Concrete as a thermal energy storage medium for thermocline solar

At this temperature, the unit cost of energy stored in concrete (the thermal energy storage medium) is estimated at $0.88–$1.00/kW h thermal. These concrete mixtures, used as a thermal energy storage medium, can potentially change solar electric power output allowing production through periods of low to no insolation at lower unit costs.

Particle thermal energy storage is a less energy dense form of storage, but is very inexpensive ($2‒$4 per kWh of thermal energy at a 900°C charge-to-discharge temperature difference). The energy storage system is safe because inert silica sand is used as storage media, making it an ideal candidate for massive, long-duration energy storage.
