Hydrogen H2

Introduction of hydrogen
The H2 molecule of dihydrogen, commonly called hydrogen (not to be confused with the hydrogen atom H), occurs in the form of a gaseous body under normal temperature and pressure conditions. It is also called hydrogen gas.

Hydrogen is also colourless and odourless. It is mainly used in the form of a compressed gas, obtained industrially by reforming hydrocarbons (over 95% of the production comes from fossil fuels), or by the electrolysis of water.

Use of hydrogen
Hydrogen is usually used to produce ammonia (according to the Haber-Bosch process) and in the desulfurization of petroleum fuels. It is also used for the manufacture of hydrochloric acid, welding operations, the reduction works of metal ores and the development of rocket fuels.

We also find H2 as a tracer gas in leak detection operations of several sectors, and as a carrier fluid for certain high-power machines. Hydrogen is also considered as a vector of future energy, capable of replacing hydrocarbons, both due to its possibilities for use and storage.

Risks of hydrogen
H2 is an extremely flammable gas. It can catch fire simply by coming into contact with the air, an ignition source or an oxidiser. Hydrogen can also explode during shock, friction, heating or contact with oxidants.

Although it is not toxic, H2 may be responsible for oxygen depletion in high concentrations.
