It is common knowledge that lead-acid batteries, when they are charging, release hydrogen gas that can potentially result in an explosion. In 2001, a hydrogen gas explosion occurred in a California data center in the UPS room where batteries were charging. room where batteries were charging.
Norway''s Equinor favors blue hydrogen developments …
The initial phase of Equinor''s UK blue hydrogen project would comprise a 600-MW auto thermal reformer with carbon capture, the largest plant of its kind in the world, to convert gas to hydrogen. According to an Equinor spokesman, hydrogen production capacity for such a plant would be around 125,000 mt a year.
Hydrogen sulfide - Wikipedia
Hydrogen sulfide is often produced from the microbial breakdown of organic matter in the absence of oxygen gas, such as in swamps and sewers; this process is commonly known as anaerobic digestion which is done by sulfate-reducing microorganisms.H 2 S also occurs in volcanic gases, natural gas, and in some sources of well water.
Hydrogen chloride - Wikipedia
The resulting hydrogen chloride gas is either reused directly or absorbed in water, resulting in hydrochloric acid of technical or industrial grade. Laboratory methods [ edit ] Small amounts of HCl gas for laboratory use can be generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride .

Hydrogen station - Wikipedia
A hydrogen station is a storage or filling station for hydrogen, usually loed along a road or hydrogen highway, or at home as part of the distributed energy resources (DER) concept. The stations are usually intended to provide fuel for hydrogen-powered vehicles, but the hydrogen can also be used to power small devices. 
Hydrogen | Encyclopedia
Hydrogen gas consists of diatomic (two-atom) molecules, with the formula H 2. It is the lightest of all known substances. There is only about 0.05 part per million of hydrogen gas in the air. It rises to the top of the atmosphere and is lost into space.

Assuming a feedstock cost of $40/MWh, for example, PEM electrolysis-derived hydrogen (at a 70% capacity factor) costs around $3.30/kg compared with $1.50/kg for blue hydrogen production (with $3.50/Mtu natural gas), it said.
Hydride | chemical compound | Britannica
Hydride, any of a class of chemical compounds in which hydrogen is coined with another element. Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved. A fourth type of hydride, dimeric hydride, may also be identified on the basis of structure (see borane).
