Coal dominated energy resource and consumption 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 emission reduction.
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.
The carbon flow for hybrid energy system is based on the utilization of carbon resources and the process of carbon recycling. High-carbon energy resources such as coal could be coupled with low-carbon energy resources such as nuclear energy and renewable energies by the effective integration between substances, energy and information.
Nuclear-assisted coal-based energy system and wind/solar-assisted coal (biomass)-based systems are analyzed as the case study for the preliminary techno-economic evaluations with detailed explanations provided. Such an integration is revealed to produce energy and chemicals with a simultaneous increase in both energy and carbon efficiency of fossil fuel. Hence, the low-carbon hybrid energy system can be considered as the potential solution to China's future energy development.
Obviously, the low-carbon hybrid energy system has the advantages of both high-carbon resources (such as coal) and low-carbon energy resources (such as nuclear or renewable energy) for the production of liquid fuel and chemicals on a large scale. It focuses on the current energy situation in China, fits the direction of energy development in China, and provides the strategic solution to China's future energy.
