Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing atmospheric CO2 levels, such as carbon capture and storage, are insufficient to meet the targets set by the Paris Agreement, and there is a need for new measures to effectively store carbon over long periods.
Innovation Solution
The method involves dividing organic material into small particles, preparing a pumpable slurry with water, and pumping this slurry into a bog or bogland, where it is stored without decomposition, effectively sequestering carbon over a long time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If organic material is placed in a bog for long-term carbon storage, then CO2 sequestration is achieved, but the bog level decreases causing drying out and reduced farming capability
Solution Approach 1:
The patent uses hydraulic principles by pumping water together with organic material slurry through pipes into the bog. This simultaneous water injection compensates for the level decrease caused by material placement, maintaining bog moisture and preventing drying out while achieving carbon storage
2Quantity of substance
If organic material is placed directly into a bog, then carbon storage is achieved, but the material cannot be transported efficiently over long distances
Solution Approach 1:
The patent converts organic material into a pumpable slurry form by mixing with water, enabling efficient transportation through pipes over long distances. The slurry can be pumped directly from production sites to bogs, eliminating the need for complex handling of solid organic material
Solution Approach 2:
The patent changes the physical state of organic material from solid to liquid slurry form by adjusting concentration and mixing with water. This parameter change makes the material fluid and pumpable, enabling easy transport while maintaining the organic carbon content for storage
3Quantity of substance
If more organic material is placed in a bog to increase carbon storage, then CO2 reduction is improved, but the bog structure may be damaged and conservation capabilities reduced
Solution Approach 1:
The patent uses controlled slurry injection through pipes to distribute organic material evenly throughout the bog without causing structural damage. The simultaneous water injection maintains proper bog density and structure, preventing compaction and preserving conservation capabilities
Solution Approach 2:
The patent implements monitoring of bog conditions during and after material placement, with feedback control to adjust the process and prevent damage to bog structure and conservation capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for the long-term storage of CO2 in the form of naturally bound carbon, raising the level of bogs to support farming without drying them out, and maintaining the bog's conservation capabilities, thereby contributing significantly to reducing atmospheric CO2 levels.
Implementation Method 1
mixing the organic material with water to form a pumpable mixture/slurry
Implementation Method 2
pumping the mixture/slurry into a bog or bogland through one or more pipes
Implementation Method 3
Anaerobic and sterile conditions in the bog mean that nothing rots therein
