OCEAN REMOVAL

This concept imitates the natural carbon capture process in shell and rock formation to remove dissolved CO from Earth’s oceans2

1 SEAWATER INTAKE

Seawater is drawn into the device through a mesh, creating an electrical charge in the water.

2 2 CHEMICAL CHANGES

The electrical charge that’s induced as the water passes through the mesh causes the dissolved CO2 to combine with calcium and magnesium in the water.

3 DEPLETED SEAWATER

As the water passes through the system, its CO content is reduced.

4 DEPOSITS

In a similar way to the formation of shells, the CO2, magnesium and calcium become limestone and magnesite when combined. These are deposited as solids.

5 RETURN TO OCEAN

After passing through the device, the water is depleted of dissolved CO2. This space can be filled with more CO2, removing more from the atmosphere.
