As efficient as solar - thermal power plants using parabolic troughs with molten salt storage systems like Andasol 1 or Solana are, they don't capture as much of the sun's heat as is possible. (scientificamerican.com)
Electricity from a solar - thermal power plant costs roughly 13 cents a kilowatt - hour, according to Glatzmaier, both with and without molten salt storage systems. (scientificamerican.com)
These are not exceptional: a plant in Chile, Cerro Dominador, is planned to have 17.5 hours of molten salt storage if its owner EIG Global Energy Partners can find $ 800 million to restart the project after its original joint venture partner, the distressed Spanish firm Abengoa, pulled out.
