1-GWh Diurnal Load-Leveling Superconducting Magnetic Energy Storage System Reference Design. Appendix B: Cost Study, High-Purity Aluminum Production

摘要

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 exp 6 kg/yr production rate with a 30-yr sustaining market and (2) 1 x 10 exp 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). (ERA citation 05:003085)
