Emirates airline made its first demonstration flight with a Boeing 777-300ER, fueling one of its engines with 100% sustainable aviation fuel (SAF). The plane took off from Dubai International Airport and flew over the city’s coast for more than an hour.

For each blend ratio, a series of measurements of the chemical and physical properties of the fuel were made. After extensive laboratory testing and rigorous testing, a blend ratio was arrived at that reflected the qualities of jet fuel.
18 tons of SAF were blended, consisting of HEFA-SPK supplied by Neste (hydroprocessed fatty acids and esters and synthetic paraffinic kerosene) and HDO-SAK from Virent (hydrodeoxygenated synthetic aromatic kerosene). SAF supplied 100% to one GE90 engine, and conventional aviation fuel to the other engine. Currently, the use of SAF is authorized in all aircraft, but only in blends of up to 50% with conventional aviation fuel.
“This flight is a milestone for Emirates and a positive step for our industry as we work collectively to address one of our biggest challenges – reducing our carbon footprint. It has been a long journey to finally see this 100% SAF demo flight take off.” Emirates is the first passenger airline in the world to operate a Boeing 777 with a 100% SAF GE engine,” said Adel Al Redha, Emirates Airline Chief Operating Officer.
