Low-Enthalpy Geothermal Resources for Power Generation


Book Description

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.

With case studies for integrated geothermal energy sources for multigenerational aims, engineers can design and develop new geothermal integrated systems for various applications and discover the main advantages of design choices, system analysis, assessment and development of advanced geothermal power systems. Explains the ability of geothermal energy power systems to decrease global warming Discusses sustainable development strategies for using geothermal energy sources Provides new design conditions for geothermal energy sources-based district energy systems




Geothermal Energy


Book Description

Historically, cost effective, reliable, sustainable, and environmentally friendly, use of geothermal energy has been limited to areas where obvious surface features pointed to the presence of a shallow local heat source, such as hot springs and volcanoes. However, recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as modular power generation, home heating, and other applications that can use heat directly. These recent developments have greatly expanded opportunities for utilizing geothermal energy. Reflecting current interest in alternative energy, Geothermal Energy: Renewable Energy and the Environment explores where geothermal energy comes from and how to find it, how it can be accessed, successful applications, and improvements for future uses. The author reviews the background, theory, power generation, applications, strengths, weaknesses, and practical techniques for implementing geothermal energy projects. He stresses the links between acquisition and consumption and the environment. Packed with real world case studies and practical implementation steps, the book covers geosciences principles, exploration concepts and methods, drilling operations and techniques, equipment needs, and economic and environmental topics. Each chapter includes an annotated list of key sources that provide useful information beyond that contained in the text. The minor environmental impacts caused by geothermal energy gives it the potential to play an important role in the transition from fossil fuels to more sustainable fuels. Successful deployment, however, requires that the resource be matched to the application being developed. Rigorously covering all aspects of geothermal energy, this book provides up-to-date scientific information that can be used to discern applications and regions best suited for geothermal energy. Author William E. Glassley was recently interviewed on The Kathleen Show about using geothermal energy to heat and cool our homes.







Geothermal Resources: An Energy Alternative


Book Description

Developments in Economic Geology, 12: Geothermal Resources: An Energy Alternative focuses on the consideration of geothermal resources as alternative energy sources. The publication first elaborates on the energy outlook, basic concepts, and heat transfer. Discussions focus on temperature, heat, and its storage, heat conduction, radiation, and convection, temperatures within the earth and heat flow, volcanoes and plate tectonics, geothermal resource assessment for the U.S., and recoverability from U.S. geothermal resources. The text then ponders on geothermal systems and resources, exploration techniques, and assessment and exploitation. Concerns cover drilling technology, reservoir physics and engineering, geological and hydrological techniques, geochemical techniques, and types of geothermal systems. The book takes a look at the world-wide status of geothermal resource utilization and the Cerro Prieto geothermal field in Mexico, including geothermal manifestations, transportation of steam, and environmental factors and waste disposal. The publication is a valuable reference for alternative energy experts and researchers interested in geothermal energy resources.




Geothermal Energy


Book Description

Geothermal energy refers to the heat contained within the Earth that generates geological phenomena on a planetary scale. Today, this term is often associated with man's efforts to tap into this vast energy source. Geothermal Energy: utilization and technology is a detailed reference text, describing the various methods and technologies used to exploit the earth's heat. Beginning with an overview of geothermal energy and the state of the art, leading international experts in the field cover the main applications of geothermal energy, including: electricity generation space and district heating space cooling greenhouse heating aquaculture industrial applications The final third of the book focuses upon environmental impact and economic, financial and legal considerations, providing a comprehensive review of these topics. Each chapter is written by a different author, but to a set style, beginning with aims and objectives and ending with references, self-assessment questions and answers. Case studies are included throughout. Whilst written primarily for professionals and students interested in learning more about geothermal energy, the book also offers those new to the field and the general geothermal community an opportunity to understand and review the potential of this exciting alternative energy source.

Geothermal Energy Systems


Book Description

Geothermal Energy Systems The book encounters basic knowledge about geothermal technology for the utilization of geothermal resources. The book helps to understand the basic geology needed for the utilization of geothermal energy, shows up the practice to make access to geothermal reservoirs by drilling and the engineering of the reservoir by enhancing methods. The book describes the technology to make use of the Earth?s heat for direct use, power, and/or chill and gives boundary conditions for its economic and environmental utilization. A special focus is made on enhanced or engineered geothermal systems (EGS) which are based on concepts which bring a priori less productive reservoirs to an economic use. From the contents: Reservoir Definition Exploration Methods Drilling into Geothermal Reservoirs Enhancing Geothermal Reservoirs Geothermal Reservoir Simulation Energetic Use of EGS Reservoirs Economic Performance and Environmental Assessment Deployment of Enhanced Geothermal Systems plants and CO2-mitigation




Geothermal Energy and Society


Book Description

This book addresses the societal aspects of harnessing geothermal resources for different uses, such as power production, heating and cooling. It introduces a theoretical framework for a social scientific approach to the field, and presents a preliminary collection of empirical case studies on geothermal energy and society from across the world. By providing a conceptual and methodological framework to the study of geothermal energy and societies, it brings together information and analyses in the field that to date have been sparse and fragmented. The contributors explore the diverse aspects of the relationship between the harnessing of geothermal resources and the societies and local communities in which these developments take place. After introducing geothermal technologies, renewable energy concepts as well as their social and policy context and the regulative and environmental aspects of geothermal energy, the book analyzes and discusses twelve global case studies, and compares the social engagement tools applied with those used in other sectors. Of interest to researchers from a range of disciplines who wish to explore the issues surrounding energy and society, it is also a valuable resource for geothermal experts and postgraduate students wish to study the field in greater detail.
