Liquid hydrogen requires such low temperatures that leaks may solidify other air components such as nitrogen and oxygen. Solid oxygen can mix with liquid hydrogen, forming a mixture that could self-ignite. A jet fire can also ignite. [4] At high concentrations, hydrogen gas is an asphyxiant, but is not otherwise toxic.

Liquid hydrogen also has a much higher specific energy than gasoline, natural gas, or diesel. [12] The density of liquid hydrogen is only 70.85 kg/m 3 (at 20 K), a relative density of just 0.07. Although the specific energy is more than twice that of other fuels, this gives it a remarkably low volumetric energy density, many fold lower.
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...
A hydrogen tanker or liquid hydrogen tanker is a tank ship designed ... Further research on maritime transport of hydrogen was done in the development for safe ...
For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. The overarching challenge is the very low boiling point of H 2 : it boils around 20.268 K (−252.882 °C or −423.188 °F).
A liquid hydrogen tank car, also called liquid hydrogen tank wagon or liquid hydrogen tanker wagon is a railroad tank car designed to carry cryogenic liquid hydrogen (LH 2). LH 2 tank cars with a capacity of 17,000 pounds (7,711 kg) are used for transcontinental transport. [1] [2]
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 ...
