Ocean-Based CO₂ Extraction
A modular, low-cost, distributed approach to ocean-based CO₂ extraction that can scale globally to combat climate change.
Our solution consists of small, self-contained electrochemical extraction units that can be attached to existing marine infrastructure or deployed as free-floating devices. This technical design document outlines our approach to creating a viable ocean carbon dioxide removal (CDR) solution that minimizes cost, complexity, and environmental impact while maximizing scalability and carbon capture efficiency.
Innovative Technology
Utilizing a novel electrochemical approach based on bismuth-silver electrodes that extract CO₂ with minimal energy requirements. The process works by creating a local pH swing that releases CO₂ from seawater while returning alkalinized water to the ocean.

Each unit is designed to cost approximately $100 at scale, with projected carbon removal costs around $65-100 per ton of CO₂. This represents a significant improvement over many existing carbon capture technologies.
Learn moreHighly Scalable
The modular design allows for distributed deployment on existing marine vessels, structures, or as independent buoys. With millions of potential deployment points globally, this approach can scale to gigaton-level carbon removal.
Learn moreProject Overview
This document presents a comprehensive technical design for small-scale, modular ocean-based CO₂ extraction devices. These units utilize an electrochemical process to capture CO₂ from seawater, which has approximately 150x the concentration of CO₂ compared to air, making the extraction significantly more efficient.
Each unit is self-contained with power generation, extraction mechanism, and communications.
The design emphasizes low materials cost, energy efficiency, and durability in marine environments.
Units can be deployed on boats, buoys, piers, or any marine structure with access to sunlight and seawater.
The networked design allows for real-time monitoring, optimization, and verification of carbon capture.
Why Ocean-Based Carbon Capture?
The ocean naturally contains about 50 times more CO₂ than the atmosphere and absorbs approximately 25% of annual anthropogenic CO₂ emissions. By extracting CO₂ from seawater and properly sequestering it, we can leverage this natural carbon sink while simultaneously reducing ocean acidification.
Our approach offers significant advantages over direct air capture (DAC), including lower energy requirements, higher efficiency, and the ability to deploy units globally using existing maritime infrastructure.
