Carbon capture and storage (CCS) is a process that involves capturing carbon dioxide (CO2) emissions from power plants and other industrial sources, and storing them underground in geological formations such as depleted oil and gas reservoirs or saline aquifers. The goal of CCS is to reduce the amount of CO2 being released into the atmosphere, which is a major contributor to climate change. CCS is considered an important part of the broader strategy to combat global warming and transition to a low-carbon economy.
