CO2 sequestration, also known as carbon capture and storage, is a process of capturing carbon dioxide (CO2) emissions from sources such as power plants and industrial facilities and storing them in geological formations underground or in the ocean, in order to prevent them from being released into the atmosphere and contributing to global warming. The goal of CO2 sequestration is to reduce the amount of CO2 that is released into the atmosphere, thereby mitigating the effects of climate change. Research in this area focuses on developing technologies and methods for capturing and storing CO2 emissions effectively and safely.
