Fluid storage tank

1. A fluid storage tank, comprising:

a plurality of tank sub-units disposed in an array wherein:

each tank sub-unit of the plurality of tank sub-units is a primary parallelohedron;

each tank sub-unit of the plurality of tank sub-units has substantially the same shape and exterior size;

the array of tank sub-units is tessellated into a three-dimensional volume;

each tank sub-unit of the plurality of tank sub-units has an aperture defined in at least one wall overlapping with an other aperture defined in at least one adjacent tank sub-unit of the plurality of tank sub-units;

each tank sub-unit of the plurality of tank sub-units is in fluid communication with a single outlet port for selectively extracting the fluid from the tank; and

each tank sub-unit of the plurality of tank sub-units is in fluid communication with a single fluid fill port.

2. The fluid storage tank as defined in claim 1 , further comprising a natural gas adsorbent disposed in each tank sub-unit of the plurality of tank sub-units in the array.

3. The fluid storage tank as defined in claim 2 wherein the natural gas adsorbent is selected from carbon, a porous polymer network, a metal organic framework, or a zeolite.

4. The fluid storage tank as defined in claim 1 wherein the single outlet port is the single fluid fill port.

5. The fluid storage tank as defined in claim 1 wherein at least two tank sub-units of the plurality of tank sub-units are in fluid communication with a manifold to add and extract the fluid from the at least two tank sub-units in parallel.

6. The fluid storage tank as defined in claim 1 wherein each tank sub-unit has an internal volume ranging from about 0.2 liter to about 3.0 liters.

7. The fluid storage tank as defined in claim 1 wherein a face of at least one tank sub-unit has a wall thickness greater than that of an other face of the at least one tank sub-unit.

8. The fluid storage tank as defined in claim 1 wherein a face of at least one tank sub-unit is formed from a material having a yield strength greater than the yield strength of an other material formed into an other face of the at least one tank sub-unit.

9. The fluid storage tank as defined in claim 1 wherein a wall thickness of a tank sub-unit having a uniform wall thickness is greater than an other wall thickness of an other tank sub-unit.

10. The fluid storage tank as defined in claim 1 , further comprising:

a first tank sub-unit formed from a first material; and

a second tank sub-unit formed from a second material wherein a yield strength of the first material is greater than a yield strength of the second material.

11. The fluid storage tank as defined in claim 1 wherein adjacent faces of adjacent tank sub-units in the array are mutually affixed and aligned with bilateral symmetry, and wherein a line through centroids of the adjacent faces is orthogonal to each of the adjacent faces of the adjacent tank sub-units.

12. The fluid storage tank as defined in claim 11 wherein the adjacent tank sub-units are welded together.

13. The fluid storage tank as defined in claim 11 wherein the adjacent tank sub-units are adhesively bonded together.

14. The fluid storage tank as defined in claim 1 wherein each tank sub-unit of the plurality of tank sub-units is a truncated octahedron.

15. The fluid storage tank as defined in claim 14 wherein the aperture is defined in a square face of the truncated octahedron.

16. The fluid storage tank as defined in claim 1 wherein each tank sub-unit of the plurality of tank sub-units is a hexagonal prism.
