Floating Apparatus Buoyancy Loss for Marine Carbon Sequestration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cultivating marine species like microalgae, macroalgae, and crustaceans for carbon sequestration and bioremediation are often labor-intensive and inefficient, requiring extensive tending and longlines, which are costly and not scalable for large-scale carbon capture.
Innovation Solution
A floating apparatus designed to cultivate and accumulate target marine species, featuring a buoyant member that loses buoyancy over time, allowing the species to sink and sequester carbon, with optional sensing and communication modules for monitoring growth and carbon sequestration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional longline methods are used for cultivating marine species, then the target product can be accumulated, but the system becomes labor-intensive and inefficient
Solution Approach 1:
The floating apparatus is designed to automatically cultivate marine species without requiring continuous human intervention. The system self-regulates by allowing natural growth processes to occur on the floating structure, eliminating the need for manual tending that characterizes traditional longline methods.
Solution Approach 2:
The cultivation system is divided into modular floating apparatus units that can be independently deployed and managed. Each apparatus serves as a self-contained cultivation module, improving overall system efficiency by allowing parallel operation of multiple units rather than managing extensive continuous longlines.
2Productivity
If traditional cultivation methods are used, then marine species can be accumulated, but the system becomes expensive and not scalable
Solution Approach 1:
The floating apparatus serves multiple functions: it provides a platform for marine species cultivation, acts as a floating structure that naturally distributes organisms, and enables carbon sequestration monitoring. This multi-functionality reduces the need for separate systems and reduces overall complexity and cost compared to traditional specialized equipment.
Solution Approach 2:
The system changes the fundamental parameter of cultivation location from fixed longlines to mobile floating apparatus, enabling scalable deployment across different water bodies. This parameter change allows the system to be expanded by simply adding more floating units rather than extending complex longline infrastructure.
3Productivity
If marine species are cultivated on the surface, then growth is efficient, but carbon sequestration is reduced
Solution Approach 1:
The floating apparatus dynamically transitions from a floating state during the growth phase to a sinking state for carbon sequestration. This dynamic behavior allows the system to optimize for growth rate when floating at the surface and then effectively sequester carbon when sunk to the seafloor, resolving the contradiction between these two objectives.
Solution Approach 2:
The system employs periodic action by alternating between growth phases (floating at surface) and sequestration phases (sunk to bottom). This periodic cycling allows marine species to accumulate biomass efficiently during floating periods and then transfer that biomass to sequester carbon during sinking periods, achieving both high productivity and reliable carbon capture.

AI summary
Systems and methods for cultivating or accumulating climate-focused marine target products are described herein. The target product may be microalgae, macroalgae, plankton, marine bacteria or archaea, filter feeders (such as oysters or clams), or crustaceans either for the purpose of bioremediation, eventual cultivation or for sequestering carbon dioxide; or the target product may be direct chemical or biological accumulation of carbon or carbon containing organisms. The system is primarily a floating apparatus designed to hold the target product in a region of the water column and in a spatial region of the water where it will best accumulate target product mass. In some embodiments the system is designed to achieve eventual passive sinking (transformation from a floating to sinking apparatus) into the deep ocean. In some embodiments, the system is equipped with purpose-chosen sensors to instrument and quantify the various biological and mechanical processes occurring onboard.
