Singapore Airlines Group (SIA) has entered into an agreement with Aether Fuels, a climate technology firm, to secure future supplies of neat sustainable aviation fuel (SAF). The Memorandum of Understanding (MoU) outlines SIA’s intent to purchase SAF for five years once Aether’s production facilities in the U.S. and Southeast Asia reach commercial scale, with an option to extend for another five years.
Aether’s SAF will be blended with conventional jet fuel and distributed to select airports serving Singapore Airlines and its low-cost carrier subsidiary, Scoot. The fuel will be produced using Aether’s proprietary Aurora™ technology, designed to lower capital costs, improve production efficiency, and yield higher SAF volumes than conventional methods.
Lee Wen Fen, Chief Sustainability Officer at Singapore Airlines, highlighted the deal’s significance: “This partnership marks another step in the SIA Group’s journey towards our long-term decarbonisation goal of net zero carbon emissions by 2050. By collaborating with like-minded ecosystem partners such as Aether, we aim to accelerate and scale up the adoption of SAF in our flight operations, laying the groundwork for more sustainable air travel.”
Aether, founded in 2022 and incubated by Xora, a deep-tech venture firm backed by Temasek, has rapidly expanded its footprint in Southeast Asia and the U.S. Its upcoming commercial-scale production facilities will generate SAF certified under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), with a targeted minimum 75% reduction in greenhouse gas emissions.
Conor Madigan, CEO of Aether Fuels, emphasized the impact of the agreement: “We are proud to join the SIA Group’s ecosystem of SAF technology innovators. Their decarbonisation goals are catalysing ingenuity throughout the supply chain and galvanising companies like Aether to develop production solutions that pair breakthrough technologies with next-generation feedstock strategies. The collaboration will deepen our understanding of the end-user customer priorities and of the SAF market, particularly in South East Asia.”
“This collaboration with the SIA Group reflects a shared focus and commitment, making it a natural fit that will undoubtedly accelerate SAF innovation and adoption.”
Phil Inagaki, Managing Partner and Chief Investment Officer of Xora and Board Chair of Aether Fuels, noted Singapore’s role in fostering SAF innovation: “Singapore has built a supportive environment for deep tech innovation, empowering companies like Aether to amplify the impact of transformative solutions to global challenges. This collaboration with the SIA Group reflects a shared focus and commitment, making it a natural fit that will undoubtedly accelerate SAF innovation and adoption.”
By securing SAF supply from a next-generation producer, Singapore Airlines is reinforcing its commitment to long-term decarbonization and supporting the commercial scalability of new SAF technologies.
