Geothermal energy: technological aspects of exploitation

Abstract

Discusses the exploitation of geothermal energy once hot aquifers have been located. The drilling method is briefly described, and various steam cycles considered along with the choice of prime mover for the turbines. It is concluded that geothermal energy is best suited to the provision of base load in an integrated power system. District heating, hot water, and air conditioning applications are considered, e.g. in Reykjavik. Also considered are industrial applications such as the use of tepid water in fish farming, de-icing of roads, soil warming etc. Corrosion and pollution problems are examined and future prospects discussed
