A team of researchers has developed a system that produces electricity and hydrogen while eliminating carbon dioxide (CO2), which is the main contributor of 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 stable operation for over 1,000 hour 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 water to induce an electrochemical reaction.
“This hybrid Na-CO2 cell not only utilises CO2 as the resource for generating electrical energy but also produces the clean energy source, hydrogen,” said Jeongwon Kim from UNIST in a paper published in the journal iScience. (IANS)
