Project Innovation + Advantages:
Fearless Fund will lead a MARINER Category 1 project to design and develop a new system to enable large-scale macroalgae “ranching” using remote sensing, imaging, and modeling technologies. The core concept targets monitoring free-floating, low-impact Sargassum seaweed in the Gulf of Mexico for cost-effective biomass harvest. Fearless Fund’s cultivation process is designed to mimic naturally occurring seaweed mats found at the surface of the ocean. The concept leverages the free-floating nature of Sargassum, reducing costs from labor, seeding, and harvesting normally associated with seaweed farming. Fearless Fund will investigate the potential to artificially “seed” circular currents found in the Gulf of Mexico with Sargassum cuttings. The team envisions that Sargassum could be ranched within Gulf currents, where it can grow to maturity at a predicted rate. The circular current transports the crop closer to shore at the projected time of harvest, which is calculated based on historical data. Remote sensing technologies will be used to monitor the crop over a three month cultivation season before harvesting the new crop with barges and tug boats after the uninterrupted initial growing period. By improving these methods and leveraging the wealth of data generated from a suite of sensors, the team hopes that industrial-scale farming of macroalgae can be achieved without capital-intensive infrastructure.
