Ocean Visions Selects Launchpad Teams
- Captura Captura is developing electrochemical approaches and scalable technologies to extract CO2 directly from seawater for sequestration purposes. Captura’s offshore platform system will use a novel electrodialysis unit to split and separate water molecules into acid and base, enabling the capture of high-purity CO2 gas and helping restore the pH balance of seawater. The only system inputs would be oceanwater and sunlight.
- Ebb Carbon Ebb Carbon is pioneering a new approach to ocean-based carbon removal. Their proprietary electrochemical system uses low carbon electricity to separate salt water into acid and base, enhancing the ocean’s natural ability to safely store excess atmospheric carbon dioxide, while reducing ocean acidity. Sensors and software control how much base is returned to the ocean, to verify the amount of CO2 removed.
- Phykos Phykos will grow seaweed to capture carbon from the surface layer of the ocean. They plan on using robotic vessels that will navigate to optimal conditions to grow seaweed. Autonomous and mechanized platforms will allow for periodic harvesting, whereby sheared seaweed would be sunk to the deep ocean—taking with it embodied carbon.
- Running Tide Running Tide is deploying and testing free-floating microforests in the open ocean to sequester carbon before sinking into the deep ocean for durable storage. A proprietary system will remotely monitor these microforests, quantifying kelp growth, carbon content, and sinking locations.
- Seafields Seafields plans to harness the power of the floating seaweed Sargassum to capture and store carbon at scale. Offshore sustainable aqua-farms, irrigated by pipes that bring nutrient-rich waters to the surface, will support the cultivation of Sargassum, which will then be harvested. Carbon-rich leftovers would then be baled, compressed, and sunk to the bottom of the ocean to lock away carbon.
- TROFX TROFX is currently demonstrating offshore structures for macroalgae cultivation and nutrient upwelling, while developing proprietary technology for the extraction of valuable protein components. The team aims to demonstrate rugged and low capital cost infrastructure capable of producing massive quantities of biomass, and an efficient system for precisely transporting macroalgae into the deep ocean for sequestration.
