摘要： An ocean iron fertilization (OIF) method and system for electrochemically controlled release of iron in an ocean to stimulate growth of phytoplankton to increase CO2 sequestration by the ocean. The system includes a cathode submerged or floating in the ocean; an iron or iron-producing anode submerged or floating in the ocean spaced apart from the cathode; and a power supply unit connected to the cathode and the anode. The power supply unit drives electric current between the cathode and the anode such the anode generates oxygen (O2) and ferrous iron through electrolysis to be released in the ocean, and the cathode produces hydrogen (H2) and hydroxide (OH—) species through an electrochemical reaction at the cathode.
