Fuel cell plane for zero emission flying

in environment on (#1D7H7)
story imageBeing the first four-seat passenger plane relying primarily on a hydrogen fuel cell, the HY4 will take off to its maiden flight during the upcoming summer. The powertrain of this twin-fuselage, single-engine plane consists of a hydrogen storage unit, a low-temperature hydrogen fuel cell and a high-performance battery. The fuel cell converts the hydrogen energy directly into electric energy, powering the propeller. The only by-product in this process is pure water. If the hydrogen needed for the conversion process is generated in an electrolysis process powered through renewables, the HY4 flies completely emission-free.

The HY4 powertrain has already been tested successfully in the lab. To create enough lift to take off, the system must provide the maximum takeoff performance reliably for at least three minutes. During the test, the developers already succeeded in running the system for more than ten minutes at maximum power. The interplay between fuel cell and the battery, which unites the functions of an energy buffer and back-up power system, has also been proved. This paves the way to integrate the powertrain into the plane.


Boeing flight-tested the first manned fuel cell aircraft back in 2009.

I have a source of interesting very technical articles, many with an exploration/military twist. Perhaps I should start submitting them, to fan the flames, and help Pipedot become that third party that we all claim to want but never have time to nurture.
Please do :)

Another problem is that there are stories in the pipe, but they don't get upvoted enough to make it to front page (and yes, I'm as guilty as anyone not upvoting stories there).

Of the numbers fifty nine, eight or 84, which is the highest?
