NASA also references Safety Standard for Hydrogen and Hydrogen Systems [110] and the Sourcebook for Hydrogen Applications. [ 111 ] [ 106 ] Another organization responsible for hydrogen safety guidelines is the Compressed Gas Association (CGA) , which has a number of references of their own covering general hydrogen storage, [ 112 ] piping ...
At high concentrations, hydrogen gas is an asphyxiant, but is not otherwise toxic. [5] ISO Technical Committee 197 is developing standards governing hydrogen applications. Standards are available onboard systems, fuel tanks and vehicle refueling systems and for production (including electrolysis and steam methane reformers). [4]
Hydrogen compressors are closely related to hydrogen pumps and gas compressors: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of hydrogen gas, whereas the main result of a pump raising the pressure of a liquid is to allow the liquid hydrogen to be transported elsewhere.
Ultrahigh-pressure electrolysis is high-pressure electrolysis operating at 340–690 bars (5,000–10,000 psi). [8] At ultra-high pressures the water solubility and cross-permeation across the membrane of H 2 and O 2 is affecting hydrogen purity, modified PEMs are used to reduce cross-permeation in combination with catalytic H 2 /O 2 recombiners to maintain H 2 levels in O 2 and O 2 levels in ...
Formic acid-based fuel cells represent a promising energy supply system in terms of high volumetric energy density, theoretical energy efficiency, and theoretical open-circuit voltage. They are also able to overcome certain problems inherent to traditional hydrogen (H 2 ) feed fuel cells such as safe handling, storage, and H 2 transportation.
High-temperature electrolysis schema. Decarbonization of Economy via hydrogen produced from HTE. High-temperature electrolysis (also HTE or steam electrolysis, or HTSE) is a technology for producing hydrogen from water at high temperatures or other products, such as iron or carbon nanomaterials, as higher energy lowers needed electricity to split molecules and opens up new, potentially better ...

The National Hydrogen Energy Road Map (NHERM) is a program in India initiated by the National Hydrogen Energy Board (NHEB) in 2003 and approved in 2006 for bridging the technological gaps in different areas of hydrogen energy, including its production, storage, transportation and delivery, applications, safety, codes and standards and capacity building for the period up to 2020.
