Enhanced-Geothermal-Systems, Hot-Dry-Rock Systems, Deep-Heat-Mining

With Enhanced-Geothermal-Systems (EGS) the deep underground is used as a source of heat for the production of electrical and thermal energy irrespective of the hydraulic properties of the deep heat reservoir. In other words the rocks are hot at depth irre

Preface

Geothermal energy is an inexhaustible source of thermal and electrical energy on a human time scale. Its utilization is friendly to the environment and supplies base-load energy. The energy source does not depend on weather, and the energy is supplied 24 h per day during 7 days a week. Utilization of geothermal energy increases the regional and local net product. It relieves dependence from fossil fuels and helps to conserve the valuable chemical resources for the future. Deep geothermal resources provide thermal and electrical (converted thermal) energy thus providing reliable energy for the future. Utilization of deep geother
