The energy demand and environmental impacts of oxy-fuel combustion vs. post-combustion capture in China

Oxy-fuel combustion is one of the clean coal combustion technologies for CO2 capture. However, post-combustion capture is studied as a challenged technology against oxy-fuel combustion. This paper presented the life cycle assessment (LCA) of these two CO2 capture technologies used in the 300 MW coal...
