For several decades, the aviation industry has been successful in continuously increasing the efficiency of its engines and airframes, resulting in a reduction in emissions per passenger over time.
However, a continuous increase in passenger demand means the increase in overall emissions has outstripped any efficiency gains.
-20%
(CO2 emissions per passenger reduced by 20% since 1990)
+25%
(total CO2 emissions have increased by 25% since 1990 due to increased passenger demand)
Short hop, sub-regional air services have suffered in recent years from the economics of kerosene and the progression to ever larger aircraft to bring the cost per passenger down.
Zero emissions technology can significantly reduce the operating costs of 6-19 seat aircraft, ensuring much needed regional connectivity that is profitable but mitigates environmental impact.
Why Hydrogen for aviation?
Zero CO2
Emissions
Hydrogen has 3X the energy density of conventional aviation fuel and produces zero CO2 emissions the most credible solution for aviation.
30 X energy density of batteries
Batteries have 1/30th of the energy density of hydrogen. Battery solutions therefore come with significant weight penalties, limiting payload and range to levels that struggle to deliver a commercially viable solution.
More Beneficial
than Hybrid
Hybrid-Electric solutions can be beneficial in cars, but the added weight and complexity means their adoption in aircraft results in minimal CO2 benefit.
