Aviation Ping!....................
Battery humpers won’t like that lol
“Oh the humanity!”

And behind the scenes? Grants and subsidies from government.
Some chick is going to get on with a staticky sweater and — BOOM!
It sounds like they only carry the hydrogen and the oxygen comes from the air. An internal combustion engine does the same thing, but more than oxygen anlways ends up getting involved. I would expect the same, here, unless the fuel-cell is, somehow, more selective.
Of course, this may all be moot, as they probably burn fossil fuels to create the hydrogen in the first place.
Hydrogen fuel cells produce electricity. So how is this supposed to run a jet engine? Or is the author not familiar with the technology?
Science says CO2 is not a poison.
If the fuel cell works, fine. But wouldn’t a high-velocity propeller connected to the shaft of an electric motor work better than burning the hydrogen for jet engine thrust?
As a conversion of the energy in the fuel to forward propulsion, it would be extremely wasteful to consume the hydrogen to create thrust by heating air to high temperatures. Hydrogen does not store nearly so compactly as liquid petroleum fuels.
The article doesn’t get into the specifics of the engine. I am assuming it will be similar to the turbo prop (short distance) and turbo fan (long distance) except that the propeller or fan will be driven by an electric motor.
Very big waste of time and money right now
Airbus’s answer to the growing demand [On the part of about .0001 of the population] for sustainable aviation technologies.
My college thermo class was taught by a genuine NASA scientist. He had the class work through complicated applications of all the Green energy schemes we see today. Even given the most generous assumptions none of them beat just using plane old oil-based energy.
Any time.................
The output of a fuel cell is electricity. There is no combustion that produces a jet of hot gases. It’s basically a hydrogen powered battery.
“ Very big waste of time and money right now”
Why ?
There’s tons of Jet Fuel out there and that plane is a BUST always was
So they're saying there might be a bigger one we don't know about?
Yes. And Liquid hydrogen is hard to contain, and imagine the fireball if the plane crashes for mechanical reasons.
The power density of hydrogen is not good.
Another issue? Range. How far can a plane fly with that kind of fuel supply.
It is probably like electric cars, very short range.
There is no free lunch when it comes to power.
