Japan Beyond-Brittle Project (JBBP)

Scientific drilling to demonstrate a feasibility of the engineered geothermal system in ductile zones

A new type power generation method is proposed using engineered geothermal system adequate in the volcanic zones by the nucleation of an artificial brittle fracture reservoir system completely surrounded in the ductile zones at a temperature around 500 ºC which are already confirmed such as in the Kakkonda geothermal field, northeastern Japan. The final goal of this scientific drilling project is to demonstrate the feasibility of the engineered geothermal system power generation in ductile zone with sustaining 100 % of recoverability of injected water and avoiding disastrous induced earthquakes.
