How do we get hydrogen powered aircraft into production?

Question

Both in overcoming technological barriers and transforming energy consumption within communities.

Answer 1

Some years ago I saw concept drawing/pictures of commercial airline aircraft. The fuselage was quite large to increase the storage of hydrogen. The reason being Hydrogen contains less energy per volume the jet fuel.
The cost to retrofit airport refuel systems would big big bucks. While converting to hydrogen you would still need to have jet fuel. If you take in consideration of the life expectancy of a jet airliner, say 30 years, it would very expensive.
How to over come, the will to do it and at a profit.

Answer 2

Well, first you have to develop a reliable, economical source for the fuel, and then an infrastructure capable of supporting it, then you have to develop an aircraft engine capable of running on the stuff and finally, an aircraft capable of using that engine. Then you have to convince the flying public that hydrogen is really a safe fuel for aircraft use...

It ain't gonna happen overnight. Every country in the world has spent the last 100 years building their economy and infrastructures based on machines run by liquid petroleum fuels.

It will take at least that long to convert to something else.

Answer 3

Probably never. Hydrogen may have a future in ground based transportation but aircraft will probably always be liquid fueled -- ethanol is an option there -- due to the weight of the pressurized tanks required to hold the hydrogen.

Also, any thought of any aircraft laden with hydrogen brings back visions of the Hindenberg disaster. People just wouldn't fly on one!

Answer 4

First you have to know that hydrogen produces far less power (for its volume, even after being liquefied) than avgas or kerosene.
That would cause a drastic shortening of the duration of flights to two hours or less for the average passenger jet.
For the same reason, we don't have cars with hydrogen engines -- you'd have to fill up every 100 miles.

Answer 5

That's the one thing I wish I did know. The secret to producing hydrogen cheaply to power anything would transform the world.
Energy is energy. To be able to unlock it from different forms and use it is the key.

Answer 6

hydrogen is as primitive just like oil,

litel bit clean


cehck out some real real overcoming

Answer 7

asking NASA would be a b8r option though.but if u do get an answer frm Yahoo Answers i wud b glad to hear frm u.

Answer 8

our space ships run on hydrogen
