Recent Membrane Developments for CO2 Separation and Capture

Increasing concerns on global warming and climate change have led to numerous attempts and advanced technology developments to tackle the problem of excessive greenhouse gases emitted to the atmosphere. One of the technical strategies receiving great attention is the application of membrane technology for greenhouse gas separation/capture. Such technology exhibits significant advantages over other conventional methods in terms of removal efficiency, compactness, and environmental friendliness. Many state-of-the-art membrane developments as well as its applications to post-combustion treatment, which could be a promising approach for reducing CO2 emission from point sources, are thoroughly reviewed. Furthermore, a comprehensive survey on the future perspective of membrane technologies as a potential solution for CO2 removal and utilization is provided.
