One of the biggest challenges with renewable energy like wind and solar is storing excess power when production outpaces demand. Pornainen, Finland has a novel way to address this issue: a sand battery. By converting surplus electricity into heat and storing it in superheated sand, or soapstone, this system can hold energy for days or even weeks. That heat is then fed into the town’s district heating network, reducing reliance on oil and wood chips and cutting carbon dioxide emissions by nearly

Finland has activated the world's largest sand battery in Pornainen, an industrial-scale thermal storage system that stores renewable energy as heat. This 13-meter-tall silo holds 2,000 tonnes of crushed soapstone, capable of storing 100 MWh of energy for weeks or months. Surplus electricity from wind and solar powers a resistive heater, which sends hot air through pipes to heat the soapstone to temperatures between 500°C and 600°C. This high-temperature heat is retained with a round-trip effici

In southern Finland, a small town called Pornainen is using the world’s largest sand battery to store renewable energy as heat. This innovative system uses recycled soapstone sand to capture excess solar and wind energy, heating it and storing that heat for months. The battery is built with steel–insulation–steel layers to prevent heat loss, while closed-loop pipes run through the sand to move heat in and out. When heating is needed, cool air flows through the system, capturing the stored heat a

The Pornainen sand battery stands approximately 13 meters tall and 15 meters wide, containing nearly 2,000 tonnes of crushed soapstone—a local byproduct of the fireplace industry. This innovative material is heated to between 500°C and 600°C using surplus renewable electricity from wind and solar power. Once charged, the battery can store thermal energy for weeks or even months with minimal loss. The system provides a storage capacity of 100 MWh and a thermal power rating of 1 MW, allowing it to
