Economic viability of geothermal energy usage in comparison to renewable and conventional energy systems; Wirtschaftlichkeit geothermischer Energiegewinnung im Rahmen regenerativer und konventioneller Energiesysteme

Abstract

This comprehensive lecture given by Prof. Dr. Gunter Schaumann in Bad Duerkheim, Germany, discusses the use of geothermal energy in relationship to other forms of renewable energy sources and conventional energy technologies used to provide heat, power and motive force. The characteristics of geothermal energy from various sources and examples of its possible use are discussed. In particular, the paper deals with deep geothermal energy, which can provide heating energy for district heating schemes, if necessary with the help of heat pumps. The prospects of such a use of geothermal energy in the next 50 years in various suitable regions in Germany is discussed and the associated prerequisites are listed. The present situation concerning the use of geothermal energy in Germany is examined. An example of a geothermal heating power station that also features a gas-fired combined heat and power installation, a heat pump and a peak-load boiler is given. Also, the generation of electrical power using the Organic Rankine Cycle is discussed. The factors influencing the economic viability of geothermal power stations are discussed in detail and the resulting energy prices are compared with conventional plants. The paper gives details of the calculation of investment and energy costs for  More>>
