Liquid Hydrogen Fuel, and Lithium-Ion Batteries?

Question

Could we use Liquid-Hydrogen as the fuel and Lithium Ion batterys for the propellers.

Is this the way for PASSENGER aircrafts in the near future?

Its our hardest task, a clean aircraft.

Answer 1

If you are going to use batteries for the propellers, what do you need the fuel for?  A clean aircraft would be easy , an electric blimp, except it would be really slow.  People fly when they want to go fast.  In that case, I think propeller planes running on biodiesel will be common when Earth runs out of oil.

Answer 2

Batterys are not safe at all, but i guess its ok for the long time it will take, for them to errode  (^_^)

i think a future for biofuel would be great.. although we are ignorant and using fuel as much as we are food and hence the ignorance of tollerance :P you know upto 300,000 barrels of oil go out weekly just to meet "demands" for everyone in the world....

Answer 3

I have heard talk about liquid hydrogen before.

Liquid hydrogen is easier to contain in a tank because it is cooled and compressed to a liquid state, much thicker than hydrogen gas. One of the problems is the energy it takes to keep it that cold and compressed. Also it might be better to use the H2 to power a jet.

The real problem is keeping it cooled and compressed in tanks light enough to use on an airplane.
