PROBLEM TO BE SOLVED: To generate electric power at a high recovery rate of heat transmission medium and high power generation efficiency, and enable fixation and storage of carbon dioxide in a stratum layer in high temperature rock power generation. SOLUTION: This system includes an injection well 1a and a production well 1b excavated in a high temperature rock ground, a high pressure pump injecting water as heat transmission medium into the injection well 1a, a gas compressor 4 injecting gas 10 containing carbon dioxide as heat transmission medium into the injection well 1a, a separator separating heat transmission medium heated by heat of the high temperature rock ground and collected from the production well into hot water and steam, and a generator 6 generating electric power with using steam separated by the separator 5. Hot water separated by the separator 5 injected again to the high temperature rock ground from the injection well 1a. COPYRIGHT: (C)2009,JPO&INPIT
