easyJet reveals concept designs for hybrid plane

UK airline easyJet has unveiled plans for a revolutionary zero emissions hydrogen fuel system for its aircraft which could save around 50,000 tonnes of fuel and the associated CO2 emissions per year.

easyJet set new carbon reduction 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 kilometre.

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. ‎‎

For the hybrid plane concept the airline has taken inspiration from students at Cranfield University, a global leader in education and research in technology and management, who were asked to develop ideas for what air travel might look like in twenty years’ time, as part of a competition to celebrate easyJet’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.

This innovative zero-emissions system allows energy to be captured as the aircraft brakes on landing and is used to charge the system’s lightweight batteries when the aircraft is on the ground (much like the Kinetic Energy Recovery System (KERS) found in Formula 1 cars).

Due to the high frequency and short sector lengths of easyJet’s operations, around 4% of the airline’s total fuel consumed annually is used when the airline’s aircraft are taxiing.  easyJet averages 20 minutes of taxi time per flight – the equivalent of around four million miles a year.

The system would therefore reduce, if not remove, the need for tugs to manoeuvre 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 aircraft’s water system throughout the flight.

The concept has been developed by easyJet’s award winning engineering director Ian Davies and his team working with some of the ideas from students combined with easyJet’s own conceptual thinking.

Davies said: “At 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. It’s also a great example of the benefits of our strategic relationship with Cranfield University.”

Dr. Craig Lawson, Lecturer, Centre for Aeronautics, Cranfield University, added: “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. We’re looking forward to developing this concept further.”

easyJet and Cranfield University signed a three year strategic partnership agreement last year to share innovation and knowledge.

easyJet operates a fleet of over 240 Airbus A319s and A320s with an average age of just 6 years old. The airline will start taking delivery of A320neo aircraft from June 2017 and the new planes will be around 13% – 15% more fuel efficient than the aircraft they are replacing.
