Revolutionizing carbon sequestration with Nature’s own Blueprint

The Problem

  • Every year, humanity emits over 40 gigatons (billions of tons) of Carbon dioxide, accelerating climate change, and its extreme effects. Climate modeling has been happening since the 1970’s and we have never under projected our emissions.

  • Climate tech is advancing, but not fast enough. Current solutions are failing by three metrics:

    1. Cost - Current solutions like Direct Air Capture (DAC) cost $600-$1000/ton, making large-scale deployment unrealistic.

    2. Scale - Many solutions target thousands of tons per year, which isn’t enough. The largest DAC plant removes only 30 seconds’ worth of global emissions per year.

    3. Efficiency - Using a ton of energy to remove carbon defies basic physics. We don’t need giant factories—we need nature to do the work for us.

  • The math doesn’t add up. Current carbon removal methods are too expensive, too slow, and too inefficient to meet global targets. If we want real impact, we need solutions that are efficiently scalable, cost-effective, and permanent.

    That’s exactly what we’re building.

The Solution

  • The Coupler

    Our patent-pending method centers around the FloCS Coupler, a specialized substrate designed to optimize co-settlement of macroalgae (floaters) and calcifying organisms (sinkers). By embedding the right chemical and structural settlement cues, we enhance natural attachment, growth, and longevity of both organisms. Additionally, the coupler is infused with micronutrients to boosting carbon capture efficiency.

  • Final Product

    The end product of a fully developed FloCS unit. We can scale to produce billions of larval units, which develop into hundreds of thousands of these final FloCS systems, creating a self-sustaining carbon sequestration process that sinks completely naturally.

  • The Sinker

    The sinker ensures deep ocean carbon storage by acting as a natural weight, sinking macroalgae beyond the thermocline (~1,000 meters) into sediments to avoid remineralization. At specific depths its shell dissolves, it buffers acidification (just like a tums!).

    Each individual sinker can produce millions of larvae.

  • The Floater

    The floater uses pneumatocysts (air-filled bladders) to stay buoyant while photosynthesizing and storing carbon in its biomass. As the sinker pulls it down, the pneumatocysts collapse or implode, ensuring permanent sinking.

    Each floater can produce billions of spores.

Our Pilot: Sargassum

  • What is Sargassum?

    Sargassum is a floating macroalgae—technically a protist—fueled by iron-rich dust from Africa’s west coast, forming vast mats in the Sargasso Sea. Since 2011, massive blooms have exploded, overwhelming the Caribbean, Gulf of Mexico, and Atlantic coasts, disrupting ecosystems, harming tourism, and releasing toxic gases. While often blamed on nutrient pollution, the real driver is climate change—sargassum thrives under rising CO₂ levels, turning it into a growing environmental and public health crisis.

  • Sargassum's Costly Toll on Tourism

    Each year, waves of rotting sargassum wash ashore, disrupting peak tourism seasons. The foul odor and harmful gases drive away guests, leading to cancellations, bad reviews, and lost revenue. Coastal businesses struggle, threatening local economies that rely on tourism. Without action, this recurring crisis will only get worse.

  • Sargassum's Hidden Health Crisis

    As rotting sargassum breaks down, it releases hydrogen sulfide and ammonia, polluting coastal air (rotten egg smell). Studies link exposure to an increased risk of preeclampsia in pregnant women, while workers and residents suffer from respiratory issues and mental health struggles. Children in nearby schools report headaches and difficulty focusing, and those who swim in it risk skin rashes and irritation. This growing public health crisis demands urgent action.

  • Harming Ecosystems

    Massive sargassum blooms smother coral reefs, blocking sunlight and releasing harmful chemicals that destroy marine ecosystems. When it washes ashore, it traps baby sea turtles, preventing them from reaching the ocean. Left unchecked, sargassum threatens the very life that depends on these fragile coastal habitats.

  • Sargassum Strangles Local Fisheries

    While fishermen rely on sargassum rafts in the open ocean to attract fish, these same blooms become a major obstacle when they reach the shore. Thick sargassum blocks boats from launching, clogs engines, and disrupts nearshore fisheries, leaving local fishermen unable to work and provide for their communities.

  • The Costly Burden of Cleanup

    Hotels and resorts spend millions on manual sargassum removal, yet the problem keeps returning. Cleanup is labor-intensive, harmful to beaches, and disrupts operations, driving up costs while deterring tourists. A sustainable solution is needed—one that reduces cleanup expenses, restores coastal beauty, and protects local economies from this ongoing crisis.

A Cleaner Caribbean Starts With You

Sargassum is threatening the beaches you love, the communities that depend on them, and the marine life that makes them unique. But you can make a difference.
