摘要

Supported by Office of Naval Research (ONR), this paper presents a survey of molten salt technology used in solar power storage. Excess energy from solar power stations and other baseline power production methods can be stored in molten salts (MS) in the 565°C range, therefore allowing the use of large containers to store energy for up to a week and generate eight hours of electricity or more to be used during peak demand hours, at night, or adverse weather conditions, depending on the container size. The technology could also be used to conserve the spin off energy in the grids from nuclear or coal power production. Real life examples of concentrating solar power (CSP) plants, both domestically and worldwide, are presented with details about the type of solar collection, capacity, and energy production. Commercial solar power stations have been constructed in the United States and overseas, particularly in Spain, with molten salt being considered for use in these facilities. Some facilities use a field of flat mirrors and collection towers while others use parabolic troughs.
