Abstract: This paper introduces the development of carbon capture and storage (CCS) technology, the progresses in CCS demonstration projects, and the international regulations and policies related to CCS technology. Barriers for the large-scale deployment and application of CCS are discussed, and different technological solutions for emission reduction are compared (e.g. energy conservation and renewable energy). The analysis shows that, on the one hand, the negative impacts of CCS deployment should be carefully evaluated, and on the other hand, the research and development (R&D) input of key CCS techniques also need to be enhanced in order to grasp core technologies in the CCS system. Furthermore, CCS incentives should depend on actual CCS development. At last, based on current situation, we need to focus on the development of existing thermal power plants which retrofit with CCS technology, so it can do more help to future large-scale promotion of CCS.

Key words: carbon capture and storage (CCS), research and development (R&D), climate change, energy saving and emission reduction
