  2. Hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen

    Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.

  3. Hydrogen evolution reaction - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_evolution_reaction

    Hydrogen evolution reaction (HER) is a chemical reaction that yields H 2. [1] The conversion of protons to H 2 requires reducing equivalents and usually a catalyst. In nature, HER is catalyzed by hydrogenase enzymes. Commercial electrolyzers typically employ supported platinum as the catalyst at the anode of the electrolyzer.

  4. Natural hydrogen - Wikipedia

    en.wikipedia.org/wiki/Natural_hydrogen

    Natural hydrogen is generated from various sources. Many hydrogen emergences have been identified on mid-ocean ridges. [22] Serpentinisation occurs frequently in the oceanic crust; many targets for exploration include portions of oceanic crust which have been obducted and incorporated into continental crust.

  5. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    Hydrogen gas is produced by several industrial methods. [1] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [2] [3]: 1 Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas.

  7. Diatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Diatomic_molecule

    The natural abundance of hydrogen (H 2) in the Earth's atmosphere is only of the order of parts per million, but H 2 is the most abundant diatomic molecule in the universe. The interstellar medium is dominated by hydrogen atoms.
