Dubai-based Emirates Airline has efficiently accomplished the bottom engine testing for one in all its GE90 engines on a Boeing 777-300ER utilizing 100 per cent Sustainable Aviation Gas (SAF), which is claimed to cut back carbon emissions over the gasoline’s life cycle by as much as 80 p.c
The goal of the check was to examine the potential of the GE90 engine to run on the specifically blended SAF with out affecting its efficiency, requiring no modifications to the plane techniques, or particular upkeep procedures on the Boeing 777-300ER or GE90 engine to function.
The bottom check outcomes will now pave the best way for the airline’s first experimental check flight utilizing 100 per cent SAF in a single engine, which is due for take-off this week.

The testing actions concerned working one engine on 100 per cent SAF and the opposite on typical jet gasoline to raised analyze the gasoline system’s habits and efficiency below every gasoline sort, examine particular outputs of every engine and guarantee seamless operation of the plane’s engine and airframe gasoline techniques throughout the deliberate check flight.
In the course of the floor testing held on the Emirates Engineering Middle in Dubai, the plane first went by its normal pre-inspection actions. After that, the stationary working testing started by first working the Honeywell 331-500 auxiliary energy unit (APU) on 100 per cent SAF.
The APU was then put below full load with SAF to start out the engines. The left engine was exercised by its full energy vary, utilizing the identical settings that shall be used for the experimental flight. This included idle, ‘take-off’ and ‘climb settings’ at full flight profile durations, working at most velocity and depth. Engines had been then run at ‘cruise’ settings for quarter-hour. After the simulation ended, the engines had been cooled down.
Fuels had been remoted in separate gasoline tanks to keep up the segregation of check fuels. Upon completion of the bottom check, engine knowledge was downloaded for assessment, comparability, and evaluation.
Now we have accomplished floor engine testing utilizing 100% Sustainable Aviation Gas (SAF). Keep tuned for our experimental check flight that is taking place later this week. 👋✈️ https://t.co/FngmqsbUtr pic.twitter.com/6ZoEr27RG5

Emirates has been working with its companions GE Aerospace, Boeing, Honeywell, Neste and Virent, a subsidiary of Marathon Petroleum Corp all through 2022 on SAF gasoline mix testing. The companions have developed a mix with the identical qualities and efficiency traits of typical jet gasoline and have collaborated on the technical evaluation and operational necessities surrounding floor testing and experimental flight actions.
The outcomes of this initiative will present extra knowledge and analysis round artificial gasoline mix parts and biofuels, supporting standardization and future approval of 100 per cent drop-in SAF.
Following the profitable trial on one engine, the airline will proceed to develop these initiatives with the engine airframe producers in addition to SAF suppliers with the purpose of certifying these blends for business use. At present, SAF is authorised to be used in blends of as much as 50 per cent with typical jet gasoline.
The airline has been a supporter of business and authorities efforts to encourage the event of the SAF business, and recurrently participates in initiatives to contribute to SAF deployment. Its first flight powered by SAF blended with jet gasoline was in 2017, working from Chicago O’Hare airport on a Boeing 777. It acquired its first A380 powered by SAF in December 2020, and uplifted 32 tons of SAF for its flights from Stockholm earlier that 12 months, with the assist of Swedavia’s Biofuel Incentive Programme. Flights from Oslo have additionally begun working on SAF.
On the Dubai Airshow 2021, Emirates, GE Aerospace and Boeing signed a Memorandum of Understanding (MoU) to develop a program for conducting a check flight utilizing 100 per cent SAF on an Emirates 777-300ER powered by GE90 engines.

Emirates can also be on the Steering Committee of the World Financial Discussion board’s (WEF) Clear Skies for Tomorrow initiative, which seeks to advertise SAF deployment worldwide. The airline has additionally contributed to the UAE authorities’s work on a SAF roadmap and the WEF-supported Energy-to-Liquids Roadmap for the UAE.
UAE is selling the usage of SAF
In different information, Masdar, ADNOC, bp, Tadweer (Abu Dhabi Waste Administration Firm) and Etihad Airways are set to hold out a joint feasibility examine exploring the manufacturing of sustainable aviation gasoline (SAF) and different merchandise, resembling renewable diesel and naphtha , utilizing municipal strong waste (MSW) and renewable hydrogen.
The announcement was made on the Abu Dhabi Sustainability Week, which concluded on January 19.
