20-month Sustainable Aviation Fuel (SAF) Pilot Completed at Changi

  • 05 Nov 2023

In the leading efforts to create a long-term secured Sustainable Aviation Fuel (SAF) supply ecosystem and develop a Sustainable Air Hub in Singapore, the Civil Aviation Authority of Singapore (CAAS), in partnership with Temasek, GenZero, and Singapore Airlines (SIA), announced the completion of the 20-month Sustainable Aviation Fuel (SAF) pilot in Changi that commenced in February 2022.

After the pilot, CAAS mentioned on 2 November that although Singapore is operationally ready to supply SAF, more support is still required for adoption.

Three aspects that was derived from the 20-month SAF Pilot

1) Operational Readiness – From the procurement and the blending of SAF with conventional jet fuel to the safety certification and delivery of the SAF to the airport, the pilot affirmed that SAF can be safely deployed and uplifted onto flights without any modification to the existing airport infrastructure.

2) Generation of SAF credits – Generating SAF credits for sale helps airlines and air cargo companies reduce cost burden on the higher-costing SAF while playing a part in decarbonisation. During the pilot, SIA purchased 1,000 tonnes of neat SAF that generated 1,000 SAF credits, which corresponds to about 2,500 tonnes of CO2 reductions. The successful and transparent transactions in SAF credits from the pilot laid the foundation for a reliable global SAF credit marketplace for the future.

3) Market Readiness – Out of the 1,000 credits generated, about two-thirds were sold during the pilot. While this validated the existing market demand for SAF credits, it also indicated that for a large-scale SAF adoption, more support will be required through education, outreach, and corporate and government policy.

As countries and aviation companies all strive toward the net-zero carbon emission goal in 2050, SAF would be a key factor in contributing to Singapore aviation’s efforts in decarbonisation.

Mr Han Kok Juan, Director-General of CAAS also highlighted the importance of SAF for the Singapore aviation industry. Moving forward, he added that “CAAS is developing a structural offtake mechanism to support SAF adoption. This will take into account developments elsewhere in the world, including discussions at the upcoming third International Civil Aviation Organization Conference on Aviation and Alternative Fuels.”
