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.

But the devil is in the details. It sounds like it would augment energy capture by a regenerative braking system. What electolyte woud the cell use? Some get quite hot.

Looks to be the way to go and less combustible in an accident.
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.
Why not use the electric front gear drive system already being used ?
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.
