Book Description
Geothermal district heating experience in the U.S. is reviewed and evaluated to explore the potential impact of utilizing this frequently undervalued renewable energy resource for space and hot water heating. Although the first U.S. geothermal district heating system (GDHS) was constructed in the 1890s in Boise, Idaho, growth in the sector has been slow. Currently there are only twenty-one operating GDHS in the U.S. with a capacity of about 100 MW thermal. In this study the main barriers and enablers to the growth of district heating were identified and investigated. Initially a literature review and interviews with current U.S. district heating operators were used to collect data on various aspects of the systems and their development. Based on analysis of the data and the current structure of the geothermal district heating regulatory and market environment in the U.S. recommendations on how to advance geothermal district heating in the U.S. are developed. Technical feasibility of increasing the geothermal district heating capacity to 10,000 MWt was established by identifying the available resource and technology for utilization. Furthermore, the opportunity presented by Engineered Geothermal System (EGS) was briefly explored. Social feasibility was analyzed and the need for geothermal energy education and expanded resource exploration was recognized. Furthermore, it is hypothesized that most government support for GDHS will come from state governments in the future and the importance of well structured incentives that support the growth of sustainable GDHS emphasized. Legal and regulatory barriers were reviewed along with the economic feasibility of GDHS. The economic analysis revealed competitive levelized energy costs and that rising drilling costs might be a barrier to GDHS development. A modest investment of about five billion dollars is needed to increase U.S. GDHS capacity to 10,000 MW thermal.

Book Description
This collection of information was assembled for the benefit of future geothermal system designers and existing system operators. It is intended to provide insight into the experience gained from the operation of 13 major geothermal systems over the past several years. Each chapter contains six or seven sections depending upon the type of system: introduction, production facilities, distribution, customer connections, metering and disposal. Some chapters, covering systems which incorporate a closed distribution design include a section on the central mechanical room. Each section details the original equipment and materials installed in that portion of the system. Following each section is a discussion of the subsequent problems, solutions and modifications relating to the equipment. The extent to which information was available varied from system to system. This is reflected in the length and level of detail of the chapters.

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.
