Scientists have discovered a revolutionary technology, a way to attract CO2 from the atmosphere and turn it into charcoal. This new discovery has the potential to change the way we think CO2.

The research, recently published in the journal Nature Communications, provides a step by step guide for filming CO2 coal, acting to remove greenhouse gases from the atmosphere and imprison them as solid carbon.

Carbon sequestration, which consists of removing carbon dioxide from the atmosphere and enclosing it, is a rapidly expanding area that aims to mitigate the effects of climate change. Large oil and gas companies, such as shell, spend billions of dollars to develop carbon sequestration facilities that store CO2 in porous reservoirs in the Earth. However, this approach is expensive because it requires CO2 be compressed in liquid form and injected into rock formations of the Earth. Because of the costs, this approach is not economically viable without significant subsidies and / or a carbon tax to help offset costs.

This recent development adds another method for effectively trapping carbon dioxide in a safe and long-term manner. This is not the first time that scientists convert carbon dioxide into a solid form. However, the previous techniques required extremely high temperatures, making the approach impractical beyond a laboratory.

Convert CO2 the researchers used a liquid metal catalyst containing cerium to turn coal into solid carbon into a solid coal, which is particularly effective in driving electricity and has specific properties.

When the researchers electrically charged a ship with CO2 and the liquid metal, the carbon dioxide began to turn into small flakes of coal. The solid carbon flakes are naturally detached from the liquid metal and fall to the bottom of the container, thus allowing the continuous production of solid carbon from carbon dioxide. The final product may also contain an electrical charge, which means that it could be used as a supercapacitor after the process.

Carbon sequestration, which consists of removing carbon dioxide from the atmosphere and converting it to a liquid or solid, presents an attractive approach to mitigating climate change. While humans continue to emit carbon dioxide into the atmosphere, an inexpensive and large-scale method CO2 of the atmosphere would provide an ideal solution.

The international research team from Germany, China, the United States and Australia believes this is a first step towards an abundant and inexpensive method of removing carbon dioxide from the environment. atmosphere and recycle it as solid coal.
