Artificial photosynthesis Artificial photosynthesis Artificial photosynthesis is a chemical process that replicates the natural process of photosynthesis, a process that converts sunlight, water, and carbon dioxide into carbohydrates and oxygen; as an imitation of a natural process it is biomimetic. The term artificial photosynthesis is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel (a solar fuel). Photocatalytic water splitting converts water into hydrogen and oxygen and is a major research topic of artificial photosynthesis. Light-driven carbon dioxide reduction is another process studied that replicates natural carbon fixation. Research
Ocean storage of carbon dioxide on the dispersal to make the change in carbon dioxide concentration in the ocean low enough to not affect the marine biosphere significantly. The proposed method of injection is droplets of supercritical carbon dioxide mixed with seawater. Plumes can be engineered to dissolve at different rates based on the size, concentration, and rate of injection of the carbon dioxide/seawater droplets. For rising plumes which rely on dissolution to sequester carbon dioxide, a smaller droplet with a greater rate of injection is better because it leads to faster dissolution. Sinking plumes ideally form lakes of carbon dioxide on the ocean floor
