Year: 1980 The technical and economic feasibility of using hydrothermal resources as a primary power source for both existing and future aluminum reduction plants in the United States is explored. Applicable hydrothermal resources that should be considered by the aluminum industry for this purpose were identified and evaluated. This work also identified the major institutional parameters to be considered in developing geothermal energy resources for aluminum industry use. Based on the findings of this study, it appears technically and economically feasible to power existing aluminum reduction plants in the Pacific Northwest using electricity generated at Roosevelt Hot Springs, Utah. It may also be feasible to power existing plants located on the Gulf Coast from Roosevelt Hot Springs, depending on the cost of transmitting the power; PNL-3174 Title: Assessment of geothermal energy as a power source for US aluminum reduction plants Author: Enderlin, W.I.

  	Citation × Citation Citation Abstract Copy Title: Utilization of geothermal energy for methane production for J. A. Albertson Land and Cattle Company Author: Bissell, R.R. Year: 1980 To utilize the geothermal energy in the area of its 30,000-head cattle feedlot, J.A. Albertson Land and Cattle Co. is considering the development of an integrated geothermal/bioconversion system that would use the cattle manure as a feedstock for an anaerobic-digestion plant to produce methane plus a digester-residue cattle-feed supplement. The feedlot lies within a high-temperature gradient and heat-flow area associated with the Western Snake River basin in Malheur Co., Oregon. The three digesters designed for the process will operate mesophilically (at 98/sup 0/F) with a 20-day retention time. To make up the digesters' heat losses, the geothermal water source will need to be about 135/sup 0/F and have a flow rate of 120-240 gpm, depending on the size ultimately selected for the facility. If the digester residue replaces alfalfa hay in the cattle's current rations, its value will amount to $1.15 million/yr. Burning the methane in engine/generator sets would produce 985-1970 kW of electric power that could be either sold or used as a day-to-day substitute for the geothermal heat.

  	Citation × Citation Citation Abstract Copy Title: Long-Term Supply Curves for Geothermal Energy - The Impacts of Technology Author: Fassbender, L.L. Year: 1980 Near-term and long-term supply curves are presented for electric applications of geothermal energy. The GEOCOST model was used to determine the present and future energy production costs for the high-temperature and intermediate-temperature hydrothermal resources identified by the USGS The long-term supply curves illustrate the potential shifts in the near-term supply curve which would result from certain technology improvements currently being pursued. Programs with the most significant potential impacts are those which result in large reductions in drilling cost, those which lead to development of commercial high capacity downhole pumps, and those which lead to large increases in the plant capacity factor. Curves were drawn to show the impacts of individual technology improvements and also to show the cumulative impacts of combinations of technological advances expected to be achieved by 1982 and 1985. Successful completion of all the programs evaluated would result in a cumulative cost reduction of $90 billion (not discounted) in electrical generating costs from the identified hydrothermal resources Title: Long-Term Supply Curves for Geothermal Energy - The Impacts of Technology Author: Fassbender, L.L.
