| Abstract | To apply smaller-scale geothermal generation such as high temperature hot spring field about 90C, we carried out a development project of a 50 kW class Kalina cycle geothermal power generation system. From 2010, on site generation project is progressing at Matsunoyama hot spring field in Niigata Prefecture at middle of Japan. This is first test using a 50kW class Kalina system that potential is estimated as 723MW using hot spring fluid in japan without drilling. Before starting generation, we analyzed geochemistry of Takanoyu#3 test well, and surrounding well to estimate stability of production of hot spring fluid. And we estimated low scaling risk to heat exchanger from equilibrium calculation. From end of 2011, we started power generation test to estimate stability generation system and to solve several technical and law problems for promotion this business model. |
