Electrochemical Process of Biorock for Carbon Dioxide Capture

The purpose of this study is to utilize information and data gathered from previous studies pertaining to the BioRock® method, patented by Dr. W. Hibertz and T.J. Goreau in 1974. Biorock® stimulates the growth of coral reefs utilizing natural reef processes and electrochemistry to remove CO2 from the atmosphere. Our aim is to make the process more efficient to achieve large scale atmospheric carbon dioxide sequestration. A pH sensor in the water and CO2 sensor is in place to quantify and confirm the reduction of CO2 in the water and air above, all within a sealed tank. The first experiment in this study used an iron mesh with an electric current running through it to collect the limestone that serves as the base for a reef. However, the iron oxidized instead of collecting limestone. Future testing will utilize a lead plate as it is less susceptible to rusting.
