CRYOPUMPING-RESISTANT LH2 STORAGE VESSEL
The present disclosure provides liquid gas storage containers and methods thereof. The liquid gas storage container includes an inner shell forming a cavity. The inner shell is disposed on an insulation base. The insulation base includes an insulation sub-layer. The liquid gas storage container includes an outer shell forming an insulation volume between the inner shell and the outer shell. A first insulation layer is disposed within the insulation volume and around the inner shell and the insulation base. A second insulation layer is disposed within the insulation volume between the first insulation layer and the outer shell.
1 . A liquid gas storage container comprising:
an inner shell forming a cavity, the inner shell disposed on an insulation base, the insulation base comprising a first insulation sub-layer;
an outer shell forming an insulation volume between the inner shell and the outer shell;
a first insulation layer disposed within the insulation volume and around the inner shell and the insulation base; and
a second insulation layer disposed within the insulation volume between the first insulation layer and the outer shell.
2 . The liquid gas storage container of claim 1 , further comprising a skirt disposed along a sidewall of the insulation base.
3 . The liquid gas storage container of claim 2 , wherein the first insulation layer is disposed within the insulation volume and around the skirt.
4 . The liquid gas storage container of claim 3 , further comprising one or more anchors mechanically coupled to the skirt.
5 . The liquid gas storage container of claim 1 , wherein the first insulation sub-layer comprises a pressure of about 100 mTorr to about 1000 mTorr.
6 . The liquid gas storage container of claim 1 , wherein the first insulation sub-layer comprises a load-bearing insulation.
7 . The liquid gas storage container of claim 6 , wherein the first insulation sub-layer comprises a load-bearing foam comprising a closed-cell foam.
8 . The liquid gas storage container of claim 1 , further comprising an interleaving layer disposed between:
the first insulation sub-layer and a second insulation sub-layer; or
the first insulation layer and the second insulation layer.
9 . The liquid gas storage container of claim 1 , further comprising a protective layer disposed on the first insulation sub-layer.
10 . The liquid gas storage container of claim 1 , wherein the second insulation layer comprises a bulk fill material.
11 . The liquid gas storage container of claim 10 , wherein the bulk fill material comprises one or more of perlite, glass microspheres, fiberglass, or a mixture thereof.
