There is a great need for a sustainable fossil fuel power system with near zero CO2 emissions and stabilizing the renewable electricity. Setting a course towards such sustainability and stabilization will require the development of energy sources that do not emit carbon dioxide to the atmosphere in the coming decades. Here, we investigated the possible hybrid power generation from solar and carbon fuels, in which CO2 has been captured by solar thermochemical process. The evaluation of the potential of this hybrid energy system could contribute to a development that can allow both free of carbon dioxide emissions and stabilization of solar electricity.
