Finland has launched the world's largest sand-based battery, using crushed rock for thermal energy storage. This innovative system heats sand with renewable electricity, storing enough heat for a week of heating in winter. Located in Pornainen, the system utilizes discarded soapstone, enhancing both economic and ecological aspects. The sand battery can potentially reduce the town's reliance on oil and wood for heating, slashing carbon emissions dramatically. Additionally, it maintains a high temperature outlet and promises significant efficiency in thermal storage compared to traditional methods, indicating a shift towards sustainable energy solutions.
The world's largest sand-based battery in Finland offers a cheap and eco-friendly method for thermal energy storage, potentially revolutionizing district heating systems.
By utilizing discarded soapstone, the sand battery not only cuts carbon emissions but also reduces dependence on oil and wood chip burning for heating.
