Building the removal
Gigablue
I build ocean carbon removal at Gigablue.
Controlled carbon export at planetary scale. Permitted. Measured. Certified.
The ocean has always been the planet's largest carbon sink, pulling carbon from the surface and locking it into seafloor sediment on geological timescales. Gigablue is building a methodology to help restore that balance as emissions disrupt it.
How a pod works
Float, capture, then sink below the thermocline.
Carbon-Carrier Pods are built from non-toxic, biodegradable materials. They float so photosynthetic capture can happen, then sink autonomously, carrying that carbon below the thermocline where reduced mixing with surface water keeps it down.
Mechanism and durability as Gigablue describes them, from gigablue.co and gigablue.co/about, fetched 21 September 2026.
The gap they are aiming at
The ocean sinks about 2 Gt a year. Paris needs 7 to 9.
Both figures as stated on gigablue.co and gigablue.co/about.
