The Deep Ocean Is Earth's Carbon Vault. We Built the Key
MCFS is the only ocean carbon removal method engineered for full containment, controlled descent, and independent verification from the surface to the seafloor.

OUR PROCESS
How it Works
01 — COMPOSITION
Our Carbon-Carrier Pods are engineered structures containing a nutrient-infused cellulose substrate that enables photosynthetic carbon capture entirely within the pod.
02 — TRANSIT
Once deposited at the ocean’s surface, the Carbon-Carriers Pods travel through the photic zone fixing CO2 inside the enclosed structure before descending to the deep ocean intact. Carbon is exported as a contained unit and remains sequestered in the deep ocean sediment for centuries.
03 — OUTCOME
The net result is durable, verifiable carbon removal engineered to work with the ocean's natural carbon cycle, not disrupt it. No land required. No uncontrolled biological response. Just controlled descent, measurable export, and independent verification at every stage.

Engineered. Deployed. Sequestered
Carbon-Carrier Pods are biodegradable, non-toxic particles manufactured at CETI in Leilé, France on one of the lowest-carbon electricity grids in the world. Micronutrients are bound within the fibre matrix as stable, non-dispersing oxides that are insoluble in seawater.
Once in the ocean, the Carbon-Carrier Pods capture carbon within a contained environment, drawing down atmospheric CO₂ through photosynthesis. After approximately 18 days floating at the surface, the pods rapidly sink, carrying the captured carbon to the deep ocean.
Within months of reaching depth, the Carbon-Carrier Pods biodegrade due to their cellulose composition. This ensures that the carbon exported to depth remains sequestered in deep ocean sediment for centuries while the carrier itself leaves no trace.

Unlike Ocean Fertilization (OF), MCFS does not add iron, other nutrients, or any chemical inputs directly into the surface ocean. MCFS binds stable micronutrient oxides inside the Carbon-Carrier Pods to create a targeted and controlled environment for microalgae cultivation before sinking to depth. Similar to Biomass Sinking (BMS), in MCFS there is no biological manipulation or bloom risk, only controlled carbon fixation and export.
MCFS does not add iron, nutrients, or any chemical stimulants to ocean water. OIF works by accelerating phytoplankton growth; Carbon-Carrier Pods are passive physical objects that sink under gravity. There is no biological manipulation, no bloom risk, and no analogous regulatory concern.

No Double-Counting Risk
Credits are issued only after verifying each sequestration event, with unique serial numbers registered on Puro.earth's public registry.
Durable Claims
Gigablue's Carbon-Carrier Pods are designed to transport carbon to depths where the ocean itself can hold it for 1000+ years.
Regulatory Alignment
Methodology was developed with input from ICES and ISO scientific advisors, ensuring compatibility with emerging marine carbon governance frameworks.
