Singapore Airlines Inks Three-Year Deal for 4,800 Tonnes of Next-Gen SAF from Aether's Project Beacon at Pulau Bukom Starting 2028

Singapore Airlines has finalized a landmark three-year agreement with Aether Beacon Pte Ltd to procure up to 4,800 tonnes of next-generation sustainable aviation fuel derived from industrial waste gases and biomethane, establishing the flag carrier as the anchor airline partner for Project Beacon on Pulau Bukom with deliveries beginning in 2028.

The binding offtake contract marks a decisive step in Singapore Airlines' (SIA) roadmap toward net-zero carbon operations by 2050. By committing to Project Beacon—Aether’s commercial production facility sited within Aster’s energy and refining complex on Pulau Bukom—the airline broadens its procurement beyond conventional lipid-derived biofuels into advanced synthetic drop-in fuels engineered from recycled industrial emissions.

Strategic Anchor for Southeast Asia's Emerging SAF Ecosystem

Project Beacon represents Singapore's bid to become an advanced alternative fuel hub in the Asia-Pacific region. Under the three-year offtake arrangement scheduled to initiate supply in 2028, Singapore Airlines secures direct access to up to 4,800 tonnes of certified low-carbon jet fuel manufactured locally.

The agreement validates the commercial viability of next-generation sustainable aviation fuel (SAF) production in Singapore, providing the guaranteed demand profile needed to advance capital deployment for waste-to-fuel infrastructure. Rather than relying solely on imported renewable fuels, the local supply chain established on Pulau Bukom links maritime refining infrastructure directly with Singapore Changi Airport’s international departure network.

Technical Architecture: Aurora Fischer-Tropsch Process vs Traditional HEFA

A central dimension of the SIA-Aether agreement lies in the shift toward non-lipid feedstocks. Modern commercial SAF production remains heavily dominated by Hydroprocessed Esters and Fatty Acids (HEFA), a technology reliant on used cooking oil, animal tallow, and vegetable oils. The HEFA pathway faces mounting global supply constraints and feedstock price volatility as international mandates expand.

In contrast, Aether’s proprietary Aurora technology adapts the established Fischer-Tropsch (FT) conversion platform to process diverse waste-derived carbon feedstocks. By utilizing biomethane captured from organic processing alongside gaseous industrial off-gas streams from manufacturing clusters, the system synthesizes high-energy liquid hydrocarbons without diverting agricultural land or competing for culinary waste oils.

Metric / Dimension	Traditional HEFA Pathway	Aether Aurora Fischer-Tropsch Pathway
Primary Feedstocks	Used cooking oil (UCO), animal fats, vegetable oil	Industrial waste gases, biomethane, captured carbon
Feedstock Availability	Geographically constrained; high market competition	Abundant industrial byproduct streams
Chemical Conversion	Hydroprocessing and deoxygenation of triglycerides	Catalytic reforming and Fischer-Tropsch synthesis
Fuel Properties	Drop-in paraffinic kerosene blend component	Drop-in synthetic kerosene identical to conventional Jet A-1
Emissions Compliance	Meets CORSIA baseline thresholds	Certified under ICAO CORSIA standards
Production Footprint	Concentrated in agricultural and oil recovery centers	Co-located with industrial and petrochemical clusters

The resulting synthetic paraffinic kerosene meets all ASTM D7566 specifications, allowing seamless drop-in blending with conventional fossil-based Jet A-1 at ratios up to 50% without requiring any modifications to aircraft engines, wing fuel tanks, or airport hydrants.

Scaling Roadmap: Pulau Bukom to the 2031 Megaplant

Project Beacon serves as the operational springboard for Aether's long-term commercialization strategy. The company has formally outlined plans to establish its first large-scale commercial manufacturing facility by 2031.

The planned 2031 commercial complex is engineered to achieve a production capacity at least ten times (10x) greater than that of Project Beacon. This phased scale-up addresses one of the fundamental hurdles facing global aviation: the acute shortage of commercially scaled SAF output. By demonstrating high-efficiency conversion rates at Project Beacon through 2028 and subsequent years, Aether aims to de-risk broader debt financing and project equity for industrial-scale deployment across international trade lanes.

The integration into Aster’s Pulau Bukom refining complex delivers immediate operational efficiencies. Aster’s established utility networks, deepwater marine jetties, and storage terminals streamline raw gas intake and downstream fuel handling, demonstrating how legacy petroleum refining assets can pivot toward low-carbon fuels without requiring entirely greenfield construction.

Executive Perspectives on Procurement and Industrial Scaling

Leadership from both Singapore Airlines and Aether Fuels emphasized that long-term offtake commitments represent the prerequisite for establishing resilient alternative fuel supply chains.

Ms Lee Wen Fen, Chief Sustainability Officer at Singapore Airlines, highlighted the role of targeted procurement in achieving the airline’s environmental milestones:

"Supporting the development and adoption of SAF, and securing future supplies, are integral to SIA’s ambition of achieving net zero carbon emissions by 2050. As the first airline to purchase SAF from Project Beacon, SIA is demonstrating demand for new lower-carbon fuel production pathways in Singapore. We will continue to work with partners globally to scale SAF production, strengthen the aviation industry’s sustainability ecosystem, and support the transition to more sustainable air travel."

Mr Conor Madigan, Co-Founder and Chief Executive Officer of Aether Fuels, reflected on the rapid progression from initial discussions to a legally binding commercial agreement:

"When we signed our MOU with Singapore Airlines last year, Project Beacon had not yet been announced. Since then, we have selected Singapore as the home of our first commercial facility and built critical partnerships across the local value chain. Singapore is building a strong ecosystem for aviation decarbonisation through refining and aviation infrastructure, investment support, sustainability policies, and utilising their position as a global aviation hub. This binding agreement is an important next step and a strong signal of committed demand from a leading global airline – exactly the type of collaboration needed to create the commercial conditions to bring new SAF pathways to scale."

Global Aviation Decarbonization and CORSIA Compliance

The SAF supplied under this contract will carry full certification under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), established by the International Civil Aviation Organization (ICAO). Under CORSIA rules, airlines operating international routes must report baseline emissions and offset growth through eligible emissions units or through the verified combustion of certified lower-carbon aviation fuels.

Because waste-derived synthetic kerosene recycles carbon that would otherwise vent directly into the atmosphere as carbon dioxide or methane, its full lifecycle greenhouse gas footprint is substantially lower than fossil jet fuel. Singapore’s progressive SAF blending policies—which mandate an escalating percentage of sustainable aviation fuel on departures from Changi Airport—create a supportive domestic framework for early adopters like Singapore Airlines.

By securing volume commitments through 2028, SIA hedges against future compliance penalties while diversifying its procurement portfolio across multiple chemical pathways. As aviation regulators across Europe, North America, and Asia enact stricter blending mandates, contracts tied to Fischer-Tropsch waste gas conversion provide a viable blueprint for long-haul carriers seeking dependable, lipid-independent fuel volumes.
