Abstract
A non-cylindrical pressure vessel storage tank is disclosed. The storage tank includes an internal structure. The internal structure is coupled to at least one wall of the storage tank. The internal structure shapes and internally supports the storage tank. The pressure vessel storage tank has a conformability of about 0.8 to about 1.0. The internal structure can be, but is not limited to, a Schwarz-P structure, an egg-crate shaped structure, or carbon fiber ligament structure.
Claims14
A non-cylindrical pressure vessel storage tank comprising:
- a. an internal structure, coupled to an inner surface of at least one wall of the storage tank, to shape and internally support the storage tank;
- and
- b. a conformability in a range of about 0.8 to 1.0;
- wherein the internal structure is a Schwarz-P structured shape capped as an internal reinforcement lattice.
A non-cylindrical pressure vessel storage tank comprising:
- a. an internal structure, coupled to an inner surface of at least one wall of the storage tank, to shape and internally support the storage tank;
- and
- b. a conformability in a range of about 0.8 to 1.0,
- wherein the storage tank is rated for a pressure of approximately 25 MPa and is independent of contents, with a gravimetric efficiency of approximately 1 L/kg (stored volume divided by tank mass) or greater and a volumetric efficiency of approximately 4.6 L(storage)/L(material) or greater.
