Hot dry rock system. New technology for geothermal energy utilization.
Journal of the Fuel Society of Japan, 1988 Geothermal Energy is one of the most important national energy resources. In Japan, nine geothermal energy power plants are under operation and produce 21.5MW by developing a natural hydrothermal reservoir located in a depth of 1, 000m to 2, 000m. In order to increase the electric power from geothermal reservoir, hot dry rock in a high temperature ...

Research on a novel type of hot dry rock power generation system coupled with Kalina and ORC
Energy Reports, 2022 To improve the utilization of hot dry rock resources, a novel type of hot dry rock power generation system is proposed in this paper. In this system, the Kalina system is coupled with the organic Rankine cycle (ORC) system. Combined with the operating parameters of the geothermal power generation project in Husavik, Iceland, the parameters of the ...

Temperature-dependent scale precipitation in the Hijiori Hot Dry Rock system, Japan
Geothermics, 2008 Mineral scales were formed in wells and surface installations during a 2-year circulation test performed at the Hijiori Hot Dry Rock (HDR) site, Yamagata, Japan. Anhydrite deposited in the deeper parts of the production wells, while silica and calcium carbonate precipitated at the surface, downstream of the wellhead, in amounts that depended on the ...
