| A CO 2 -capturing hybrid-type power generation system with highly ecient use of solar thermal energy was proposed and its characteristics were investigated. In the system, relatively low temperature saturated steam is produced using solar thermal energy and is used as the working uid of a methane-ring gas-turbine system. The solar thermal utilization eciency becomes considerably high compared with that of conventional solar thermal power plants in which superheated steam near 670 K is used as the working uid of steam turbines. The proposed system is a hybrid-type energy system in which the generated CO 2 is recovered based on combusting oxygen, and thus a highly ecient system without emissions of CO 2 and NO x can be expected to be constructed even in regions with poor solar insolation. The characteristics of the system with 10,000 m 2 collector area were estimated based on a computer simulation model. It has been estimated through simulation study that the net generated power ... | |||||||||||||||
