easyJet reveals concept designs for hybrid plane
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 tonnes of fuel and the associated CO2 emissions per year.

Rather than use a highly volition fuel cell (Apollo 13) the electrical motors should be powered by the APU in the tail. It's not as clean as a cell but from an overall emissions basis you will still be ahead vs. two idling jet engines.

What is the added system weight? The airplane has to burn fuel to keep it airborne between stations. I get the goal of not having to run the big engines to taxi. But to me adding weight to the airplane rings a dull bell. How about considering a new generation of lighter and more efficient APU to provide power to a similarly efficient electric drive. I thinking a lower weight penalty system has to be better.
Why not use the electric front gear drive system already being used ?
Oh yeah, Hydrogen on an aircraft. Anyone ever see the last landing of the Hindenburg? It did not go well.
CO2 emissions are not the boogey man politicians like Sen. Sanders and the politically motivated "scientists" scream about with their hair on fire.
There is no shortage of fossil fuel, and humans will never overtake the production rate of new fuel by natural processes powered by the sun.
It seems silly to waste resources of time and materials to produce a system to counter the effect of CO2 in the atmosphere. It is not a problem, then, now, or ever. There is a cult like group of politicians that want to pick your pocket and make themselves rich.

Hindenburg actually had little to do with the hydrogen. It was landing with thunderstorms in the area and the skin of the vehicle was very combustible. The result would have been the same with helium, with slightly less initial fire. Google Addison Bain.
The hydrogen fuel process is nothing like the airbag gas state of the Hindenburg in 1937. It is still safer then avgas of jet fuel. The only issue the need to get past is hydrogen is made from either fossil fuel sources or electricity. Unless hydrogenated there is still the extra use of fossil fuels or nuclear power.
