Several supply offers for many industries and applications

Hydrogen is the lightest gas in the world and therefore is not held by the earth’s gravity.

Hydrogen is only found in the atmosphere at trace levels; reason why it is synthesized from hydrocarbons (petroleum and petroleum by-products) or from water, where it constitutes the lightest fraction of the H2O molecule.

Hydrogen gas is colorless, highly flammable, very light, cannot sustain life and reacts easily with other chemical substances.
