Work under this project has ultimately focused on the development of a modular packed bed based thermal energy storage system. The design assumes the use of standard segments of carbon steel pipe filled with spherical materials creating a packed bed. These materials are assumed to be manufactured in such a way that the spherical shape is uniform throughout the packed bed. Out of 32 candidate materials evaluated, 8 materials remain. Each material meets the Phase I milestones that were specified for this storage system: a round trip efficiency in excess of 93%, and a required volume of packed bed material that does not exceed the volume of molten salt used in a two-tank storage system with equivalent thermal performance.
