Dubai: Emirates and GE Aviation have signed a Memorandum of Understanding (MoU) to develop a programme that will see an Emirates Boeing 777-300ER, powered by GE90 engines, conduct a test flight using 100% Sustainable Aviation Fuel (SAF) by the end of 2022. Emirates’ first flight powered by SAF was in 2017, operating from the Chicago O’Hare airport.
Currently, SAF approved for use is a blend of petroleum-based Jet A or Jet A-1 fuel and a SAF component with a maximum blend limit of 50%. 100% SAF does not require blending with conventional jet fuel.
The 100% SAF test flight is expected to demonstrate how widebody commercial aircraft using jet fuel made from alternative sources can lower lifecycle CO2 emissions compared to petroleum-based fuels with no operational issues.
Adel Al Redha, Chief Operating Officer, Emirates Airline, said: “Our partnership with GE Aviation to prepare for the test flight will be an important step towards securing certification of flights that are powered by 100% SAF.”
The airline is also a member of the Clean Skies for Tomorrow coalition, established by the World Economic Forum, which is supporting a transition to SAF as part of a pathway towards carbon-neutral flying.
All GE Aviation engines can operate with approved SAF, which is made from plant oils, algae, greases, fats, waste streams, alcohols, sugars, captured CO2, and other alternative feedstock sources.
