Running Tide is an aquaculture company that harnesses the power of the ocean to capture and sequester CO2. Specifically, Running Tide grows kelp to sequester carbon and sink it deep into the ocean.
Kelp is a powerful CO₂ storage system with its ability to grow many times faster than trees. Kelp forests can store up to 20 times more carbon per acre than land forests.
Running Tide plans to attach kelp to a biodegradable buoy with a timer. After six to nine months, the timer pops the buoy, flooding it with water and sinking it to the ocean’s depths. It is estimated that kelp sunk 1,000 metres deep will store CO₂ for at least 1,000 years.
