Our vision for the future


Harvesting and baling Sargassum in the Atlantic to sequester gigatons of carbon

Make a serious dent in past emissions

Creating products that replace fossil fuels helps reduce current emissions, but by baling Sargassum and then sinking these bales to the deep ocean, we can achieve a scale that could allow us to make a serious dent in past emissions as well. We intend to sink our first bales in 2021, testing these theories rigorously and monitoring the effects on the environment.


Harvesting & baling floating Sargassum

Seafields will develop proprietary underwater pipes to upwell nutrients that will feed the Sargassum we’ll grow in the mid-Atlantic, ready for processing and baling for multiple different uses.

Carbon sequestering of unavoidable and past emissions

We will process the Sargassum, extracting the valuable products, bale the remaining carbon rich leftovers and sink it to the bottom of the ocean, recreating the process that created our planet’s oil and coal in the first place, just considerably faster this time. We will sell via offset credits in the voluntary carbon market.

Wholesale to industry

We will also supply partners with thousands of tonnes of raw Sargassum, for them to refine to use as alternatives to plastic, building materials, furniture filler, rubber and even cosmetics.

Food scarcity & job creation

We can help to solve food scarcity against a growing global population. Our Sargassum farms will be in the South Atlantic gyres, the equivalent of the Sahara Desert in the ocean. Very little lives and grows there so we’re not interrupting existing ecosystems. We expect huge industries to spring up around our aquafarms, providing food sources that don’t rely on depleting terrestrial resources, and creating significant employment opportunities.


A new agricultural revolution

If we achieve at-scale mid ocean harvesting of Sargassum, we can bring about the third agricultural revolution, moving our society away from being ocean hunter-gatherers to being ocean farmers. Knowing what we now know about the need for sustainable agriculture, we can do this in a balanced way, leveraging the ocean’s deserts to provide new food sources and taking the pressure off coastal habitats.
