The search for alternatives to reduce high fuel costs in the aviation sector, easyJet has been experimenting with hydrogen fuel cell system to use in their travels on track.
As part of the strategy to reduce the carbon footprint, the easyJet airline, has unveiled plans for a fuel system hydrogen zero emissions in their planes could save 50,000 tons of fuel and associated CO2 emissions.
The system uses a fuel cell hydrogen located in the hold of the aircraft and allow the energy to be captured by the brakes of the aircraft upon landing to load light system batteries when the aircraft is on the ground (as the system of kinetic energy recovery (KERS) that is found in F1 cars).
Through this system, a savings of about 4% of the fuel is achieved, which would allow the company to reduce by about 25 to 35 million annual expenditure for this item. Recall that a third of the cost of airline operations corresponding to fuel consumption.
The energy can be used by the airplane-for example, move- without using its jet engines. Because the lengths of tour operations easyJet, about 4% of all airline fuel consumed annually is used when aircraft of the airline are rolling. The average aircraft easyJet is 20 minutes running time per flight-the equivalent of about 6.4 million km year- like to travel to the moon and back eight times.
Each airplane have engines in its main wheels and electronics and system controllers give pilots total control of aircraft speed, steering and braking during taxi operations. The system would therefore reduce, if not completely eliminate, the need for tugs to maneuver the aircraft in and out of the stands, the delivery of more efficient response times and increased performance over time.
The concept has been developed by award-winning director of engineering easyJet Ian Davies and his team with some of the ideas of the students at the University of Cranfield, who were asked to develop ideas for what air transport could look inside twenty years as part of a contest to celebrate the 20th birthday of easyJet in November 2015.
