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 found that a 50-50 blend of biofuel and aviation fuel reduces jet engine particle emissions by 50 to 70 percent.
- This reduction in particle emissions is expected to directly minimize contrail formation, which currently has a greater impact on Earth’s atmosphere than all aircraft carbon dioxide emissions.
- The research, part of the Alternative Fuel Effects on Contrails and Cruise Emissions Study (ACCESS), involved detailed in-flight measurements using a DC-8 aircraft burning the biofuel blend.
