Discussion on Carbon Dioxide as an Energy Source
Energy sources in the world often use various things as sources, but whether carbon dioxide can be used as energy is also studied by the academic community.

Energy sources can be used to generate energy. Traditional energy sources, such as coal, oil, and natural gas, all contain carbon, which can be burned and released. Although carbon dioxide also contains carbon, its properties are stable and different from traditional energy sources. To make it an energy source, it is necessary to explore ways to transform its properties.

Or, chemical methods can be used to make carbon dioxide and other things react to produce energetic properties. For example, a special catalyst can be used to guide carbon dioxide and hydrogen to react, and organic compounds such as methanol can be produced. Methanol is flammable and can be an energy donor. This process needs to be able to drive it away. If the energy taken is renewable energy, such as electricity converted from solar and wind energy, so that the reaction can be carried out, then carbon dioxide can gradually become one of the energy sources.

And also, researchers are also thinking about biological methods. In the biological world, there are photosynthetic organisms that can borrow light energy, use carbon dioxide and water as materials, and raw sugars and other energy storage qualities. If this mechanism can be modeled, artificial photosynthetic systems can turn carbon dioxide into energy storage properties, and it is also expected to turn carbon dioxide into energy.

There are still many obstacles to making carbon dioxide a usable energy source. First, the efficiency of the reaction is not high, whether it is chemical catalysis or simulated biological photosynthesis, the rate of conversion is not enough to meet the needs of the world. Second, the cost is quite huge, and the research and development of related equipment is expensive and laborious, making it difficult to apply on a large scale.

Despite the difficulties, the researcher has not abandoned it. Because carbon dioxide is the first greenhouse gas, if it can be converted into energy, it will not only solve the energy problem, but also slow down the greenhouse effect, which is of double benefit. Therefore, researchers are trying to explore new methods, seek efficient catalysts, and build exquisite photosynthetic systems, in the hope that carbon dioxide can be used as a reliable energy source in the future, so as to save the world's energy and protect the earth's environment.
