Sustainable Aviation: SAF, Electrification and Hydrogen Pathways
Decarbonizing aviation will require a portfolio approach. SAF, electrification, and hydrogen propulsion each plays a role depending on mission type, range and infrastructure readiness.
Sustainable Aviation Fuels
SAFs deliver near-term emissions reduction with minimal aircraft changes, but global supply and economics remain the limiting factors. Scaling production and enabling higher blend ratios are decisive priorities for the next decade.
Electrification
Battery-electric aircraft will first serve short-range commuter and training missions. Hybrid-electric designs are expected to arrive earlier than full electric for larger aircraft, reducing fuel burn through electric assist during high-power phases.
Hydrogen Propulsion
Hydrogen offers a route to near-zero CO₂ at the point of use, but storage, infrastructure, and certification complexity push broad adoption later—especially for larger commercial segments.
