The past two decades have seen dramatic growth in research and application of CO2 capture methods and subsequent chemical, biological and geological sequestration. Absorption using amine solutions is the most mature CO2 capture method and the only one in large scale industrial applications. Research interest in adsorption continues to grow, with the related annual publication volume surpassing that of absorption recently. The four types of industrial settings for capturing CO2 from power plant (post-combustion, pre-combustion, oxy-fuel combustion and chemical looping combustion) have been briefly discussed and the corresponding publication trends studied.
