Basic research needs and priorities in solar energy. Volume I. Executive summary. Technology crosscuts for DOE

Description: This report identifies, describes, and recommends priorities for basic research important to the future development of solar energy. In response to a request from the US Department of Energy, SERI surveyed more than 120 leading scientists who were engaged in or knowledgeable of solar-related research. SERI scientists relied heavily on the opinions of scientists polled, but weighted their own recommendations and opinions equally. The result is an amalgam of national scientific opinion representi… more

Thermoelectric properties of bismuth-antimony thin films

Description: Thermoelectrics have a wide range of potential applications in the temperature range of 0/sup 0/ to 100/sup 0/C. In an effort to enhance the feasibility of thermoelectrics, we have begun investigation of potentially cheaper materials and cheaper techniques for thermoelectrics. Two features of bismuth and antimony have influenced our work. First, Horst and Williams have reported quite respectable figure of merit values in bulk single crystals of bismuth-antimony, up to 2.5 x 10/sup -3/ at room t… more

Solar ponds and their applications

Description: Solar ponds are probably the simplest and least expensive technology for conversion of solar energy to thermal energy. The solar pond is unique in its ability to act both as collector and as storage. The cost of a solar pond per unit area is considerably less than that of any active collector available today. The combination of their economic and technical factors make solar ponds attractive for district heating and industrial process heat applications. Solar ponds have the potential to displac… more

Solar ponds

Description: The different types of solar ponds are described, including the nonconvecting salt gradient pond and various saltless pond designs. Then the availability and cost of salts for salt gradient ponds are discussed and costs are compared. A simple computational model is developed to approximate solar pond performance. This model is later used to size solar ponds for district heating and industrial process heat applications. For district heating, ponds are sized to provide space conditioning for a gr… more

Salt concentration gradient solar ponds: modeling and optimization

Description: A computer simulation design tool has been developed to simulate dynamic thermal performance for salinity gradient solar ponds. This program will be available to the public through the SERI Solar Analysis Methods Center. Dynamic programming techniques are applied to allow significant user flexibility in analyzing pond performance under realistic load and weather conditions. Finite element techniques describe conduction heat transfer through the pond, earth, and edges. Results are presented that… more

Solar ponds

Description: This report first describes the different types of solar ponds including the nonconvecting salt gradient pond and various saltless pond designs. It then discusses the availability and cost of salts for salt gradient ponds, and compares the economics of salty and saltless ponds as a function of salt cost. A simple computational model is developed to approximate solar pond performance. This model is later used to size solar ponds for district heating and industrial process heat applications. For … more

Solar ponds for industrial process heat

Description: Solar ponds offer perhaps the simplest technique for conversion of solar energy to thermal energy, which can be used for industrial process heat. It is unique in its capability in acting both as collector and storage. Further, the cost of solar pond per unit area is less than any active collectors available today. Combination of these economic and technical factors make solar ponds attractive as a fuel saver in IPH applications. Detailed calculations are given for solar ponds in two specific ap… more

Solar ponds for district heating and electricity generation

Description: System requirements, performance, and costs for the application of solar ponds to district heating and to electricity generation are considered. The optimal sizing and configuration of the solar ponds themselves are emphasized, but other system features are also investigated and discussed. Performance and costs range widely, depending upon location and component costs, particularly upon salt costs for the salt gradient pond. Distribution cost for district heating is also an important parameter … more

Thermoelectric Ocean Thermal Energy Conversion

Description: A novel thermoelectric OTEC concept is proposed and compared with the ammonia closed-cycle designs. The thermoelectric OTEC is a much simpler system which uses no working fluid and therefore requires no pressure vessel, working fluid pumps, or turbogenerator. These components are replaced by power modules which are heat exchangers integrated with thermoelectric generators. The thermoelectric OTEC offers several potential advantages including: simpler and more easily mass-produced components; hi… more

Analysis of the application of thermogalvanic cells to the conversion of low grade heat to electricity

Description: Aqueous thermogalvanic cells, the solution analogs of solid-state thermoelectric devices, are compared for power generation. Measurements on the copper/copper formate/copper system yield thermoelectric powers, (..delta..E/..delta..T)/sub I=O/, of 1.25 - 1.9 mV/degree, which are higher than those exhibited by other copper systems. In these solutions three copper formate complexes are present. Practical cells were built and tested. The power output is largely limited by cell resistance, though ma… more

Conversion system overview assessment. Volume II. Solar-wind hybrid systems

Description: Solar-wind hybrid systems are discussed. It is shown that there are large areas in the United States where solar and wind resources are comparable in magnitude and there are diurnal and seasonal complementarities which offer the potential for cost-effective hybrid systems. There are also distinct engineering features of the two conversion technologies. Electric power generation from wind is straightforward and cost-effective, whereas solar thermal conversion to generate heat is more cost-effect… more

Conversion system overview assessment. Volume 1: solar thermoelectrics

Description: An assessment of thermoelectrics for solar energy conversion is given. There is significant potential for solar thermoelectrics in solar technologies where collector costs are low; e.g., Ocean Thermal Energy Conversion (OTEC) and solar ponds. Reports of two studies by manufacturers assessing the cost of thermoelectric generators in large scale production are included in the appendix and several new concepts thermoelectric systems are presented.
