Hydrogen
41Hydrogen safety — covers the safe use and handling of hydrogen. Hydrogen poses unique challenges due to its ease of leaking, low energy ignition, wide range of combustible fuel air mixtures, buoyancy, and its ability to embrittle metals that must be accounted for… …
42Hydrogen technologies — are technologies that relate to the production and use of hydrogen. Hydrogen technologies are applicable for many uses.Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen …
43Hydrogen cyanide — IUPAC name …
44Hydrogen planes — are airplanes that use hydrogen as a fuel source.As an alternative to jet fuel, hydrogen has a higher energy density per unit mass but a lower energy density per unit volume , and containing the hydrogen at high pressure would require a heavy… …
45Hydrogen fuel enhancement — is the process of using a mixture of hydrogen and conventional hydrocarbon fuel in an internal combustion engine, typically in a car or truck, to improve fuel economy, power output, or both. While the term may be used to refer to different ways… …
46Hydrogen pipeline transport — is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure.EconomicsHydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport… …
47Hydrogen disulfide — Hydrogen disulfide …
48Hydrogen leak testing — is the normal way in which a hydrogen pressure vessel or installation is checked for leaks or flaws. There are various tests.*The Hydrostatic test, The vessel is filled with a nearly incompressible liquid usually water or oil and examined for… …
49Hydrogen codes and standards — are codes and standards (RCS) for hydrogen fuel cell vehicles, stationary fuel cell applications and portable fuel cell applications.Codes and standards have repeatedly been identified as a major institutional barrier to deploying hydrogen… …
50Hydrogen halide — Hydrogen halides (or hydrohalic acids) are acids resulting from the chemical reaction of hydrogen with one of the halogen elements (fluorine, chlorine, bromine, iodine), which are found in Group 7 of the periodic table. Astatine is not included… …
