Japan: Geothermal Power System Uses Injected River Water

New geothermal power generator set for trial run (NHK)

A Japanese venture firm and researchers at a university in Japan say they have developed a new system that harnesses geothermal power. They say a trial run of the system will start later this week.

Tokyo-based Japan New Energy and Kyoto University jointly created the technology.

Members of the project team say it does not require the usual process of pumping up hot springs or underground steam. The new generator uses river water that's sent into pipes deep underground where it's heated, then brought back up to the surface to generate electricity.

The officials say the trial run will start in Oita prefecture, in southwestern Japan. They aim to put it into commercial use in 2 years' time.
