1. A cryo-compression vessel comprising:
an insulation layer; and
a composite overwrapped pressure vessel (COPV) encapsulated within the insulation layer and at least partially separated from the insulation layer by an interstitial gas chamber, the COPV comprising:
a liner comprising a cylinder with a pair of ellipsoidal end caps formed as a unitary body from a metal alloy, the metal alloy comprising: greater than 92.0% aluminum by mass, greater than 2.0% copper by mass, greater than 0.2% manganese by mass, and less than 0.6% magnesium by mass; and
a composite overwrap structure encapsulating the metal liner,
wherein the COPV houses cryo-compressed hydrogen at a pressure above 100 bar and at a cryogenic temperature.
