Decarbonisation Technology May 2026 Issue

Technology strength, when framed as industrial robustness and lifecycle commitment, is not promotional. It is structural to workable partnerships. Feedstock security as a design discipline Feedstock flexibility is a strategic advantage, but it must be engineered deliberately. A feedstock-agnostic syngas platform can process biomass residues, municipal solid waste, CO 2 , and natural

waste oils through hydrotreated esters and fatty acid (HEFA) processes. These were pragmatic starting points. However, feedstock limitations are evident. Policymakers in Europe have introduced caps on HEFA volumes, accelerating diversification towards advanced routes. Advanced pathways based on syngas platforms require integration of hydrogen production, carbon capture, and catalytic upgrading. Synthetic fuels projects that combine renewable hydrogen with captured CO 2 and convert that mixture into drop- in fuels demonstrate that power-to-liquids configurations are moving beyond commercial deployment. The importance of these projects lies not only in chemistry but in partnership alignment. Energy companies, technology providers, and engineering partners operate within supportive policy frameworks. Demonstration plants provide operational data, operational data reduces perceived technology risk, and reduced risk enables financing. Demonstration projects are therefore institutional milestones as much as technical ones. Demand, risk and financial architecture Airlines have evolved from passive customers into structural partners in SAF deployment. Large airline groups are centralising procurement and entering long-term offtake agreements extending beyond a decade. These contracts provide the revenue certainty required for project finance. Aggregated procurement

gas. This flexibility increases resilience against supply fluctuations and regional constraints. In India, agricultural residues that are currently burned in fields could become valuable feedstocks for SAF. In other regions, forestry residues present a similar opportunity. Municipal waste streams, when treated as feedstock rather than waste, strengthen circular economy models and create economic incentives for collection and sorting. However, variability in feedstock composition affects gasifier performance, syngas cleaning requirements, and downstream catalyst life. Moisture content, ash composition, and trace contaminants must be managed. Contracts must define quality tolerances. Supply chains must be secured early. Digital monitoring and robust catalyst systems mitigate variability but cannot compensate for poorly structured upstream agreements. Projects that treat feedstock as an afterthought frequently encounter delays between feasibility and FID. Projects that embed feedstock strategy within engineering design and financing structures are far more resilient. SAF as a stress test Aviation provides a clear stress test for partnership models. Aircraft fleets represent long-duration capital assets. SAF is the most immediate pathway to reduce lifecycle emissions at scale without waiting for disruptive propulsion technologies. The first generation of SAF relied heavily on
