Hydrogen tube trailers are semi-trailers that consist of 4 to 36 cluster high-pressure hydrogen tanks varying in length from 20feet for small tubes to 53feet on jumbo tube trailers. They are part of the hydrogen highway[1] and usually precede a local hydrogen station.
Older tube trailers made of steel (Type I) usually carry about per load, while new and more efficient composite trailers (Type IV) made of carbon fiber make it possible to carry up to 1t per load. Modular tube trailers range from 8 to 54 tubes.[2]
Intermediate tubes are assembled in banks of 5 tubes in lengths of 19and and provide mobile or stationary storage.[3]
A trailer with 10 tubes and a 442NaN2 chassis, operating with pressures in excess of 3200psi.[4]
As of 2012, the US Department of Transportation (DOT) started to award Special Permits (SP) to different manufactures to produce Type IV Hydrogen trailers in the US. The US is the current leader in Composite tank manufacturing.
