Composite LH2 Cryogenic Tanks: Boil-Off Control, Permeation Barriers and Space-Grade Insulation
Liquid hydrogen offers unmatched gravimetric energy density, but storing it at −253°C makes every gram of heat and every molecule of gas matter. A composite LH2 tank has a carbon fiber overwrap for structural strength and a polymer liner for gas containment, yet neither layer alone deci
