Efficient storage and transport of cryogenic fluids are of prime importance because of the relatively high cost of liquid production. Vessels for holding liquid hydrogen and helium are always carefully insulated, usually with an insulation which includes vacuum. Less stringent requirements apply to vessels for nitrogen and oxygen. However, the same general rules and techniques apply to the insulation of any cryogenic device. The heat transport to the container holding the cryogenic fluid arises from conduction through mechanical supports and from heat transport across the insulation space.
