A **liquid-hydrogen trailer** is a [trailer](/source/Semi-trailer) designed to carry [cryogenic](/source/Cryogenic) [liquid hydrogen](/source/Liquid_hydrogen) (LH2) on roads being [pulled](/source/Towing) by a [powered vehicle](/source/Tractor_unit). The largest such vehicles are similar to [railroad](/source/Railroad) [tanktainers](/source/Tank_container) which are also designed to carry liquefied loads. Liquid-hydrogen trailers tend to be large; they are [insulated](/source/Thermal_insulation). Some are [semi-trailers](/source/Semi-trailer).[1]

## History

The [U-1 semi-trailer](/source/U-1_(semi-trailer)) was a liquid-hydrogen trailer designed in the 1950s to carry [cryogenic](/source/Cryogenic) [liquid hydrogen](/source/Liquid_hydrogen) (LH2) on roads being [pulled](/source/Towing) by a [powered vehicle](/source/Tractor_unit). It was constructed by the Cambridge Corporation and had a capacity of 26,000 liters (6,900 U.S. gal; 5,700 imp gal) with a [hydrogen](/source/Hydrogen) loss rate of approximately 2 percent per day. The U-1 was a single-[axle](/source/Axle) [semi-trailer](/source/Semi-trailer). The specifications for its successor the U-2, a double axle semi-trailer, were issued on 15 March 1957.[2]

## Size and volume

Liquid hydrogen trailers are referenced by their size or volume capacity. Liquid-hydrogen trailers typically have capacities ranging from 28,400 to 49,200 liters (7,502 to 12,997 U.S. gal; 6,247 to 10,822 imp gal) gross volume.[3][4]
