Currently, only a 50% blend of conventional and sustainable aviation fuel has been approved for use
Emirates has signed an MoU with GE Aviation 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, the 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 the adoption of 100% SAF, which does not require blending with conventional jet fuel.
Planned for the end of next year, the 100% SAF test flight is expected to demonstrate how wide-body commercial aircraft using jet fuel made from alternative sources can lower lifecycle CO2 emissions compared to petroleum-based fuels with no operational issues.
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. By starting with alternative feedstocks instead of fossil fuels, CO2 emissions can be reduced during production.
Emirates Airline COO Adel Al Redha: “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 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.”
