Download or read book Economic Assessment of Nine Geothermal Direct Use Applications. Final Report written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides an economic analysis of nine federally-supported geothermal direct heat applications which were part of DOE's Program Opportunity Notice (PON) program. Three of the projects analyzed were user-owned systems, and six were district heating systems. Five of the nine projects are successful from an economic standpoint and the majority of these projects are in areas where geothermal energy has long been used for heating. The results of this analysis indicate that geothermal energy projects can be economic under certain conditions, but these conditions may not be very widespread.

Available in PDF, EPUB and Kindle. Book excerpt: In this report the cost of using low temperature geothermal energy resources for direct heating applications is compared to the costs associated with conventional heating fuels. The projects compared all involved replacing conventional fuels (e.g., natural gas and fuel oils) with geothermal energy in existing heating systems. The cost of using geothermal energy in existing systems was also compared with the cost of new coal-fired equipment. The costs for the geothermal retrofit projects were estimated based on the results to date in five projects partially funded by the U.S. Department of Energy (DOE). These cost estimates are highly realistic since four of the five projects are operational and the other project is currently under construction. The five projects examined are: Diamond Ring Ranch, which uses geothermal water from a previously existing well to heat several small buildings and to dry grain on a private ranch in South Dakota. (Operational: 1979); Klamath YMCA, which uses geothermal energy to heat a swimming pool and to provide space and water heating to a YMCA Building in Klamath Falls, Oregon. (Operational: 1980); Pagosa Springs, Colorado, where the local government is developing a near-the-surface geothermal resource to provide district heating for at least 127 businesses, residences, and public facilities. (Operation planned: 1981); Philip, South Dakota, where a local government has developed a small district heating system to heat five school buildings and at least eight businesses. (Operational: 1980); St. Mary's Hospital, which provides space heating and hot water preheating to a hospital in South Dakota. (Operational: 1980).

Book excerpt: The main objectives of this study were first, to review and analyze several economic assessments of Hot Dry Rock (HDR) geothermal energy systems, and second, to reformulate an economic model for HDR with revised cost components. The economic models reviewed include the following studies sponsored by Electric Power Research Institute (EPRI)-Cummings and Morris (1979), Los Alamos National Laboratory (LANL)-Murphy, et al. (1982), United Kingdom (UK)-Shock (1986), Japan-Hori, et al. (1986), Meridian-Entingh (1987) and Bechtel (1988). A general evaluation of the technical feasibility of HDR technology components was also conducted in view of their importance in establishing drilling and reservoir performance parameters required for any economic assessment. In this review, only economic projections for base load electricity produced from HDR systems were considered. Bases of 1989 collars ($) were selected to normalize costs. Following the evaluation of drilling and reservoir performance, power plant choices and cost estimates are discussed in section 6 of the report. In Section 7, the six economics studies cited above are reviewed and compared in terms of their key resource, reservoir and plant performance, and cost assumptions. Based on these comparisons, the report estimates parameters for three composite cases. Important parameters include: (1) resource quality-average geothermal gradient (C/km) and well depth, (2) reservoir performance-effective productivity, flow impedance, and lifetime (thermal drawdown rate), (3) cost components-drilling, reservoir formation, and power plant costs and (4) economic factors-discount and interest rates, taxes, etc. In Section 8, composite case conditions were used to reassess economic projections for HDR-produced electricity. In Section 9, a generalized economic model for HDR-produced electricity is presented to show the effects of resource grade, reservoir performance parameters, and other important factors on projected costs. A sensitivity and uncertainty analysis using this model is given in Section 10. Section 11 treats a modification of the economic model for predicting costs for direct, non-electric applications. HDR economic projections for the U.S. are broken down by region in Section 12. In Section 13, the report provides recommendations for continued research and development to reduce technical and economic uncertainties relevant to the commercialization of HDR. [DJE-2005].

Available in PDF, EPUB and Kindle. Book excerpt: As part of a mission-oriented program for accelerating the commercialization of geothermal energy, research is sponsored which concerns the quantitative analysis of investment decisions by industries involved in the development of geothermal resources. The results of a quick-response study conducted during the course of this research are discussed. The report specifically compares the relative investment incentive offered by two categories of geothermal ventures: (a) geothermal electric power projects; and (b) geothermal direct application projects. The attributes of discounted cash flows for several typical projects within each of the two categories are compared and, by using statistically-strong industry decision models previously developed, the likelihood of a favorable investment decision is estimated for each project.

Available in PDF, EPUB and Kindle. Book excerpt: The economic feasibility and water quality considerations of the cultural practice of soil warming was evaluated using existing technical, agronomic, and economic data. It was hypothesized that it is technically and economically feasible to use geothermal energy in the cultural practice of soil warming for specific crops. The analysis attempted to reject the hypothesis. Since the hypothesis could not be rejected, the results are presented as a profit equation suitable for inclusion in the GEOCOST computer program. This determination of economic feasibility utilized heterogeneous crop yield data by comparing the elasticity of response with a normalized product-factor price ratio. Soil warming was determined to be feasible when the elasticity of production was equal to or greater than the normalized product-factor price ratio. A farm enterprise was determined profitable if net returns were positive. An empirical model in which the energy dissipation rate is a function of the difference between heat source temperature and mean monthly air temperature was transformed to utilize data describing the total heat applied during the growing season. Heat input was then measured as the total number of calories per square centimeter applied during the growing season.

Available in PDF, EPUB and Kindle. Book excerpt: The technical approach to the problem of comparative evaluation of the twenty economic-engineering studies on non-electric uses of geothermal energy is described which led to the development of the Geodec model. The geodec model is presented and the analyses made and the results calculated are described. The conclusions and recommendations arising from these results are discussed. Included in appendices are sample data input/output forms for each of the modules which make up Geodec and the detailed input data and calculated results for each process analyzed. Process analyses are presented including input and output data base for each of the twenty economic-engineering studies on non-electric uses of geothermal energy identified in Volume I.
