Trial on spatial evaluation of feasibility of geothermal power generation based on geoscience information in Japan

Abstract

This paper describes a resource evaluation method by evaluating the amount of geoscientific information such as hydrothermal alteration zone, where the potential amount of geothermal power generation is connected to actual power generation to reduce the misfit with a practical exploration result. We created simple estimation formula based on the Multiple Regression model of the capacity of the power plant using both hydrothermal alteration zones and hot springs. A relatively good estimation was obtained by using 18 power plants, and an example map of the potential amount of power generation in the Sengan area is shown. The proposed method indicates agreement with existing potential maps and advantages such as spatial distribution so further improvement of the performance and usefulness of this approach is worth considering.
