SAF: Hydrogen out in Front?

3 min readNov 29, 2022


In this newsletter, we have talked extensively about Sustainable Aviation Fuels (SAFs), and their potential for the aviation industry. We have shared thoughts from both sides of the aisle with regard to whether SAFs will be a net benefit for the industry or a net disbenefit. In this week’s On Aviation™ digest, we share some new developments in hydrogen-powered engine development, one of the many potential sources for SAFs.

World’s 1st hydrogen-powered jet engine seeks turning point for aviation industry

Aerospace manufacturer Rolls-Royce said Monday it had successfully tested and run the world’s first hydrogen-powered aircraft engine. The first-of-its-kind engine could prove a significant milestone in the development of eco-friendly fuel for the aviation industry. In a press release, Rolls-Royce said it had tested an early concept engine using hydrogen from wind and tidal power. The test was performed in collaboration with British low-cost air carrier easyJet, and officials said the hydrogen engine was a “key proof point” in the decarbonization strategies of both companies.

Rolls-Royce tests hydrogen-fueled aircraft engine in aviation world first

British engineer Rolls-Royce has successfully used hydrogen instead of conventional jet fuel to power a modern aircraft engine in a world first for the aviation industry, according to the company.The ground test, which took place at a government test facility at Boscombe Down, used green hydrogen generated by wind and tidal power from the Orkney Islands in Scotland. Rolls-Royce used a converted AE 2100-A turboprop engine that powers civil and military aircraft to conduct the test in partnership with easyJet.

UK bets on green hydrogen for zero-carbon commercial aviation

As much as we need to cut aviation’s emissions, batteries aren’t going to do the trick. To replace turbine-driven airliners with similarly-sized electric aircraft will require a monumental leap in battery technology — and we’re simply not there yet. According to studies by the UK’s Aerospace Technology Institute (ATI), aviation can achieve the net-zero 2050 target through the development of both sustainable aviation fuel (SAF) and green liquid hydrogen technologies.

Rolls-Royce and EasyJet Set New Aviation World First With Successful Hydrogen Engine Run

Rolls-Royce and easyJet today (November 28, 2022) confirmed they have set a new aviation milestone with the world’s first run of a modern aero engine on hydrogen. The ground test was conducted on an early concept demonstrator using green hydrogen created by wind and tidal power. It marks a major step towards proving that hydrogen could be a zero carbon aviation fuel of the future and is a key proof point in the decarbonization strategies of both Rolls-Royce and easyJet.
