The process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (usually in underground geological formations) for centuries or millennia. It is a key technology for mitigating climate change.
Enhanced Oil Recovery using CO2 dates back to the 1970s, but the focus on CCS for climate mitigation has grown significantly in the 21st century.
Carbon capture projects are being developed globally, with applications in heavy industry (cement, steel) and power generation.
