Parameter

3.1.2.11 SAF powertrain systems

SAF powertrain systems are propulsion configurations optimized to run on high blends or 100% sustainable aviation fuels without requiring modifications to existing fuel networks. These systems provide a critical, drop-in decarbonization pathway that immediately reduces lifecycle carbon emissions. Challenges in developing these systems lie in certifying fuel system elastomer compatibility, ensuring consistent chemical property standards, and scaling up sustainable feedstock supplies.
