DOE funds to stretch solar power via salt storage

The DOE said Friday that it has made $62 million available to 13 companies to test equipment and materials, such as molten salts, to add storage to solar power systems that use heat to produce electricity.
Concentrating solar power, in which the sun’s heat creates steam to drive an electricity turbine, is seeing a renaissance because it can be used for large-scale power plants in deserts. Adding storage can extend the time these plants supply electricity to the grid and can potentially improve the economics of solar versus fossil fuels.
