Coal dominated energy resources and consumption dominate the energy structure in China. This leads to the great challenges for China’s future energy development along with both growing demand for energy and high pressure for CO2 emissions reduction. From the earlier viewpoint, the reduction of CO2 emission could be reached by replacing fossil fuel by low-carbon energy resources for electricity generation. However, it gave rise to the questions. Is it possible to directly using low-carbon energy on the reduction of CO2 emission? Is there an efficient way to decrease the emission of CO2 by low-carbon energy, and utilize the C and O in CO2 to produce useful materials? Thus, a potential scheme is proposed to couple coal with the low-carbon energy via the high efficient integration, including nuclear, wind, solar, biomass and hydro power etc. Such a hybrid energy system may target both CO2 reduction and recycle on a large-scale.
