Advances in Chinese Carbon Capture and Storage Technology Based on Patent Information Analysis: Perspective on Technological Components

Abstract

Abstract.As an effective technical means to mitigate climate change, both innovation activities and patent protection of carbon capture and storage technology has been promoted greatly in China. The advances of the technological components of Chinese carbon capture and storage technology were investigated from several patent indicators, such as total patent number, geographical distribution of patent applications, main patent applicants and highest-value patents. It is concluded that the technological innovative capabilities of Chinese domestic applicants need to be further improved to compete with foreign applicants in the area of carbon capture and storage technology.
