  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] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.

  3. 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.

  4. Hydrogen storage - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_storage

    Compressed hydrogen is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology.

  5. Hydrogen internal combustion engine vehicle - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_internal...

    As hydrogen combustion occurs in an atmosphere containing nitrogen and oxygen, however, it can produce oxides of nitrogen known as NO x. In this way, the combustion process is much like other high temperature combustion fuels, such as kerosene, gasoline, diesel or natural gas. Therefore, hydrogen combustion engines are not considered zero emission.

  6. H2 - Wikipedia

    en.wikipedia.org/wiki/H2

    H 2, the chemical formula for hydrogen gas (dihydrogen) Deuterium (Hydrogen-2, H-2, 2 H), the isotope of hydrogen with one proton, one neutron, and one electron Other uses in science and mathematics

  7. Hydrogen purification - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_purification

    Hydrogen purification is any technology used to purify hydrogen. The impurities in hydrogen gas depend on the source of the H2, e.g., petroleum, coal, electrolysis, etc. The required purity is determined by the application of the hydrogen gas. For example, ultra-high purified hydrogen is needed for applications like proton exchange membrane ...
