- A battery that stores heat energy in sand has been installed in western Finland.
- Electricity from renewable sources is used to heat the sand to around 932°F.
- The heat energy then warms water that can be circulated around local buildings.
- It can store energy from sources that work intermittently, like wind and solar.
- It can hold renewable energy for up to months at a time.
