Our Story Began

more than one billion years ago, when macroalgae emerged as a hearty carbon sequestering, oxygen producing scavenger of the sea. It went on to be so successful that it is now a common ancestor of all land-based plants. 

Our solar-powered vessel can sink macroalgae
in the deep sea for effective carbon sequestration.


Our first step is to embark on the removal of invasive
Sargassum macroalgae in the Caribbean region.

We’ll do this by deploying a fleet of vessels to gather and sink the macroalgae to depths greater than 1000 meters for durable ocean sequestration of more than 100 years.

Through the process of photosynthesis, Sargassum captures CO2 from the air and water. Since it has a one year lifespan and regional currents typically deliver it to shorelines within a few weeks, its most likely fate is to get washed up on shore and decompose, producing a large amount of methane and re-releasing CO2.

Gathering and sinking Sargassum not only provides a carbon removal opportunity, but numerous co-benefits to Caribbean communities and ecosystems that are harmed by the collective anthropogenic changes to the earth that contribute to the Sargassum invasion.
