The Singapore government and relevant industry players recently undertook a study to determine the feasibility of integrating sustainable aviation fuels (SAF) with conventional jet fuel for use at Changi Airport. The study, which also identified viable feedstock-technology combinations for the production of sustainable aviation fuels, found that SAF could reduce carbon emissions by up to 80% compared with conventional jet fuel on a lifecycle basis. However, they were expected to cost two to five times more.
To increase its viability, Singapore is looking at methods to increase the uptake and production of these fuels, allowing them to be implemented domestically in Singapore’s available fuel mix and exported internationally. However, the Singapore government noted that developing its supply chain of SAF to improve cost competitiveness and supply was its main priority, as current supply was still limited. Once sufficiently developed, it would be available in Singapore and potentially for the region, benefiting Singapore-based carriers and any other carriers that come into Singapore.
