Hydrogen - Reactivity of hydrogen | Britannica
Hydrogen - Hydrogen - Reactivity of hydrogen: One molecule of hydrogen dissociates into two atoms (H2 → 2H) when an energy equal to or greater than the dissociation energy (i.e., the amount of energy required to break the bond that holds together the atoms in the molecule) is supplied. The dissociation energy of molecular hydrogen is 104,000 calories per mole—written 104 kcal/mole (mole
Hydrogen Sulphide - an overview | ScienceDirect Topics
Ian Sutton, in Process Risk and Reliability Management, 2010Hydrogen sulfide (H 2 S) Hydrogen sulfide (H 2 S) is a highly toxic chemical compound that is found in a wide variety of oil processing operations. High concentrations of H 2 S may be present in crude oil, molten sulfur, tank and pit-bottom sludge, and produced water, all of which may release the gas if they are agitated, heated, or
Liquid hydrogen (LH 2) is produced by compressing, cooling and expanding Hydrogen. In order to be fully liquid, it must be cooled down to -253°C (-423°F). As this process requires more energy than the compression process per kilogram of hydrogen, it is primarily foreseen for ocean crossing long distance transport with tankers where the construction of pipelines would not be reasonable.

Interstellar medium - Wikipedia
The three-phase model Field, Goldsmith & Habing (1969) put forward the static two phase equilibrium model to explain the observed properties of the ISM. Their modeled ISM consisted of a cold dense phase (T < 300 K), consisting of clouds of neutral and molecular hydrogen, and a warm intercloud phase (T ~ 10 4 K), consisting of rarefied neutral and ionized gas.

Electrolysis of water is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current. This technique can be used to make hydrogen gas, a main component of hydrogen fuel, and breathable oxygen gas, or can mix the two into oxyhydrogen, which is also usable as fuel, though more volatile and dangerous.
