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.
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.
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.
