CCS involves three main steps: capturing CO2, transporting it, and storing it securely underground. Capture technologies can be applied to power plants and industrial processes to separate CO2 from other emissions. The captured CO2 is then transported, often via pipelines, to a storage site where it is injected into geological formations such as depleted oil and gas fields or deep saline aquifers. The integrity of these storage sites is vital to prevent potential leaks that could pose environmental toxicology concerns.
