Abstract
The two national projects on direct utilization of geothermal resources is mentioned. The merit of the projects is to utilize geothermal water which discharges, with steam, from exiting production wells of the geothermal power plants before its injection into underground. the tow power plants, Kakkonda (50MW), Iwate, and Onuma (10MW), Akita, supply 1000 the of 150°C and 150 t/h of 70°C of fresh heated water to Shizukuishi,Iwate, and Kazuno, Atika, respectively. Financial supports of 4.5 billion and 1.6 billion are offered to the Iwate and the Kazuno projects, respectively by the Agency of Natural Resources and Energy, the Ministry of International Trade and Industry, for drilling of injection wells, constructing of heat exchangers and laying of transportation pipelines.
