gaseous state
Gas is one of the four fundamental state of matter, states of matter (the others being solid, liquid, and plasma (physics), plasma).
A pure gas may be made up of individual atoms (e.g. a noble gas like neon), chemical element, elemental molec ...

hydrogen storage in
hydrogen vehicle
A hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as ships and aircraft. Power is generated by converting the chemical energy of hydrogen to mechanical energ ...

Infrastructure
Compressed hydrogen is used in hydrogen pipeline transport and in compressed hydrogen tube trailer
Hydrogen tube trailers are semi-trailers that consist of 4 to 36 cluster high-pressure hydrogen tanks varying in length from for small tubes to on jumbo tube trailers. They are part of the hydrogen highway and usually precede a local hydrogen st ...
