Abstract

The technology disclosed herein relates to a system for the efficient capture and storage of carbon dioxide from a vehicle's exhaust while in transit. The system includes an apparatus for extracting the carbon dioxide from an exhaust gas and passing it to a compressor or carbon dioxide management system. The system then compresses the carbon dioxide and determines if a tire has capacity for the carbon dioxide. The tire has a carbon dioxide chamber and an external air chamber. If the carbon dioxide air chamber has capacity, the compressor will supply compressed carbon dioxide into the carbon dioxide chamber. Upon arrival at an external storage location, the carbon dioxide stored in the tires are able to be extracted and supplied to the external storage location.

First claim

What is claimed is:

1. A system onboard a vehicle to facilitate storage of carbon dioxide extracted from the vehicle in transit, the system comprising:
a wheel assembly coupled to a tire, wherein the wheel assembly comprises a first compartment and the wheel assembly coupled to the tire forms a second compartment; and
a hub assembly configured to provide rotational energy to the wheel assembly, wherein the hub assembly comprises (1) a supply line configured to receive the carbon dioxide and (2) a spindle air passage coupled to the supply line, the spindle air passage comprises air passage bearings to allow the carbon dioxide to pass from a first side of the hub assembly to a second side of the hub assembly to an inlet line system to inflate the first compartment with the carbon dioxide, the second compartment comprises a volume of air, and the second compartment is coupled to a pressure release value configured to release air from the second compartment when the second compartment satisfies a threshold pressure.

2. The system of claim 1 , wherein the carbon dioxide is captured from an exhaust gas emitted from an engine associated with the vehicle.

3. The system of claim 1 , further comprising a carbon dioxide compressor, wherein the carbon dioxide compressor is operated using one or more processors.

4. The system of claim 3 , wherein the one or more processors are linked to one or more sensors that detect pressure and flow to the first compartment from the carbon dioxide compressor.

5. The system of claim 4 , wherein the one or more processors are configured to determine, using a detected flow and a detected pressure, a volume within the first compartment is below a threshold.

6. The system of claim 5 , wherein the one or more processors are configured to turn the carbon dioxide compressor on based on determining that the volume is below the threshold.

7. The system of claim 1 , wherein the tire has a first pressure and a first volume, the first volume being a combination of a first compartment volume and a second compartment volume.

8. A method comprising:
determining that a first chamber of a wheel assembly coupled to a tire has a first capacity to accept carbon dioxide;
determining that a second chamber formed from the wheel assembly coupled to the tire has a second capacity to discharge air contained in the second chamber;
based at least in part on determining that the first chamber has the first capacity to accept the carbon dioxide, supplying the carbon dioxide at a first pressure to the first chamber via a hub assembly comprising (1) a supply line configured to receive the carbon dioxide and (2) a spindle air passage coupled to the supply line, wherein the spindle air passage comprises air passage bearings to allow the carbon dioxide to pass from a first side of the hub assembly to a second side of the hub assembly to an inlet line system to inflate the first chamber with the carbon dioxide until the first chamber does not have the first capacity; and
allowing the air contained within the second chamber to be released until the first chamber is at a full capacity.

9. The method of claim 8 , wherein the first chamber is determined to have the first capacity based at least in part an available volume of the first chamber.

10. The method of claim 9 , wherein the first chamber is further determined to have the first capacity based in part on a measured flow and a measured pressure of the carbon dioxide within the first chamber.

11. The method of claim 10 , wherein the measured flow is determined by a flow valve located between a compressor and the tire.

12. The method of claim 8 , wherein the carbon dioxide is provided by a carbon sequestration system that captures the carbon dioxide from an engine exhaust system.

13. The method of claim 8 , further comprising: removing the carbon dioxide from the first chamber by pressurizing the second chamber and opening a release valve connected to the first chamber.

14. The method of claim 8 , wherein the tire has and a first volume, the first volume being a combination of a first chamber volume and a second chamber volume.

15. One or more non-transitory computer storage media having computer-executable instructions embodied thereon, that when executed by at least one processor, cause the at least one processor to perform operations comprising:
determining that a first chamber of a wheel assembly coupled to a tire has a first capacity to accept carbon dioxide;
determining that a second chamber formed from the wheel assembly coupled to the tire has a second capacity to discharge air contained in the second chamber;
based at least in part on determining that the first chamber has the first capacity to accept the carbon dioxide, supplying the carbon dioxide at a first pressure to the first chamber via a hub assembly comprising (1) a supply line configured to receive the carbon dioxide and (2) a spindle air passage coupled to the supply line, wherein the spindle air passage comprises air passage bearings to allow the carbon dioxide to pass from a first side of the hub assembly to a second side of the hub assembly to an inlet line system to inflate the first chamber with the carbon dioxide until the first chamber does not have the first capacity, wherein the carbon dioxide is provided by a carbon sequestration system that captures the carbon dioxide from an engine exhaust system; and
allowing the air contained within the second chamber to be released until the first chamber is at a full capacity.

16. The one or more non-transitory computer storage media of claim 15 , wherein the first chamber is determined to have the first capacity based at least in part an available volume of the first chamber.

17. The one or more non-transitory computer storage media of claim 16 , wherein the first chamber is further determined to have the first capacity based in part on a measured flow and a measured pressure of the carbon dioxide within the first chamber.

18. The one or more non-transitory computer storage media of claim 17 , wherein the measured flow is determined by a flow valve located between a compressor and the tire.

19. The one or more non-transitory computer storage media of claim 15 , further comprising: removing the carbon dioxide from the first chamber by pressurizing the second chamber and opening a release valve connected to the first chamber.
