE Aerospace announced on its social media channels that the General Electric GEnx engine had recently completed ground testing on 100% sustainable aviation fuel. The company noted that the SAF testing was carried out in collaboration with NASA. The engine is attached to a Boeing 787-10 Dreamliner jet. “These tests help increase understanding of SAF and how it might positively impact air quality compared to conventional jet fuel,” GE Aerospace said.

GE Aerospace Runs A Boeing 787-10 Engine On 100% SAF — The race is on with Rolls-Royce for who will get a Dreamliner engine to 100% SAF first. (Simple Flying)

Excerpt from Simple Flying: Meanwhile, the engine is not the first that General Electric has run on 100% sustainable fuel. In May 2022, GE ran the Passport business jet engine, which entered service in 2018, on 100% SAF during a series of ground tests at its Peebles Test Operations in southern Ohio.

In 2021, the CFM International (a joint partnership between GE Aerospace and Safran) LEAP 1B engine powered the first passenger flight with 100% SAF in one engine when United Airlines operated a Boeing 737 MAX from Chicago’s O’Hare to Washington’s Reagan National Airport with 115 people on board on December 1.

The Boeing ecoDemonstrator Alaska Airlines 737-MAX 9 also tested 100% SAF in its LEAP 1B together with NASA in October of the same year, measuring engine particle and trace gas emissions over different thrust settings and comparing different percentage blends of SAF vs. Jet A fuel.

…

Regulators will need to be satisfied that a pure sustainable aviation fuel blend will be entirely failsafe before increasing from the current 50% allowance. Results of all tests thus far are promising, and we are bound to see much more 100% SAF testing – as well as testing with different types of lower-carbon fuels – as the year progresses. READ MORE
