We capture CO₂ using kelp microforests, then sink the carbon into the deep ocean.

CO₂ is constantly moving between the atmosphere and the ocean's surface.
The ocean absorbs more CO₂ than it releases. It fixes a massive amount of CO₂ as carbon through photosynthesis in surface waters and transports it to the deep ocean where it is durably stored.
Running Tides microforests are  distributed carbon buoys that utilize macroalgae such as kelp to amplify the natural carbon sink of the ocean.
Kelp microforests are our planets most effective carbon removal system using only ocean currents, sunlight, and gravity.
As our microforests float the kelp grows and absorbs CO₂.
In a matter of months, growth will peak and the microforest sinks.
…and sinks...
Eventually the microforest reaches the deep ocean where it is put under immense pressure from gravity.
The carbon embodied in the microforest will either be buried in sediments or consumed by deep-sea marine life
Like the 37,000 gigatons of carbon already stored in deep ocean reservoirs, this carbon is removed from the fast carbon cycle for hundreds - up to millions - of years.

Running Tide microforests remove carbon with the sun, ocean currents and gravity.


Macroalgae grows fast. In less than 1 year our microforests remove and durably store carbon. There is no waiting for long term growth.


The ocean is ⅔ of Earth’s surface. Our microforests grow in locations far from shore where it doesn’t compete for land or coastal space.


The deep ocean is a natural carbon store that can lock carbon away for up to millions of years.

The natural simplicity of this system allows for massive price reductions.
