摘要

Excess energy from various sources can be stored in molten salts (MS) in the 565 °C range. Large containers can be used to store energy at excess temperatures in order to generate eight hours or more of electricity, depending on the container size, to be used during peak demand hours or at night for up to a week. Energy storage allows for a stable diurnal energy supply and can reduce the fluctuation due to weather conditions experienced at thermal solar power stations. Supported by Office of Naval Research (ONR), this paper discusses the design considerations for molten salt storage tanks. An optimal molten salt storage tank design layout is presented, as well as alternative designs for the storage tanks. In addition, the costs and corrosion effects of various molten salts are discussed in order to show the effects these considerations have on the design process.
