A cryogenic tank support assembly and method are provided. In one embodiment, a cryogenic tank support assembly includes an outer tank structure, an inner tank structure having a storage volume therein for storing a cryogenic material, one or more keys on an outer side of the inner tank structure, and one or more key blocks comprised of a thermally insulating material and affixed to an inner side of the outer tank structure to define one or more keyways. Each of the one or more keys may be configured to be received in a corresponding one of the one or more keyways. When the key(s) is/are received in the keyway(s), the key block(s) contact the key(s) to support the inner tank structure in a spaced relation with the outer tank structure such that the inner tank structure does not directly contact the outer tank structure.
