A hydrogen storage tank for a hydrogen fueled aircraft. The tank has a wall made of layers of aerogel sections around a hard shell layer, sealed within a flexible outer layer, and having the air removed to form a vacuum. The periphery of each layer section abuts other sections of that layer, but only overlies the periphery of the sections of other layers at individual points. The wall is characterized by a thermal conductivity that is lower near its gravitational top than its gravitational bottom. The tank has two exit passageways, one being direct, and the other passing through a vapor shield that extends through the wall between two layers of aerogel. A control system controls the relative flow through the two passages to regulate the boil-off rate of the tank.

A process for collection, storage and transport of boil off-gas from a liquefied natural gas storage tank. An ultra-low temperature, composite gas tank is provided to accept the boil-off gas and saturated vapor at ultra-low-temperatures in a range of about −80° C. to −45° C. (about −112° F. to −229° F.) and at high pressure of about 150 bar (about 2,175.5 psi). Boil off gas collected from liquefied natural gas storage at a pressure in a range of about 15 to 18 bar (217.5 psi to 261 psi) and at a temperature in of about −150° C. (about −238° F.). The ultra-low temperature, composite gas tank can hold the gas as it warms to ambient temperature. The process includes a liner step; a filament step; a wrap step; and a filling step. Optional steps include an insulation step; a fiber step; a layering step; a nozzle step; and a gas step.
