Sucking up CO2
HQ: Portland, ME
Kelp-farming carbon-sinking robots.
Oceans represent two-thirds of the Earth’s surface and are the main theater of war for climate change, even more than forests. From acidification to pollution to temperature rise, human activity has altered the ocean’s chemistry in ways that may not be undone even if we slash CO2 emissions from land-based sources. Reversing these impacts at scale requires technology that accelerates the ocean’s organic rejuvenation.
How it Works
Running Tide uses robotics to drive the highest throughput aquaculture farms in the world. They pre-grow kelp or shellfish “seeds” in hatcheries where they can carefully calibrate salinity, temperatures, and other factors that determine taste and growth. Seeds are then transferred to automated ocean farms for the final growth stages. The result is premium shellfish at a fraction of the cost, time, and space.
In automating shellfish farming, Running Tide produces a sustainable, premium, and carbon-negative protein source as cheaply as chicken nuggets but with a vastly healthier nutrition profile. The hatcheries and robotic fleet also serve other forms of aquaculture, like kelp production. The unavoidable by-products are restoration of marine habitats and large-scale carbon removal.
