In a flame of pure hydrogen gas, burning in air, the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and heat. It does not produce other chemical by-products, except for a small amount of nitrogen oxides. Hence a key feature of hydrogen as a fuel is that it is relatively non-polluting (since water is not a pollutant). Pure hydrogen does not occur naturally; it takes energy to manufacture it. Once manufactured it is an energy carrier (i.e. a store for energy first generated by other means). The energy is eventually delivered as heat when the hydrogen is burned. The heat in a hydrogen flame is a radiant emission from the newly formed water molecules. The water molecules are in an excited state on initial formation and then transition to a ground state, the transition unleashing thermal radiation. When burning in air, the temperature is roughly 2000Â°C. Hydrogen fuel can provide motive power for cars, boats and aeroplanes, portable fuel cell applications or stationary fuel cell applications, which can power an electric motor.
The current leading technology for producing hydrogen in large quantities is steam reforming of methane gas (CH4). Other methods are discussed in the Hydrogen Production article. Primarily because hydrogen fuel is environmentally friendly, there are advocates for its more widespread use. At present, however, there is not a sufficient technical and economic infrastructure to support widespread use. The proposed creation of such an infrastructure is referred to as the hydrogen economy.
At the gas pressure that hydrogen is typically stored, hydrogen requires four times more storage volume than the volume of gasoline that produces the equivalent energy, but the weight of this hydrogen is nearly one third that of the gasoline. With regard to safety from unwanted explosions, hydrogen fuel in automotive vehicles is at least as safe as gasoline. The advantages and disadvantages of hydrogen fuel compared to its competitors are discussed at hydrogen economy.

Answers:No. Hydrogen does not support combustion in the sense that oxygen does. Obviously hydrogen will burn in oxygen. There are a few other substances which will support combustion. Those are fluorine, chlorine and to a slight degree bromine. A number of substances will burn in one of those halogens. And hydrogen will burn in each of those three gases, as well.
Answers:No, I'm not quite sure about your question, but only oxygen gas supports combustion and hydrogen sulfide is volatile, but doesn't combust (or undergo combustion) according to our definition of combustion.
Answers:since,wateris a compound and a compound can never show the properties of its constituents.that's why water neither burns itself nor supports combustion.similar example is of iron fillings and sulphur.when we make a mixture of them,they do show their their properties But when a chemical reaction occurs and they together make ironsulphate,the new substanse doesn't show their properties that is ironsulphate is not attracted by magnet.
Answers:1. it will burn 2. yes it is combustible... ever heard of the Zeppelin?? 3. yes you need a supply of air though read previous lol 4. WATER!!! well u need air H2+02....
