Scientists from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed a system that can produce electricity and hydrogen fuel from carbon dioxide. The Hybrid Na-CO2 system can continuously produce electrical energy and hydrogen through efficient carbon dioxide (CO2) conversion with stable operation for over 1,000 hours. The key to this technology is the easy conversion of chemically stable CO2 molecules to other materials. Much of human CO2 emissions are absorbed by the ocean and turned into acidity. The researchers focused on this phenomenon and came up with the idea of melting CO2 into water to induce an electrochemical reaction.If acidity increases, the number of protons increases, which in turn increases the power to attract electrons. If a battery system is created based on this phenomenon, electricity can be produced by removing CO2. In particular, this system has shown stability to the point of operating for more than 1,000 hours without damage to electrodes. The system can be applied to remove CO2 by inducing voluntary chemical reactions.
