1-GWh diurnal load-leveling Superconducting Magnetic Energy Storage system reference design
A point reference design has been completed for a 1-GWh Superconducting Magnetic Energy Storage system. The system is for electric utility diurnal load-leveling but can also function to meet much faster power demands including dynamic stabilization. This study explores several concepts of design not previously considered in the same detail as treated here. Because the study is for a point design, optimization in all respects is not complete. This report examines aspects of the coil, the superconductor supported off of the dewar shell, the dewar shell, and its configuration and stresses, the underground excavation and construction for holding the superconducting coil and its dewar, the helium refrigeration system, the electrical converter system, the vacuum system, the guard coil, and the costs. This report is divided into two major portions. The first is a general treatment of the work and the second is seven detailed technical appendices issued as separate reports. The information presented on the aluminum stabilizer for the conductor, on the excavation, and on the converter is based upon industrial studies contracted for this work.

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix A: energy storage coil and superconductor
The technical aspects of a 1-GWh Superconducting Magnetic Energy Storage (SMES) coil for use as a diurnal load-leveling device in an electric utility system are presented. The superconductor for the coil is analyzed, and costs for the entire coil are developed.

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix B: cost study, high-purity aluminum production
Cost information is supplied for aluminum with purities of 200, 2000, and 5000 residual resistivity ratio. Two production situations were used for each purity: (1) 1 x 10/sup 6/ kg/yr production rate with a 30-yr sustaining market and (2) 1 x 10/sup 6/ kg/yr production rate for 2 yrs only. These productions and purities are of interest for manufacturing devices for Superconducting Magnetic Energy Storage. The cost study results are presented as a range and include (1) the selling price of the aluminum for each case, (2) the cost of facilities including construction, engineering, and related costs, (3) the cost of money and depreciation (interest/amortization), and (4) the energy costs - the total of power and fuel. The range is affected by possible production variations and other uncertainties. Information is also given on plant location options and the preferred feed to the purification facility (with ore source effects).

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix C: dewar and structural support
The mechanical aspects of the dewar to contain a 1-GWh superconducting coil in a 1.8 K helium bath and the means for supporting the coil and dewar against the rock of an underground excavation created for just that purpose are presented.

1-GWh diurnal load-leveling superconducting magnetic energy storage system reference design. Appendix D: superconductive magnetic energy storage cavern construction methods and costs
The excavation and preparation of an underground cavern to contain a 1-GWh diurnal load-leveling Superconducting Magnetic Energy Storage (SMES) unit is examined. The cavern's principal function is to provide a rock structure for supporting the magnetic forces from the charged storage coil. Certain economic considerations indicate the refrigerator cold box for the helium system should also be underground. The study includes such a provision and considers, among other things, rock bolting, water seepage, concrete lining of the walls, steel bearing pads, a system to prevent freezing of the walls, a mining schedule, and costs.

500 kW direct contact pilot plant for East Mesa
A 500 kW powerplant utilizing a direct contact heat exchanger (DCHX) between the geothermal brine and the isobutane working fluid is nearing completion at the East Mesa Component Test Facility. The primary purpose of the plant is to evaluate the performance potential of the direct contact system in a size much larger than the small exploratory units that have been tested to date. Thermodynamic performance of DCHX binary power systems has been demonstrated in small 10 kW research test rigs (Refs. 1, 2, and 3), however, characteristics that affect the economics and practicality of long term operation need to be evaluated. Three factors influencing plant performance and cost are: (1) the control of noncondensables that contaminate the power cycle condenser, (2) the equipment required to limit working fluid losses, and (3) the control of scaling or performance robbing deposits in critical components. These factors are not unrelated and control of one often impacts control of the other two. Operating data and research with the 500 kW pilot plant should demonstrate a solution to all three of these factors and provide design guidelines for larger plants.

Advanced Fuel Cell Development Progress Report: January-March 1979
Quarterly report discussing fuel cell research and development work at Argonne National Laboratory (ANL). This report describes efforts directed toward understanding and improving the components of molten-carbonate-electrolyte fuel cells operated at temperatures near 925 K. The primary focus of this work has been the development of electrolyte structures that have good electrolyte retention and mechanical properties as well as long-term stability, and on developing methods of synthesis amendable to mass production.
