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.
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%. One of GE’s fuel experts chairs an international task force to develop standardised industry specifications supporting adoption of 100% SAF, which does not require blending with conventional jet fuel.
A milestone collaboration for both Emirates and GE Aviation, 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.
The demonstration flight also supports both companies’ broader efforts to reduce CO2 emissions as the industry looks to scale up its use of SAF.
Emirates will work closely with regulators to secure approvals for experimental type certification, and will also coordinate with airframe, Auxiliary Power Unit (APU) and Original Equipment Manufacturers (OEMs) on pre- and post-flight requirements, in addition to closely working with SAF suppliers on procurement and delivery logistics.
Adel Al Redha, chief operating officer, Emirates Airline, said: “Emirates is committed to supporting initiatives that help minimise its CO2 emissions, and we’ve already made great strides in fuel efficiency and conservation as well as operational advancements across different areas of our business. Our agreement with GE Aviation will support progress on the industry’s collective commitment to net zero emissions, and we look forward to continuing this close collaboration. 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.”
In addition to customer support, GE Aviation will complete necessary technical reviews to confirm the engines will meet performance specifications and provide any pre- and post-flight directions as needed.
“GE Aviation is committed to pursuing efforts to reduce CO2 emissions from commercial aviation, including developing technologies for the fleet in service and the future of flight. This collaboration with Emirates is key to our efforts to standardise 100% SAF globally, which could provide a significant opportunity to expand the impact of SAF on aviation’s carbon reduction efforts,” said John S. Slattery, president and CEO of GE Aviation.
