Solar energy storage program: FY79
Abstract
A ranking methodology was developed for selection of thermal energy storage technologies for solar thermal applications. The ranking is based on cost and performance data. Thermal storage value data based on costs of alternative energy systems were generated for electric power plants and will be used for cost goals as a preliminary thermal storage screening tool. A survey was completed of thermal energy storage technologies, projects, and economics. An analysis was made of latent heat storage for solar heating based on previous system simulations. The only major advantage shown for latent heat storage is a reduced storage volume and not the improved solar system performance frequently postulated. Therefore, latent heat storage must be competitively priced with sensible heat options. Direct contact latent heat storage offers satisfactory low cost potential and could be used for a wide range of temperatures.
