Use of Solar Energy to Produce Process Heat for Industry

K.C. Brown

The role of solar energy in supplying heat and hot water to residential and commercial buildings is familiar. On the other hand, the role that solar energy may play in displacing imported energy supplies in the industrial and utility sectors often goes unrecognized. The versatility of solar technology lends itself well to applications in industry; particularly to the supplemental supply of process heat of all kinds. The realization of that potential will depend, however, on the identification of the most suitable applications and locations for industrial solar energy and the continued improvement in cost, durability, and reliability of solar equipment. The status of solar thermal technology for industrial process heat applications is surveyed, including a description of current costs and operating histories. Because the current status is unsatisfactory in view of the goals established by President Carter for solar industrial energy, the most important objectives to be met in improving system performance, reducing cost, and identifying markets for solar IPH are outlined. The effect of government tax policy will be of little impact until technical efficiency and cost effectiveness are significantly improved.

Small power systems study. Quarterly report no. 1

John P. Thornton Cécile Bishop K.C. Brown A. L. Edgecombe

Recent studies have suggested a significant potential for small solar-thermal electric power generating plants to be used by small communities, rural areas, and remote load centers. The Small Power Systems Program has been initiated by the Department of Energy to explore the technical, economic, and institutional feasibility of small power plants. SERI, in conjunction with Jet Propulsion Laboratory and Battelle Pacific Northwest Laboratories, has been contracted by the Department of Energy to perform a comparative analysis and ranking of various solar thermal generic systems with capacities in the 1 to 10 MW/sub e/ range. The systems will be evaluated to a predetermined set of criteria which will include factors such as safety, environmental status, cost, and performance.

Goals: objects and measures of progress

K.C. Brown

One of the most useful outputs of systems and market analysis is a concise statement of technology goals. The concept of goal-setting as previously developed in other programs of research and development is introduced. In this context goals are merely the visible output of a systematic translation of market requirements into research and development actions. Cost goals are one type of information linkage between market and research, although a complete statement of technology goals must include both tangible and intangible physical requirements as well. The process of devising goals and measuring progress against these goals is briefly illustrated in an example from the Solar Industrial Process Heat Program. The process of establishing a program framework and program goals has not been completed for solar process heat; it is hoped that this paper will encourage steps in this direction.

<title>Options For Solar Thermal Conversion</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (1977)

Frank Kreith Gerard F. Lameiro K.C. Brown

This article outlines the impetus and form for one of the research tasks to be undertaken at the Solar Energy Research Institute. Two options, the high temperature option and the intermediate temperature option, are usually specified for solar energy development. Evidence is presented which supports the need for immediate research into the intermediate temperature, supplementary source role for solar thermal power in the United States. Particularly promising is a technological, approach which will match industrial process heating demands to currently available solar concentrating collector systems. The impact appears to be strong, with 19% of U.S. energy input falling at temperature demand levels less than 1770 C (3500 F). A detailed industrial process heat data base is to be assembled and matched to the system performance of major concentrator types. Solar concentrator characteristics are generally outlined and areas for immediate improvement suggested. An example of the matching of a concentrator system to a specific task is included.

Final Report: Comparative Ranking of 0.1-10 MWe Solar Thermal Electric Power Systems, Volume II: Supporting Data

John P. Thornton K.C. Brown Joseph G. Finegold James Gresham F. Ann Herlevich

This report is part of a two-volume set summarizing the results of a comparative ranking of generic solar thermal concepts designed specifically for electric power generation. The original objective of the study was to project the mid-1990 cost and performance of selected generic solar thermal electric power systems for utility applications and to rank these systems by criteria that reflect their future commercial acceptance. This study considered plants with rated capacities of 1-10 MW/sub e/, operating over a range of capacity factors from the no-storage case to 0.7 and above. Later, the study was extended to include systems with capacities from 0.1 to 1 MW/sub e/, a range that is attractive to industrial and other nonutility applications. Volume I summarizes the results for the full range of capacities from 0.1 to 1.0 MW/sub e/. Volume II presents data on the performance and cost and ranking methodology.

Industrial process end-use matching. Technical planning report

Gerard F. Lameiro K.C. Brown

Several recent studies have emphasized the potential for application of solar thermal systems to the process heating needs of industry. The potential exists for an efficient matching of output from solar collectors operating at a specified temperature to the required process temperature and heat rate of a variety of manufacturing processes. The purpose of SERI Task 3403 is to gather data on industrial process heat requirements for specific manufacturing processes and to test a number of currently available solar systems in order to determine economically optimal matches of these processes and systems at selected sites. This plan identifies three major efforts: The assembly of data bases for industrial process heat requirements, collector characteristics, local economic factors, and local climatological factors. The creation of a fast-calculating computer code to determine the long-term average annual performance of solar process heat systems (PROSYS). The analysis of economic and commercial feasibility of specific solar systems with respect to plant requirements.

Economic analysis of solar industrial process heat systems: A methodology to determine annual required revenue and internal rate of return

Unknow (1981)

W. C. Dickinson K.C. Brown

To permit an economic evaluation of solar industrial process heat systems, a methodology to determine the annual required revenue and the internal rate of return was developed. First, a format is provided to estimate the solar system's installed cost, annual operating and maintenance expenses, and net annual solar energy delivered to the industrial process. Then an expression is presented that gives the annual required revenue and the price of solar energy. The economic attractiveness of the potential solar investment can be determined by comparing the price of solar energy with the price of fossil fuel, both expressed in levelized terms. This requires calculation of the internal rate of return on the solar investment or, in certain cases, the growth rate of return.
