Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbine power generation system with enhanced cooling by a carbon dioxide stream (46) from a carbon dioxide source (44) and to cool hot gas path components using the carbon dioxide stream (46). SOLUTION: This turbine power generating system includes a compressor (12), a combustor (66), a turbine (14), a generator (16), and a shaft (20), wherein the shaft (20) is integrally connected to the compressor (12), the turbine (14), and the generator (16) such that mechanical energy produced from the turbine (14) is used to drive the compressor (12) and the generator (16). Carbon dioxide that is sequestered from exhaust (26) of the turbine (14) may be stored and injected back into the turbine to cool the hot gas path components of the turbine (14).
