Cryogenic Containment System

Abstract:

A cryogenic fluid containment system is disclosed. The system can store a fluid such as hydrogen at a cryogenic temperature and pressure. As the fluid naturally warms, the fluid can be directed to a portion of a liquefaction system that is configured to perform a cooling technique on the fluid. The cooling techniques may be Joule-Thomson cooling techniques. The liquefaction system may be equipped to perform both non-Joule-Thomson cooling techniques and Joule-Thomson cooling techniques. The system is configured to direct fluid to an appropriate portion of the liquefaction system, which may be based at least in part upon a Joule-Thomson coefficient of the fluid.
