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 water column. The carbon dioxide is usually injected at 1000 m depth to reduce carbon dioxide bubble escape. As injected carbon dioxide bubbles rise, dispersal increases up the water column. Large dispersal areas and low concentrations of carbon dioxide significantly decrease any significant changes in local pH and resulting effects on marine ecosystems. Wickett et al. used measurements in natural pH fluctuations from atmospheric carbon dioxide to suggest that dilute carbon dioxide injection at 0.37 GTC/ yr would have a negligible effect on ocean pH. Dilute ocean injection requires little infrastructure in comparison to other forms of ocean injection. The
