In hybrid solutions the compact electric motor operates at full power during take off allowing for the downsizing of the conventional internal combustion engine and then can be used at lower power, or as a generator during cruise operation
Zero emissions are produced during electric aircraft flight, and electricity can be produced from low or no-carbon sources. Green aviation satisfies stricter emissions regulations, and will not be subject to emissions/fuel taxes.
Electric aircraft have 30-50% lower operating costs compared to traditional combustion aircraft. Refuelling with hydrogen is likely to cost ~ 50% of kerosene, and recharging batteries is likely to cost 5-10x less
Electric aircraft are 90% efficient while conventional combustion aircraft are only 35% efficient. Investment in battery technology is booming for electric mobility and primary energy storage, never so high worldwide
Attractive to climate-conscious consumers, such as the 46% of passengers who would pay ≥2% or more for carbon-neutral flights. Lower noise emissions increase possible locations served, providing passengers with greater travel flexibility
