『Abstract
　Carbon capture and sequestration (CCS) can be an important technology option for China in addressing global climate change and developing clean energy technologies. Promoted by international climate conventions and supported by government research and development programs, an increasing number of CCS pilot and demonstration projects have been launched in China. In this study, we analyze the structure of China's CCS effort from a technological innovation system (TIS) perspective. Within this system, key socio-political components, including institutions, actor-networks, and technology development, are examined to evaluate the state of the innovation system. The study assessed the perceived capacity of seven functional areas of the CCS innovation system through a survey of key CCS actors and stakeholders. The findings suggest that China's CCS innovation system has a strong functional capacity for knowledge and technology development. It is significantly weaker in the innovative functions of knowledge diffusion, market formation, facilitating entrepreneurs and new entrants in to the CCS market. Based on the evaluation of China's technological innovation system to develop CCS, the article articulates specific public policies to formulate a more robust innovation system to traverse the “valley of death” from research and development to commercial deployment and accelerate energy innovation in China.
