![]() ![]() CO 2 is captured from stationary emissions sources such as power stations, natural gas production, fossil fuel hydrogen production and industrial facilities such as steel or cement manufacturing plants. Together with Questacon, the National Science and Technology Centre in Canberra, we used a specialised camera that allows us to image CO 2 to record some basic experiments and everyday uses of CO 2.Ĭapture. ![]() We can observe the behaviour of CO 2 in various situations (for example, releasing CO 2 bubbles from opening a soft drink can), which helps us to understand how CO 2 will behave in geological formations. Natural CO 2 accumulations in the subsurface and natural gas fields provide good examples of how CO 2 can be permanently trapped underground. ![]() CO 2 can be captured and injected deep underground for permanent storage. CO 2 is a greenhouse gas that occurs naturally and is also emitted as a result of human activities such as burning fossil fuels, agriculture, and other industries (this is called anthropogenic CO 2, that is, CO 2 emitted as a result of human activity). Typically, depths of storage are around 2 km underground.ĬO 2. Carbon capture and storage (CCS), sometimes referred to as carbon capture, utilisation and storage (CCUS), takes carbon dioxide (CO 2) captured from the burning of fossil fuels and other sources (such as from cement production, steel manufacture), and injects it deep underground into the tiny pore spaces present between grains in sedimentary rocks (such as sandstones). ![]()
