The geoengineering process of carbon capture and storage involves isolating CO2 from fossil fuel power stations in pre or post-combustion processes, compressing the CO2 until it forms a liquid, transporting the liquid CO2, often through pipelines, and then pumping it deep underground into porous rock layers that can safely hold it for long periods of time (Please see the Minerals Council of Australia’s YouTube video below “How does Carbon Capture and Storage work?”).
