Storing Solar Energy As Ice For Air Conditioning
Storing Solar Energy As Ice For Air Conditioning
In Pornainen, Finland, a 10 MW sand battery designed by Polar Night Energy has been installed — heating sand to ~600 °C to store excess renewable power, and feeding heat into the local district heating system. 
The result: ~70% fewer carbon emissions from heating in that network.

"A huge sand battery is set to slash the carbon emissions of a Finnish town.
"The industrial-scale storage unit in Pornainen, southern Finland, will be the world’s biggest sand battery when it comes online within a year.
"Capable of storing 100 MWh of thermal energy from solar and wind sources, it will enable residents to eliminate oil from their district heating network, helping to cut emissions by nearly 70 per cent.
" 'It's exciting to build a large-scale thermal energy storage, which will also act as a primary production plant in Pornainen's district heating network,' says Liisa Naskali, COO at Polar Night Energy, the company behind the innovation.
" 'This is a significant step in scaling up the sand battery technology.' "
