Solar Heat Storage

Energy Storage not only plays an important role in conservinq the energy but also improves the performance and reliability of a wide range of energy systems. Energy storagp. leads to saving of premium fuels and makes the system morA cost effective by reducing the wastage of energy. In most systems there is a mismatch between the energy supply and energy demand. The energy storage can even out this imbalance and thereby help in savings of capital costs. Enerqy storage is all the more important where the enerqy source is intermittent such as Solar Energy. The use of jntermittent energy sources is likely to grow. If more and more solar energy is to be used for domestic and industrial applications then energy storage is very crucial. If no storage is used in solar energy systems then the major part of the energy demand will be met by the back-up or auxiliary energy and therefore the so called annual solar load fract]on will be very low. In case of solar energy, both short term and long term energy storage systems can be used whjch can adjust the phase difference between solar energy supply and energy demand and can match seasonal demands to the solar availability respectively. Thermal energy storage can lead to capital cost savings, fuel savjngs, and fuel substitution in many application areas. Developing an optimum thermal storaqe system is as important an area of research as developinq an alternative source of energy.

Several hundred technically acceptable PCMs were identified in Volume I of this set, and some of their thermodynamic and physical properties were present. Out of these, practical considerations have reduced the list to a few commercial PCMs for solar energy thermal storage heating and cooling applications. In Volume II these PCMs and their technology and discussed.

Solar Collectors, Energy Storage, and Materials covers the materials and basic components needed for solar thermal energy systems. Using thermal performance and durability as the major criteria, the twenty six chapters emphasize the modeling and assessment of devices rather than their application or cost. Each part begins with an overview and concludes with an assessment of current issues and opportunities. The contributors have been careful to document failures as well as successes in materials research. This is the fifth volume in a series that distills the results of the intensive research on and development of solar thermal energy conversion technologies from 1975 to 1986. Francis de Winter is President of the Altas Corporation, Santa Cruz, California and a member of the Santa Cruz Energy Advisory Committee. Contents: Solar Collectors. Collector Concepts and Designs.
