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 ...
NASA’s Artemis I launch has been delayed twice because of liquid hydrogen problems. It’s not a new one for the space agency. Meanwhile, SpaceX has switched to methane. WSJ explains why NASA ...
Now, researchers are using a model accounting for the rate at which hydrogen is produced underground by natural processes to estimate the volume of the gas that could be trapped in the subsurface.
Engineers are reviewing test data to determine if NASA can press ahead toward a September 27 launch target. NASA copes with hydrogen leak, fuels Artemis moon rocket in critical test Skip to main ...
Addison Bain is a retired NASA scientist [1] and founding member of the National Hydrogen Association [2] who is credited with postulating the Incendiary Paint Theory (IPT), which posits that the Hindenburg disaster was caused by the electrical ignition of lacquer- and metal-based paints used on the outer hull of the airship.
Liquid hydrogen (H 2 (l)) is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H 2 form. [4] To exist as a liquid, H 2 must be cooled below its critical point of 33 K. However, for it to be in a fully liquid state at atmospheric pressure, H 2 needs to be cooled to 20.28 K (−252.87 °C; −423.17 °F). [5]
Hydrogen fuel cell cars like the Toyota Mirai contain Kevlar-armored tanks that store hydrogen at 700 times the pressure of the Earth’s atmosphere. But this is hard to do on a large scale for ...
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.
