Introduction
Aviation accounts for 2.5% of global greenhouse gas emissions. To mitigate this, the industry seeks sustainable alternatives. Sustainable Aviation Fuels (SAF) offer a promising solution.
Benefits of SAF
- 80% CO2 emissions reduction
- Renewable sources (biomass, waste)
- Compatibility with existing engines
- Global scalability
- Reduced fossil fuel dependence
- Improved air quality
- Energy diversification
SAF Production Technologies
- Biomass-to-liquid conversion
- Microorganism fermentation
- Waste gasification
- Water electrolysis
- Emerging technologies (algae, bacteria)
- Organic waste utilization
- CO2-based SAF production
Implementations and Projects
- KLM’s SAF-powered flights
- British Airways-Velocys partnership
