  • This paper is a result of work done by the Westinghouse Electric Corporation on a $1.8 million, 3 1/2 year study funded by DOE and EPRI. The potential future market for Compressed Air Energy Storage (CAES) system is substantial. The savings realized by utilizing CAES power plants can be very attractive with the proper generation mix. The thermodynamic parametric performance studies that were conducted to screen the various aquifer charging and discharging cycles are discussed. Equations are presented to directly calculate the optimum (minimum required total compressor work and air cooler heat rejection) intercooler(s) location for a compressor train utilizingmore » one and two intercoolers. An equation is also presented which directly determines the reheat combustor location required to maximize the turbine train output. A discussion is included why the performance of CAES power cycles must be optimized by considering the total power production energy costs not on a basis of maximum turbine output power or heat rate. Hardware and economic considerations which lead to CAES LP turbomachinery component standardization are discussed. Such standardization allows a manufacturer to economically adapt its CAES turbomachinery to a range of different air storage pressures.« less
  • The US Department of Energy (DOE) manages a multibillion dollar environmental management (EM) program. In June 1996, the Assistant Secretary of Energy for EM issued a memorandum with guidance and a vision for a ten year planning process for the EM Program. The purpose of this process, which became known as the Accelerated Cleanup: Focus on 2006, is to make step changes within the DOE complex regarding the approach for making meaningful environmental cleanup progress. To augment the process, Assistant Secretary requested the site contractors to engage in an effort to identify and evaluate integration alternatives for EM waste streammore » treatment, storage, and disposal (TSD) that would parallel the 2006 Plan. In October 1996, ten DOE contractor installations began the task of identifying alternative opportunities for low level radioactive waste (LLW). Cost effective, efficient solutions were necessary to meet all requirements associated with storing, characterizing, treating, packaging, transporting, and disposing of LLW while protecting the workers` health and safety, and minimizing impacts to the environment. To develop these solutions, a systems engineering approach was used to establish the baseline requirements, to develop alternatives, and to evaluate the alternatives. Key assumptions were that unique disposal capabilities exist within the DOE that must be maintained; private sector disposal capability for some LLW may not continue to exist into the foreseeable future; and decisions made by the LLW Team must be made on a system or complex wide basis to fully realize the potential cost and schedule benefits. This integration effort promoted more accurate waste volume estimates and forecasts; enhanced recognition of existing treatment, storage, and disposal capabilities and capacities; and improved identification of cost savings across the complex.« less
  • Technical considerations have been presented on the application of direct reduction to produce metallized iron ore. This material contains energy in a compact solid form that can be stored for unlimited periods of time and safely transported. Therefore, its production is a technically feasible supplement to LNG and other forms of energy. Economic considerations were then discussed with emphasis on the unusual aspects that would be required for a complete process and cost engineering analysis. In conclusion, it is interesting to note that the United States in practice today is doing exactly opposite to the concept proposed in this paper.more » This occurs as a result of large exports of steel scrap which is a material similar to metallized iron ore in that both are used for the same purpose in steelmaking furnaces and may be substituted for each other. With respect to steel scrap the energy required for its conversion into an ingot ton of steel is about 6.33 million kJ (6 million Btu). In the absence of scrap (or metallized iron ore) when iron ore is processed through the blast furnace route, about 19 million kJ (18 million Btu) are required for the same purpose. Therefore, approximately 12.66 million kJ (12 million Btu) are exported with every ton of steel scrap. The equivalent amount of energy exported is roughly 25 million barrels of oil or 150 billion cubic feet of natural gas as a consequence of exporting approximately 12 million tons per year of scrap.« less
  • A battery energy storage system for load leveling must be capable of fulfilling the requirements of each plant site. Among the requirements that vary are the size of the storage capacity, the users' demand patterns, and both environmental and cost considerations. The size selection of the battery storage capacity is influenced by each local site, the load demand patterns of subtransmission and distribution substation, and the policies of a utility. The optimum size of the battery energy storage system for load leveling has been determined after the analysis of multihundred load demand curves and the system operating mode. This operatingmore » mode is assumed to be able to convert and transfer off-peak electric energy and to convert and retrieve the stored energy when peaking time. And also, this system ac-ac converting efficiency is assumed 70 percent. The siting of a battery energy storage system is desirable at industrial and commercial areas in Japan. Charge and discharge time for load leveling are suitable 8 hours respectively. The optimum size of a battery energy storage system is estimated 10 to 30 percent of a subtransmission and distribution substation transformer capacity. In the case of installing at the distribution substation, this capacity is the range of 2 to 5 MW. In addition, economics and credits of a dispersed battery energy storage system are estimated. Study results indicate that the transmission and distribution credits of a dispersed battery energy storage system is in the range of $700 to $1060 per KW of its installed capacity.« less
  • Compressed air energy storage (CAES) is a means of producing intermediate or peaking power. CAES is based on using low cost electrical energy available during off-peak hours to compress air to a pressure of about 1000 psi, which is stored in an underground cavern for use at a later time. When there is a need for intermediate or peaking power, the compressors are shut down, the air is allowed to flow into an oil-fired or natural gas-fired combustor, and the hot, high pressure air is expanded through machinery very similar to the turbine section of a conventional gas turbine. Thismore » paper discusses how CAES is a technology which can be considered to be commercial. A 220 MW oil-fired CAES plant design was used as a baseline for this evaluation of CAES plant economics. This design features high and low pressure combustors and expanders, and also has an exhaust gas recuperator to recover heat from the exhaust gas. This paper summarizes the key design parameters of this configuration.« less
