Myth: Carbon capture and storage is not a feasible way to reduce human CO2 emissions
Reality: With the right technologies and know-how, successful CCS will allow a viable industry that will reduce the human contribution to atmospheric CO2 levels.
Carbon capture and storage (CCS) is the separation and capture of carbon dioxide (CO2) from the emissions of industrial processes and storing it in deep underground geologic formations. CCS enables industries to continue to operate while emitting fewer greenhouse gases (CHGs), making it a powerful tool for addressing mitigation of anthropogenic CO2 in the atmosphere.
However, storage must be safe, environmentally sustainable, and cost-effective. Suitable storage formations can occur in both onshore and offshore settings, and each type of geologic formation presents different opportunities and challenges. Geologic storage is defined as the placement of CO2 into a subsurface formation so that it will remain safely and permanently stored. There are five types of underground formations for geologic carbon storage:
- Saline formations
- Oil and natural gas reservoirs
- Unmineable coal seams
- Organic-rich shales
- Basalt formations
