Detailed explanation-1: -A group of scientists from Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed Hybrid Na-CO2 system that, they claim, is capable of producing electricity and hydrogen from carbon dioxide (CO2) dissolved in aqueous solution.
Detailed explanation-2: -Most SAF is made out of carbon from organic vegetable oils, but Twelve, a chemical technology company based in Berkeley, California, is making fuel out of carbon dioxide.
Detailed explanation-3: -Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
Detailed explanation-4: -When CO2 is injected into the aqueous electrolyte, it reacts with the cathode, turning the solution more acidic, which in turn generates electricity and creates hydrogen.
Detailed explanation-5: -Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide (CO₂) underground and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.
