Episode notes
INSIGHT

Fuel Cells Beat Combustion Pollution

  • Hydrogen fuel cells avoid combustion, reducing particulate and NOx pollution around airports.
  • They are more efficient than combustion engines and cheaper than synthetic fuels, making them the best decarbonization option for aviation.
INSIGHT

Hydrogen Outperforms Batteries in Energy

  • Hydrogen's chemical energy density per weight is about three times that of theoretical lithium battery limits.
  • This large gap in specific energy explains why hydrogen fuel cells outperform batteries for aviation's energy demands.
INSIGHT

Fuel Cells Cut Engine Maintenance

  • Small combustion engines in 10-20 seat planes require overhaul every 4,000 hours.
  • ZeroAvia fuel cell engines can operate 10,000 hours between major overhauls and electric motors last the plane's lifetime, lowering maintenance.
