Finnish companies Polar Night Energy and Vatajankoski have built the world’s first operational “sand battery”, which provides a low-cost and low-emissions way to store renewable energy.
The battery, which stores heat within a tank of sand, is installed at energy company Vatajankoski’s power plant in the town of Kankaanpää, where it is plugged into the local district heating network, servicing around 10,000 people.
