Hydrogen planes are airplanes that use hydrogen as a fuel source.
As an alternative to jet fuel, hydrogen has a higher energy density per unit mass but a lower energy density per unit volume, ...
Hydrogen. The lightest known gas which has been, and still is, extensively used in airships and balloons. Its one great drawback is that it is highly inflammable and this undesirable characteristic has been the cause of many disasters.
HYDROGEN - The lightest known lifting gas, used to inflate balloons and airships, unfortunately highly inflammable.
IATA - International Air Transport Association.
The hydrogen-filled airship was 43 m/144 ft long, had a 2,200-W/3-hp steam engine that drove a three-bladed propeller, and was steered using a saillike rudder. It flew at an average speed of 5 kph/3 mph.
Water molecules can be created from scratch by chemical processes, for instance by burning hydrogen or hydrocarbons.

Boeing has announced last April 03, 2008 that it has successfully managed
to fly a manned airplane powered by hydrogen fuel cells.
Petroleum, or crude oil, is a hydrocarbon (a chemical compound containing hydrogen and carbon) that can be distilled into gasoline, kerosene, oils and waxes. Hydrocarbons are formed from large deposits of decomposed plant and animal matter.
The main principle of Zeppelin's invention was that hydrogen-filled gas-bags were carried inside a steel skeleton.
Welding it with TIG is much easier and is readily available as an outside skill at your local welding shop. Hydrogen welding with a torch is even easier, ...
The gases up there are extremely thin and there is not much oxygen, mostly hydrogen. Conventional aircraft, like piston-engine or jet, are unable to travel to the exosphere.
A complete combustion is a process that converts all carbon (C) to carbon dioxide (CO2), all hydrogen (H) to water (H2O), and all sulfur (S) to sulfur dioxide (SO2).
Environment: Environmental conditions can cause erosion, corrosion, or hydrogen embrittlement may all affect fatigue life. Corrosion fatigue is a problem encountered in many aggressive environments.
