Singapore government agencies are reviewing the findings of a study conducted on the operational and commercial viability of using sustainable aviation fuels (SAF) at Changi Airport.
SAF can reduce carbon emissions by up to 80%, compared with conventional jet fuel on a lifecycle basis, but it is two to five times more expensive, Transport Minister S Iswaran said.
The study, conducted by the Singapore Government and industry players, has presented options to integrate SAF with traditional jet fuel at Changi Airport. The study also identified viable feedstock-technology combinations for the production of sustainable aviation fuels in Singapore.
In addition, it suggested various options to facilitate uptake and production of these fuels in Singapore.
“We have always proactively wanted to anchor some of these more sustainable options as part of the broader fuel mix available in Singapore,” said Mr Iswaran.
Agencies are also studying how Singapore can produce SAF for both domestic needs and exports, but there are supply constraints.
“One of the things we need to look at is, how we cannot just make it available in sufficient quantities which in itself is a challenge, but also do so in a manner that is cost competitive,” he added.
Being able to produce SAF locally will benefit Singapore-based carriers, as well as other carriers that come to Singapore.
“So long before we talk about physically exporting them to other locations, there are supply chain developments already taking place in Singapore. Our focus is on cost viability and adequate supply,” Mr Iswaran said.
“Once we’re able to work on this and implement this, then it will be available to aviation players in Singapore, based out of Singapore using Changi as a hub, and potentially also for the region.”
The Civil Aviation Authority of Singapore and Singapore-based carriers, such as Singapore Airlines, are monitoring and reporting the airlines’ submissions, under CORSIA, said Mr Iswaran.
