In many developing countries the exponentially growing electricity demand can be covered by using locally available, sustainable low-enthalpy geothermal resources (80-150 °C). Such low-enthalpy sources can make electricity generation more independent from oil imports or from the over-dependence on hydropower. Until now this huge energy resource has only been used by some developed countries like the USA, Iceland and New Zealand. The reason why low-enthalpy geothermal resources are not used for electricity generation is that there is still a misconception that low-enthalpy thermal fluids are fit only for direct application. The advancement of drilling technology, development of efficient heat exchangers and deployment of high sensitive binary fluids contribute to the useful application of this energy resource on a much wider scale. This book focuses on all aspects of low enthalpy geothermal thermal fluids. It will be an important source book for all scientists working on geothermal energy development. Specifically those involved in research in developing countries rich in such thermal resources, and for agencies involved in bilateral and international cooperation.

Ron DiPippo, Professor Emeritus at the University of Massachusetts Dartmouth, is a world-regarded geothermal expert. This single resource covers all aspects of the utilization of geothermal energy for power generation from fundamental scientific and engineering principles. The thermodynamic basis for the design of geothermal power plants is at the heart of the book and readers are clearly guided on the process of designing and analysing the key types of geothermal energy conversion systems. Its practical emphasis is enhanced by the use of case studies from real plants that increase the reader's understanding of geothermal energy conversion and provide a unique compilation of hard-to-obtain data and experience. An important new chapter covers Environmental Impact and Abatement Technologies, including gaseous and solid emissions; water, noise and thermal pollutions; land usage; disturbance of natural hydrothermal manifestations, habitats and vegetation; minimisation of CO2 emissions and environmental impact assessment.The book is illustrated with over 240 photographs and drawings. Nine chapters include practice problems, with solutions, which enable the book to be used as a course text. Also includes a definitive worldwide compilation of every geothermal power plant that has operated, unit by unit, plus a concise primer on the applicable thermodynamics. * Engineering principles are at the heart of the book, with complete coverage of the thermodynamic basis for the design of geothermal power systems* Practical applications are backed up by an extensive selection of case studies that show how geothermal energy conversion systems have been designed, applied and exploited in practice* World renowned geothermal expert DiPippo has including a new chapter on Environmental Impact and Abatement Technology in this new edition

Master's Thesis from the year 2006 in the subject Engineering - Power Engineering, grade: 1,0, Bochum University of Applied Sciences, language: English, abstract: This research draws conclusions from existing biomass and geothermal electricity generation systems and combines these to a hybrid plant concept which is subsequently evaluated thermodynamically, economically and in concerns of risk management. Using a hybrid power plant concept based on geothermal and biomass energy input, low enthalpy geothermal reservoirs can be utilised more efficiently for electricity generation then it was up to now possible with ordinary binary cycles. By passing the geothermal fluid through a heat exchanger to preheat the biomass boiler feedwater a classical Rankine-Cycle generates electricity with an ideal efficiency of 34%. Due to the geothermal contribution biomass is saved by the amount of 6%. This thermodynamically desirable process, however, raises economic problems as all components of conventional biomass plants as well as the source-side components of geothermal power plants become necessary. Costs for these parts accumulating at the development’s beginning only are compensated by reduced fuel costs and higher efficiencies. For geothermal exploration failure and the underachievement of the geothermal reservoir the proposed hybrid technology opens up an additional alternative. Having to have to abandon projects with inadequate qualities in former times, it is now possible to produce electricity efficiently and sustainably by the new hybrid power plant. Moreover, the dependence on the fluctuation in terms of biomass quality and prices decrease as the contribution of biomass itself is reduced. Although delivering first findings concerning these hybrid plants, this paper highlights the future research demand and suggests a list of worthwhile research topics.
