  2. Natural hydrogen - Wikipedia

    en.wikipedia.org/wiki/Natural_hydrogen

    Natural hydrogen (known as white hydrogen, geologic hydrogen, [1] geogenic hydrogen, [2] or gold hydrogen), is hydrogen that is formed by natural processes [3] [4] (as opposed to hydrogen produced in a laboratory or in industry).

  3. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    [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. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [4]

    Most hydrogen production occurs through steam reforming of natural gas; ... The kinetic basis of the low reactivity is the nonpolar nature of H 2 and its weak ...

  5. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Zero carbon emissions 'turquoise' hydrogen is produced by one-step methane pyrolysis of natural gas. [3] Steam reforming of natural gas produces most of the world's hydrogen. Hydrogen is used in the industrial synthesis of ammonia and other chemicals. [4]

    en.wikipedia.org/wiki/Isotopes_of_hydrogen

    Deuterium, 2 H (atomic mass 2.014 101 777 844 (15) Da), the other stable hydrogen isotope, has one proton and one neutron in its nucleus, called a deuteron. 2 H comprises 26–184 ppm (by population, not mass) of hydrogen on Earth; the lower number tends to be found in hydrogen gas and the higher enrichment (150 ppm) is typical of seawater.

    Most hydrogen produced today requires methane, which is a fossil fuel and a strong greenhouse gas contributor. The industry is working on production alternatives, including carbon capture and ...

    For now, the hydrogen that is produced globally each year, mainly for refineries and fertilizer manufacturing, is made using natural gas. That process warms the planet rather than saving it.

  9. Biohydrogen - Wikipedia

    en.wikipedia.org/wiki/Biohydrogen

    Microbial hydrogen production. Biohydrogen is H 2 that is produced biologically. [1] Interest is high in this technology because H 2 is a clean fuel and can be readily produced from certain kinds of biomass, [2] including biological waste. [3]
