What is Carbon Capture and Storage (CCS)?
Geological storage is a four-step process: • first, a pure or nearly pure stream of CO2 is captured from flue gas or other process stream; • next it is compressed to about 100 atmospheres; • it is then transported by pipeline to the injection site; • and finally, it is injected deep underground into a geological formation such as an oil and gas reservoir where it can be safely stored for thousands of years or longer.
