Vehicle Tire CO2 Storage for Mobile Carbon Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle carbon dioxide capture and storage systems face challenges with efficient storage, as they require large and heavy storage tanks or high energy usage for liquefaction and compression, which reduces fuel efficiency and increases costs.
Innovation Solution
A system that captures carbon dioxide from a vehicle's exhaust and stores it in the vehicle's tires, using a carbon dioxide capture apparatus and a compressor linked to the tires through transfer lines, allowing for efficient storage by displacing air in the tire compartments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large storage tanks are used to store captured carbon dioxide on the vehicle, then the storage capacity is improved, but the vehicle weight increases
Solution Approach 1:
The patent applies multi-functionality by using existing vehicle tires for dual purposes: maintaining vehicle inflation pressure and storing captured carbon dioxide. The tires serve as both functional components for vehicle operation and as storage vessels for CO2, eliminating the need for separate dedicated storage tanks and reducing overall vehicle weight while maintaining storage capacity
2Quantity of substance
If carbon dioxide is liquefied and compressed for storage, then the storage density is improved, but the energy consumption increases
Solution Approach 1:
The patent applies parameter changes by storing carbon dioxide in a gaseous state at elevated pressures (typically 30-50 psi above tire pressure) rather than liquefying it. This approach achieves sufficient storage density for mobile applications without the high energy consumption associated with liquefaction processes, optimizing the pressure parameter to balance storage efficiency and energy usage
3Quantity of substance
If heavy storage tanks are installed on the vehicle, then the carbon dioxide storage capacity is improved, but the fuel efficiency deteriorates
Solution Approach 1:
The patent eliminates heavy dedicated storage tanks by repurposing existing vehicle tires as storage vessels. This multi-functional approach maintains adequate CO2 storage capacity while significantly reducing vehicle weight, thereby improving fuel efficiency without sacrificing storage capability
4Quantity of substance
If air is removed from tire compartments for carbon dioxide storage, then the carbon dioxide storage capacity is improved, but the tire inflation pressure control becomes complex
Solution Approach 1:
The patent applies self-service by using the vehicle's existing air compressor and pressure regulation systems to manage both tire inflation and carbon dioxide storage. The system automatically maintains proper tire pressure by adding or removing gas as needed, eliminating the need for complex dedicated pressure control mechanisms while enabling CO2 storage in the tire compartments

AI summary
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.
