A fuel tank in a vehicle. The fuel tank includes a protective outer shell, an inner shell and a crush sleeve. The protective outer shell defines an outer tank. The inner shell defines an inner tank which holds fuel. The inner shell is housed in the outer shell and is isolated from the outer shell by a space. The crush sleeve is provided in the space between the outer shell and the inner shell. The crush sleeve supports the inner shell and maintains the inner shell in position relative to the outer shell. Wherein during an impact to the vehicle, the force of the impact causes the outer shell and the crush sleeve to deform and the inner shell to move relative to the outer shell.

A shipping container for shipping thermally active materials includes a plurality of structural panels that define a container interior, and are configured for receiving the thermally active materials. The container also includes an exterior disposed adjacent to an environment in which the shipping container is disposed. A thermal barrier member is placeable between the thermally active materials and the environment in which the container is placed. The thermal barrier includes a thermal barrier interior panel and a thermal barrier external panel defining a heat absorbing material receiving cavity. A flowable polymer based heat absorbing material is disposed within the heat absorbing material receiving cavity. The thermal barrier is configured to substantially surround the thermally active materials to reduce the passage of thermal energy between the thermally active materials and the environment in which the shipping container is disposed.

A compartment for storing an energy source in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds the energy source, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.
