Researchers Turn Carbon Emissions Into Usable Energy

A team of researchers has developed a system that produces electricity and hydrogen eliminating carbon dioxide (CO2), which is the main contributor to global warming.

The team of the Ulsan National Institute of Science and Technology in South Korea created a "hybrid no-CO2" system, continuously through efficient CO2 conversion, with the stable operation for more than 1,000 hours without any loss of electrodes. Can produce electrical energy and hydrogen.

Guntae Kim, professor of the School of Energy and Chemical Engineering at UNIST, said, "The key to that technique is the simple conversion of chemically stable CO2 molecules to other materials. Our new system solved this problem with CO2 dissolution mechanism. is."

Most emission of human CO2 is absorbed by the ocean and turns into acidity.

The researchers focused on this phenomenon and came up with the idea of melting CO2 to water to inspire an electrochemical reaction.

If acidity increases, then the number of protons increases, which in turn increases the power to attract electrons.

If a battery system is built on the basis of this phenomenon, then electricity can be produced by removing CO2.

With the "Hybrid Na-CO2" system, the conversion capacity of CO2 is more than 50 percent at this time.

"This hybrid NO-CO2 cell uses not only CO2 as a resource to generate electricity, but also produces clean energy source, hydrogen," Jeongwon Kim published a letter from UNIST Was published in iScience Magazine.
