The British low-cost airline easyJet has proposed a concept for a new passenger hybrid aircraft, where electric motors are supposed to be used along with supporting turbojet engines. They will be installed in the chassis for use when taxiing on the runway.
Hydrogen fuel cells will generate energy to power electric motors. According to the head of easyJet, Ian Davis, there will be applications for the water that is formed as a result of hydrogen waste. Since it is completely clean, it can be used for drinking or, as a last resort, for flushing toilets.
The operation of the engines will be completely under the control of the crew. As a result, there is no need for special tugs to ensure the delivery of the liner to the start of takeoff.
EasyJet estimates that taxiing operations currently consume up to 4% of fuel consumption. Thanks to the innovation, it will be possible to save up to 50, 000 tons of fuel annually.
The hybrid aircraft is a collaboration between easyJet and Crenfield University. The airline says a test plane will appear later this year, and scheduled flights could begin in the next decade.
