Liquid hydrogen trailer

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

History

The U-1 semi-trailer was a liquid hydrogen trailer designed in the 1950s to carry cryogenic liquid hydrogen (LH2) on roads being pulled by a powered vehicle. 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 loss rate of approximately 2 percent per day. The U-1 was a single axle semi-trailer. The specifications for its successor the U-2, a double axis 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]
