Sand for Thermal Energy Storage
Quote
The world's first fully working "sand battery", which can store green power for months at a time, has been installed by Finnish researchers.https://www.youtube.com/watch?v=Azaf9tKJNoA
The developers said this could solve the problem of year-round supply, a major issue for green energy.
Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.
The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

Sand for Thermal Energy Storage
Quote
Discussing the idea of sand for thermal energy storage of heat for months intended for household and greenhouse heating in cold climates that get a lot of sunshine. I discuss the idea of sand verses water for heat storage and look at the different instalation aspects like piping, insulation, and solar collection from parabolic troughs and concentrated solar.https://www.youtube.com/watch?v=UvNv_gM_ZUk
