According to Airbus, one of the two more conventional designs
seating 120-200 passengers and resembling a modern turbofan
airliner will have a range of 2,000+ NM and be ?capable of
operating transcontinentally and powered by a modified gas-turbine
engine running on hydrogen, rather than jet fuel, through
combustion. The liquid hydrogen will be stored and distributed via
tanks located behind the rear pressure bulkhead.? In its
presentation, Airbus also noted that hydrogen can be used to create
electricity through fuel cells, and that it would use that as a
source to power electric motors.


Burning hydrogen in a gas-turbine engine is no where near pollution
free, as due to the high flame temperature of hydrogen using air
as the oxidizer, burning hydrogen produces enourmous amounts of
nitrogen dioxides, i.e. smog.

Fuel cells run at much lower temperatures and ARE pollution free,
but the technology is not mature enough to power airliners.

Running turbines on hydrogen is a dead end wasted effort as once
the enviro-weinies find out how much smog they produce they will
be banned.

Every time any-one advocates Hydrogen usage in aircraft I think of the
Zeppelin


And that great old song:

There'll be a hot, hot time in Lakehurst, New Jersey,
When the Hindenburg lands today.
The band will start to play, and the people shout hooray,
When the Hindenburg lands today.
Now all the way from Germany you've come unto us,
And we know that your motto is: "To Jersey or Bust"
There'll be a hot, hot time in Lakehurst, New Jersey,
When the Hindenburg lands today;
When the Hindenburg lands today.
