The cryogenic fluid tank is configured to store a cryogenic fluid within the cryogenic fluid tank and the first and second LNG pipe are in fluid communication with to the cryogenic fluid tank. The first LNG pipe is in fluid communication with compressor.

A novel tank cryogenic-compatible composite pressure vessel that beneficially utilizes Vapor Cooled Shielding (VCS) is introduced to minimize thermal gradients along support structures and reduces heat loads on cryogenic systems. In particular, the configurations and mechanisms to be utilized herein include: providing for a desired number of passageways and a given thickness of the VCS, reducing the thermal conductivity of the VCS material, and increasing the cooling capacitance of the hydrogen vapors.

A portable cryogenic container includes a porous material configured to absorb a cryogenic coolant such as liquid nitrogen. The coolant-absorbing material at least partially defines a storage cavity in the container that is configured to accept and support a cassette or other type of contents container in which a product to be cryogenically stored is contained. With cryogenic coolant absorbed into the container, the temperature within the storage cavity can be maintained sufficiently close to the boiling point of the cryogenic coolant to preserve post-thaw viability of the stored product for several hours.
