Solution Overview
Problem
Current technologies for reducing carbon dioxide emissions from combustion engines and fuel cells are either expensive, complex, or limited by energy density and recharging time, and existing methods fail to achieve emission-free operation effectively.
Innovation Solution
A device and method that utilize the oxidation of carbonaceous fuels to produce exhaust gases consisting of carbon dioxide and water, which are then compressed, condensed, and stored, using oxygen-enriched air or pure oxygen as an oxidant, and integrated into a closed cycle for thermo-chemical or electro-chemical energy conversion, allowing for efficient capture and recycling of carbon dioxide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If carbon dioxide is captured in amine-based solvents for large-scale industrial application, then carbon dioxide emissions are reduced, but the system becomes expensive and complicated
Solution Approach 1:
The patent extracts carbon dioxide from combustion exhaust gases using a membrane separation system, isolating the harmful component for compression and storage while allowing other exhaust components to be treated separately or released
Solution Approach 2:
The patent introduces a membrane as an intermediary separation medium that selectively allows carbon dioxide to pass through while blocking other gases, enabling efficient capture without complex chemical solvent systems
2Object-generated harmful factors
If battery systems are used for electrically operated vehicles, then emissions are eliminated, but energy density is too small and recharging time is excessive
Solution Approach 1:
The patent changes the energy storage parameter from chemical batteries to compressed carbon dioxide gas storage, achieving higher energy density and faster refueling times while maintaining zero emissions through the closed-loop system
Solution Approach 2:
The patent implements a periodic cycle where carbon dioxide is captured during combustion, compressed and stored, then periodically released and converted back to fuel, creating a continuous zero-emission operation rhythm
3Object-generated harmful factors
If hydrogen is used as fuel for internal combustion engines or fuel cells, then carbon dioxide emissions are avoided, but energy density is lower than hydrocarbon fuels and production and storage problems arise
Solution Approach 1:
The patent creates a self-service system where the vehicle's own combustion process produces carbon dioxide that is then captured, compressed, and converted back to fuel, eliminating the need for external hydrogen production and storage infrastructure
Solution Approach 2:
The patent recovers carbon dioxide that would otherwise be discarded as exhaust emission, compressing and storing it for subsequent fuel synthesis, transforming a waste product into a valuable resource
