As a major aviation hub, Australia faces a dual challenge of high fuel import dependency (projected to exceed 80% by 2030) and the urgent mandate for a 2050 net-zero transition. While Australia possesses abundant biomass feedstocks, current commercial SAF production via Hydroprocessed Esters and Fatty Acids (HEFA) is limited by feedstock availability and high costs. Transitioning to a domestic, biomass-derived SAF industry is critical for energy resilience and carbon neutrality.Traditional thermochemical upgrading via hydrodeoxygenation (HDO) requires severe operating conditions (up to 340°C and 6 MPa H2), leading to high energy intensity and capital costs. This research explores an alternative electrochemical route to upgrade biomass-derived platform chemicals into high-grade SAF components under ambient conditions.Our study focuses on the electrochemical transformation of oxygenated platform molecules into long-chain hydrocarbons. Utilizing customized electrolyzers and renewable-energy-compatible processes, we have successfully identified reaction pathways that yield products within the C8–C18 range, directly matching the carbon chain requirements for jet fuel. Advanced analytical techniques are employed to monitor the formation of complex structures, including iso-paraffins and bicyclo-paraffins, which are essential for enhancing SAF blending ratios and engine compatibility. Preliminary results demonstrate the feasibility of achieving C-C coupling and deoxygenation at near-ambient temperatures (20–60°C). While initial detection confirms the presence of desired hydrocarbon fractions, current efforts are centered on the systematic optimization of catalyst design and reaction parameters to further enhance product yield and selectivity. This exploratory work addresses the limitations of conventional HDO by bypassing the need for fossil-derived high-pressure hydrogen. This research establishes a foundational framework for a scalable, green-electricity-driven SAF production strategy. By leveraging Australia’s local biomass resources and mild electrochemical processing, this approach offers a promising pathway toward a more self-sufficient and sustainable aviation future.
