What Cequest Does To Capture Carbon

With Cequest, we will lower the pH of seawater via electrolysis so that CO2 is captured then combined with a dissolved mineral carbonate to form a mineral bicarbonate while also reacting a basic solution with the air, so concentrating dissolved CO2 in the ocean and removing CO2 from the atmosphere at the same time.

Mineral weathering is a method that occurs when rocks react with carbon dioxide to create mineral bicarbonates, which over time precipitate as carbonate minerals having been washed into the ocean. This is the reason behind why bicarbonate in seawater is such a huge carbon reservoir.

Electro-geo-chemistry uses saline water electrolysis by connecting two electrodes to a renewable energy source to create hydrogen fuel as well as a chemical sponge-like solution that absorbs carbon dioxide from the air and turns it into a mineral bicarbonate.

Go through the mockups below to understand how the process works in greater detail.

Key Materials We Use

In order for the reaction chamber to be assembled and for the chemical reaction to take place the following materials need to be acquired.

Seawater & Reverse Osmosis Water

Both seawater and reverse osmosis water are used in an electrolytic cation exchange module.

Nickel & Chromium Based Catalyst

A nickel and chromium-based catalyst are used, to allow widespread hydrogen production from water.

Titanium Mesh Electrodes

Platinum coated titanium mesh electrodes are resistant to oxidation and reduction have shown incredible performance in the electrolysis industry.


Cequest combines carbon dioxide with crushed limestone to form alkalized water that is returned to the sea to improve the habitat of sea creatures.
