Chemical Looping Combustion

Chemical Looping Combustion is an innovative method to burn fuel while capturing carbon dioxide (CO₂). It uses specialized metal particles, called oxygen carriers, to transfer oxygen from air to the fuel in separate reactors. When the metal reacts with the fuel, it produces energy and a metal oxide. In a subsequent step, the metal oxide is re-energized by exposure to air, releasing CO₂ in a concentrated form. This process avoids mixing CO₂ with nitrogen from the air, making it easier to capture and store the CO₂, which helps reduce greenhouse gas emissions from power plants.
