🇫🇮 Finland Just Built the World's Largest Sand Battery—And It's Working. @polarnightenergy
At 13 meters tall and filled with 2,000 tons of crushed soapstone, Polar Night Energy’s new sand battery in Pornainen stores clean electricity as heat, providing up to 1MW of power with 100MWh capacity.
Here’s why it matters:
Powers an entire town with clean heat
Cuts heating emissions by 70%
Reduces oil to 0 and wood use by 60%
AI controls timing for grid stability + profit
This addresses renewables' biggest challenge: intermittency. Even when the sun doesn’t shine and wind doesn’t blow, sand stays hot—and the town stays warm.
A promising model for a scalable, low-emissions future.
