Finland Unveils World’s Largest Sand Battery for Clean Energy
Finland’s World’s Largest Sand Battery Could Revolutionize Renewable Energy Finland just activated the world’s largest sand battery —and while it may not look impressive at first glance, it could become one of the most impactful clean energy solutions yet. The innovative system, built in the town of Pornainen, uses sand to store heat energy generated by renewable electricity. That heat can then be used to warm buildings during Finland’s harsh winters, cutting down reliance on fossil fuels and reducing heating costs. As clean energy storage becomes more important than ever, this project may answer the growing demand for sustainable, cost-effective solutions. But how exactly does a sand battery work, and why is this one so significant? Image Credits:Polar Night Energy The concept of a sand battery may sound unusual, but it’s built on solid physics. This thermal energy storage system works by heating sand—specifically, crushed soapstone—with electricity from renewabl…
