The invention discloses a semi-closed supercritical carbon dioxide Brayton cycle zero-carbon-emission hybrid power system combusting hydrocarbon fuel, which comprises a semi-closed supercritical carbon dioxide Brayton cycle system used for converting energy generated by fuel combustion into mechanical work and driving an electric power system to generate electricity through the mechanical work, part of the residual waste heat converted into the mechanical work is conveyed to an organic Rankine cycle waste heat recovery system; the organic Rankine cycle waste heat recovery system is used for recycling waste heat conveyed by the semi-closed supercritical CO2 Brayton cycle system and converting the waste heat into mechanical work, and the power system is driven to generate power through the mechanical work; the electric power system is used for achieving conversion between mechanical work and electric energy, storing the electric energy and providing driving force for land transportation tools. According to the invention, CO2 generated by combustion is completely captured and stored in the CO2 storage tank, NOx pollutants are not generated by pure oxygen combustion, only condensed water is discharged to the outside, and the system has the advantages of zero carbon emission and zero pollutant emission.
