A team of researchers has developed a system that produces electricity and hydrogen while eliminating carbon dioxide (CO2), which is the main contributor to global warming.
The team from the Ulsan National Institute of Science and Technology in South Korea created a “Hybrid Na-CO2” system that can continuously produce electrical energy and hydrogen through efficient CO2 conversion, with a stable operation for over 1,000 hours without any damage to electrodes.
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 the water to induce an electrochemical reaction.
If acidity increases, the number of protons increases, which in turn increases the power to attract electrons.
