Performance analysis of a near zero CO2 emission solar hybrid power generation system

•A novel solar hybrid power system with near zero CO2 emission has been proposed.•The system integrates fuel reforming, solar-driven steam generation and CO2 capture.•Solar heat upgrading and high-efficiency heat-to-power conversion are achieved.•The system accomplishes near zero CO2 emission with oxy-fuel combustion.•The system thermodynamic performances have been investigated and compared.
