Asphyxiant gas

An asphyxiant gas is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air.

Compressed hydrogen tube trailer

Hydrogen tube trailers are semi-trailers that consist of 10 to 36 cluster high-pressure hydrogen tanks varying in length from for small tubes to on jumbo tube trailers.

Cryo-adsorption

Cryo-adsorption is a method used for hydrogen storage where gaseous hydrogen at cryogenic temperatures (150—60 K) is physically adsorbed on porous material, mostly activated carbon.

Pressure

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Slush hydrogen

Slush hydrogen is a combination of liquid hydrogen and solid hydrogen at the triple point with a lower temperature and a higher density than liquid hydrogen.

Standard cubic foot

A standard cubic foot (scf) is a unit used both in the natural gas industry to represent an amount of natural gas and in other industries where other gases are used.
