Summary:

Integrating carbon capture and storage (CCS) with fossil energy is a significant and essential part of a clean energy portfolio to combat global warming and climate change. The International Energy Agency (IEA), CCS indicates CCS can contribute approximately one-fifth of the greenhouse gas reductions GHG) emissions needed to limit atmospheric temperature rises to < 2 degrees Celsius. Currently, over 70 large-scale CCS projects are in various stages of development around the world. The Global CCS Institute’s primary role is to catalyze the acceleration of broad CCS deployment through fact-based advocacy and knowledge sharing. This is a critical role, since many challenges still exist for CCS. The reality, however, is that CCS technology works. The individual technologies comprising the CCS system are not new, having been around for decades. CCS technology is currently still expensive, with most of the cost falling within the capture process, due to added equipment and energy penalty. However, CCS costs are within the range of other clean technologies and competitive on a non-subsidized basis. CCS R&D needs to be, and is currently being continued on two fronts: capture cost and energy penalty reduction; and ensuring safe, effective long term geologic storage.
