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:
- A NASA-led study revealed that powering jet engines with a 50-50 blend of biofuel and aviation fuel reduces particle emissions in exhaust by 50 to 70 percent.
- These particle reductions are crucial because contrails, formed from hot engine exhaust and composed primarily of ice crystals, have a greater impact on Earth’s atmosphere than all carbon dioxide emissions from aircraft.
- Minimizing soot emissions directly translates to reduced ice crystal concentrations in contrails, which in turn helps to lessen their overall environmental impact.
