How it Works


reducing carbon emissions isn’t enough. We also need to scrub existing Co2

How it works 

Building a mid-ocean aquafarm to grow the floating seaweed Sargassum fluitans and natans at scale in a controlled and sustainable way. We will harvest and extract valuable product. Then bale, compress and sink the carbon rich leftovers, permanently removing the carbon from the atmosphere. Working in areas where Sargassum grows naturally, we are deploying eminent scientist at the cutting edge of natural, ocean-based carbon sequestering projects, to develop and test technologies to achieve our objective: to remove 1Gt of CO2 from the atmosphere each year.



Seafields aims to remove 1Gt of CO2 from the atmosphere each year using floating Sargassum. We will develop and test off-shore technologies to aquafarm, harvest, process, bale and sink Sargassum to substainably and efficiently manage this seaweed for long-term safe and natural carbon sequestration. In addition, we will provide Sargassum year-round to industry, to produce products that substitute fossil fuels such as biofertilizers, bioplastics and biofuels. This will contribute to carbon dioxide emissions reductions globally.
