These are things we hope to quantify through our experiment which would be done in an isolated, simulated-seawater environment in order to avoid any such risks and allow for regular sampling to monitor the reaction products.

Electrolytic Mineral Accretion for CO2 Sequestration

In some informal discussions, Thomas Goreau talks about how its possible that under the generation of brucite, due to high pH at the cathode, the main reactions would be: Mg++ + 2OH- = Mg(OH)2 Ca++ + CO3-- = CaCO3 OH- + HCO3- = CO3-- + H2O 2H2O + 2Cl- = H2 + Cl2 + 2OH- instead of H2O + Cl- = 2H+ + Cl- + ClO- There is some belief that under these conditions, chlorine is oxidized to provide the hydroxide ions rather than the oxidation of water. Assuming this is the case, the emission of CO2 from the interactions of H+ normally generated from the ionization of water could be essentially neglected. While this is the theory, there could be unmeasured kinetic inhibitions that prevent this.

Hi Paul! There is some discussion that theorizes that by selectively producing brucite, the generation of hydrogen ions responsible for carbon emission can be limited and the overall process becomes carbon negative. To my knowledge, there is little to no exploration into this and so my aim is to determine the validity of these theories.
