easyJet to Test Fly Hybrid Aircraft in 2016
As part of its strategy of reducing its passengers' carbon footprint EasyJet has unveiled plans for a revolutionary zero emissions hydrogen fuel system for its aircraft which could save around 50,000 tons of fuel and the associated CO2 emissions per year. easyJet is committed to reducing its passengers' carbon footprint and has set new targets for 2020 which will see a reduction of 7% over the next five years compared to its emissions today, which are 81.05 grams CO2 per passenger kilometer.
This follows a decrease of 28% over the last 15 years. easyJet invests in the latest technology, operates efficiently and fills most of its seats which means that an easyJet passenger's carbon footprint is 22% less than a passenger on a traditional airline, flying the same aircraft on the same route. â€Žâ€Ž
For the hybrid plane concept the airline has taken inspiration from students at Cranfield University, who were asked to develop ideas for what air travel might look like in twenty yearsâ€™ time, as part of a competition to celebrate easyJetâ€™s 20th birthday in November 2015. easyJet will now work with its industry partners and suppliers to apply the cutting edge technology much sooner with a trial set to take place later this year.
The hybrid plane concept utilizes a hydrogen fuel cell stowed in the aircraft's hold. This innovative zero-emissions system allows energy to be captured as the aircraft brakes on landing and is used to charge the systemâ€™s lightweight batteries when the aircraft is on the ground (much like the Kinetic Energy Recovery System (KERS) found in Formula 1 cars).
The energy can then be used by the aircraft â€“ for example when taxiing - without needing to use their jet engines. Due to the high frequency and short sector lengths of easyJetâ€™s operations, around 4% of the airlineâ€™s total fuel consumed annually is used when the airlineâ€™s aircraft are taxiing. easyJetâ€™s aircraft average 20 minutes of taxi time per flight â€“ the equivalent of around four million miles a year â€“ akin to travelling to the moon and back eight times.
Each aircraft would have motors in their main wheels and electronics and system controllers would give pilots total control of the aircraftâ€™s speed, direction and braking during taxi operations. The system would therefore reduce, if not remove altogether, the need for tugs to manoeuver aircraft in and out of stands, delivering more efficient turnaround times and increased on time performance.
The only waste product is fresh clean water which could be used to refill the aircraftâ€™s water system throughout the flight. The concept has been developed by easyJetâ€™s award winning engineering director Ian Davies and his team working with some of the ideas from students combined with easyJetâ€™s own conceptual thinking.
Head of Engineering, easyJet, Ian Davies, commented: â€œAt easyJet, we are continuing to apply the use of new digital and engineering technologies across the airline. The hybrid plane concept we are announcing today is both a vision of the future and a challenge to our partners and suppliers to continue to push the boundaries towards reducing our carbon emissions. Itâ€™s also a great example of the benefits of our strategic relationship with Cranfield University.â€
Dr. Craig Lawson, Lecturer, Centre for Aeronautics, Cranfield University, added: â€œWe are delighted to be working on this project with easyJet on what is a real-world example of how we can innovate together. Cranfield is a specialist postgraduate university providing advanced, practical education and research. We are recognized internationally as meeting the needs of business, governments and wider society. Our students have showcased some exciting ideas for the 2035 vision of the airline industry through The Future of Flight competition, presenting environmental solutions, operational improvements and ideas to enhance the customer experience. Weâ€™re looking forward to developing this concept further.â€
easyJet and Cranfield University signed a three-year strategic partnership agreement last year to share innovation and knowledge. As part of easyJetâ€™s 20th birthday activities, students at Cranfield University were asked to compete in four categories; cabin design, aircraft design, airport experience and in-flight experience.
Judges at easyJet and Cranfield received a raft of pioneering advances from the aerospace students. Further innovative ideas included dynamic wings which change shape in flight, a super-efficient 'shark skin' coating to reduce surface drag and, in the cabin, ultra-light weight seats carbon fiber seats incorporating wireless phone and tablet charging panels.
