We partner with the ocean to rebalance the carbon cycle and move fast carbon back to slow.

The atmosphere and upper ocean are key components of the fast carbon cycle. CO₂ is constantly moving between the atmosphere and the ocean's surface.
The ocean's biological carbon pump is the world's most powerful carbon removal technology that moves 2 billion tons of carbon from the fast to slow cycle every year.
One recipe in our system is to distribute small carbon buoys made from fast carbon rich forestry residue and limestone, and seeded with algae into the open ocean. Hundreds of miles offshore.
With only ocean currents, sunlight, and gravity and a helping hand from ocean chemistry we move carbon from the fast cycle to the slow.
As our carbon buoys float, the limestone slowly dissolves, restoring ocean alkalinity, combatting ocean acidification, and moving fast carbon to slow. Sort of like a tums for the ocean.
The buoys seeded with algae fix fast carbon through photosynthesis. After less than 3 months the buoy and algae lose buoyancy and sink rapidly.
…and sink...
Quickly reaching the deep ocean, 1000's of meters down where it is put under immense pressure from gravity. Gravity is our friend.
The carbon embodied in the buoy and algae will either be buried in ocean sediments or consumed by deep-sea marine life.
Like the 38,000 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.

Precoess kelp underwater – Running Tide

Running Tide moves carbon from the fast to the slow carbon cycle to restore ocean health.


Carbon buoys move fast to the slow carbon cycle through ocean alkalinity restoration and photosynthesis before sinking to the deep ocean in a matter of months.


The ocean is ⅔ of Earth’s surface. Our carbon buoys are deployed in locations far from shore where it doesn’t compete for land or coastal space. With the potential of moving gigatons of carbon per year.


The deep ocean is a key part of the slow carbon cycle that can lock carbon away for hundreds to millions of years.


The natural simplicity of our multi-pathway system creates massive supply chain efficiencies and scale.
