  2. Hydrogen safety - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_safety

    The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ...

    H, also called protium) that makes up most of the hydrogen in normal water. [3] The presence of the heavier isotope gives the water different nuclear properties, and the increase in mass gives it slightly different physical and chemical properties when compared to normal water. Deuterium is a heavy hydrogen isotope.

  4. Liquid hydrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_hydrogen

    Since water is often considered harmless to the environment, an engine burning it can be considered "zero emissions". In aviation, however, water vapor emitted in the atmosphere contributes to global warming (to a lesser extent than CO 2). [11] Liquid hydrogen also has a much higher specific energy than gasoline, natural gas, or diesel. [12]

  5. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    Hydrogen is extremely flammable. Some countries have banned the use of hydrogen as a lift gas for commercial vehicles but it is allowed for recreational free ballooning in the United States, United Kingdom and Germany. The Hindenburg disaster is frequently cited as an example of the safety risks posed by hydrogen. The extremely high cost of ...

    The use of acid-resistant gloves and face shield is recommended for safe handling; fume hoods are another effective control of such substances. [4] Water-reactive substances are classified as R2 under the UN classification system and as Hazard 4.3 by the United States Department of Transportation.

  7. Hydrogen transport - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_transport

    Hydrogen can be reacted with other elements to form a variety of compounds. This allows it to be transported in either liquid (e.g., water) or solid form. One variation on this concept is to transport atomic silicon, produced using renewable energy .

    en.wikipedia.org/wiki/Water

    Water and other volatiles probably comprise much of the internal structures of Uranus and Neptune and the water in the deeper layers may be in the form of ionic water in which the molecules break down into a soup of hydrogen and oxygen ions, and deeper still as superionic water in which the oxygen crystallizes, but the hydrogen ions float about ...

  9. 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.
