Powering jet engines with a 50-50 blend of biofuel and aviation fuel reduces particle emissions in their exhaust by as much as 50 to 70 percent, according to a NASA-led study recently published in the journal Nature.
NASA Confirms Biofuels Reduce Jet Emissions
Key Takeaways:
- NASA-led research found that powering jet engines with a 50-50 blend of biofuel and aviation fuel reduces particle emissions in exhaust by 50 to 70 percent.
- This significant reduction in soot particles is crucial because contrails, which are largely driven by these emissions, have a greater impact on Earth's atmosphere than all carbon dioxide emissions from aircraft.
- The study, part of the ACCESS program, involved in-flight tests with a DC-8 burning a camelina plant oil-based biofuel blend, marking the first quantification of soot emissions from such a mix in flight.
