Calcium carbonate, or limestone, is the basic compound of coral reefs and other marine organisms such as mollusks.
Mineral Accretion Technology (“MAT”), is a process of electrolytic deposition of calcium carbonate from seawater and has a multitude of applications:
The principles of MAT are simple and consist of passing a low-voltage direct electrical current through an anode to a cathode, to induce electrolysis.
The electrical field causes a chemical reaction that allows calcium carbonate to form using dissolved minerals from the seawater. This calcium carbonate then either settles on the metal structure (the cathode) or is used by corals and mollusks to help them grow.
The power requirements of MAT are very low, which makes the system very cost effective and gives it a very low total carbon footprint. The voltage required is only 6 volts and only 1 ampere is required per square meter of expose metal area (1A/m^2).
