Book Description
A Distributed Geothermal Market Demand Model (dGeo) has been developed to explore the potential role of geothermal district heating (GDH) systems in meeting current and future thermal energy demands in the continental United States. The dGeo model simulates the technical, economic, and market potential for deployment of GDH systems in the residential and commercial sectors through 2050. Two scenarios are considered: a Business-as-Usual (BAU) scenario assuming status-quo, and an Technology Improvement (TI) Scenario assuming significant technology advancements resulting in lower drilling and exploration costs, lower discount rates, and higher well flow rates. For known hydrothermal resources, dGeo estimates a technical, economic, and market potential of 27 GWth, 2.8 GWth, and 1.0 GWth in the BAU scenario and 27 GWth, 4.6 GWth, and 1.6 GWth in the TI scenario. For EGS resources, the corresponding values are up to two orders of magnitude higher. The simulation results are compared with current GDH systems in United States and Europe.

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
The U.S. Department of Energy's (DOE's) Geothermal Technologies Office (GTO) engaged in a multiyear research collaboration among national laboratories, industry experts, and academia to identify a vision for growth of the domestic geothermal industry across a range of geothermal energy types. The effort, called the GeoVision analysis, assessed opportunities to expand geothermal energy deployment by improving technologies, reducing costs, and mitigating barriers. The analysis also evaluated the economic and environmental impacts of such deployment - including industry growth, consumer energy prices, water use, and air emissions - and investigated opportunities for desalination, mineral recovery, and hybridization with other energy technologies for greater efficiencies and lower costs. The GeoVision analysis used a suite of modeling tools and scenarios to evaluate the performance of geothermal technologies relative to other energy technologies. The assessment included evaluating the potential role of existing and future geothermal deployment in both the electric sector and the heating and cooling sector. In the electric sector, the GeoVision analysis considered electricity generation from existing conventional (hydrothermal) geothermal resources as well as unconventional geothermal resources, such as enhanced geothermal systems (EGS). In the heating and cooling sector, the analysis modeled geothermal heat pumps (GHPs, also called ground source heat pumps) and district-heating systems using both conventional and EGS resources. The analysis culminated in a summary report, GeoVision: Harnessing the Heat Beneath Our Feet (DOE 2019), as well as eight supporting task force reports (Lowry et al. 2017, Doughty et al. 2018, Wendt et al. 2018, Augustine et al. 2019, Liu et al. 2019, McCabe et al. 2019, Millstein et al. 2019, Young et al. 2019). Among other results, key findings of the analysis indicate that optimized permitting could potentially double geothermal capacity by 2050; technology improvements could increase geothermal power generation nearly 26-fold from today; and increased geothermal deployment can provide economic and environmental benefits to the United States. The analysis also concludes that GHPs can provide heating and cooling solutions to the equivalent of 28 million households and geothermal district-heating systems could experience exponential growth - from 21 installations today to 17,500 nationwide. In addition to summarizing analytical results about geothermal energy opportunities, the report includes a Roadmap of actionable items on which the stakeholder community can engage to achieve the outcomes of the analysis. The GeoVision Roadmap is a comprehensive call to action to encourage and guide stakeholders toward the shared goal of realizing the deployment levels and resulting benefits identified in the GeoVision analysis.

Book Description
Geothermal waters, hot enough to provide direct heating, are available in many parts of the world. Some are exploited already but many more are only now being considered, as planners begin to recognize the environmental benefits of this unfamiliar energy resource. The relative economic benefits are more marginal, however, and a successful scheme requires careful design and optimization. The nature of geothermal resources imposes special conditions which may be unfamiliar to many plant engineers. In addition, many different approaches are possible, depending on the characteristics of the resource and the user and on the operator's requirements. Must the scheme be optimized for energy recovery or for financial return, or is it more important that it should remain profitable over as wide a range of conditions as possible? This book, written by professional plant engineers with first-hand experience, is designed to guide plant engineers through the different options and to help in this optimization process.

Book Description
District heating stands as a means to conserve fossil fuel through more efficient utilization of these resources as a primary source of heat because it can supplant the application of fossil fuels to a great extent by utilizing waste heat from various sources. Of paramount interest as a source of waste heat are the steam electric generating plants, especially those powered by nuclear fission. Utilization of this by-product allows immediate cutback in fossil fuel consumption. It relieves the environment from bearing the burden of huge amounts of excess heat. It opens the supply of fossil fuels to more complex applications where these are used to greater advantage. It raises the energy conversion efficiency of these electric plants considerably and is economical. Following the Introduction, Section II presents an analysis of a study of nine urban regions that collectively display a wide variation in the parameters that are the primary determinants of unit heat cost. These regions are New York City, Chicago, Philadelphia, Los Angeles, Baton Rouge, New Orleans, Jersey City, Newark, and Paterson. They show great variety in climate, size, population and population density, housing profile, working conditions, and labor costs. The goal of the analysis is to project heat demand in each region, design appropriate hot water piping systems to distribute this heat, and compute unit heat costs based on district heating system capital and operations costs and yearly heat demand. Section III presents a generalization of this analysis. Section IV discusses various technical and economic aspects of the adaptation of electric plants to a dual role as heat-electric energy sources. Section V contains the concluding remarks. (MCW).
