The World’s Largest Sand Battery Just Went Online in Finland. It could change renewable energy
The world’s largest sand battery has just been turned on. The battery, which is simple in design, can store heat during periods of excess renewable energy. It then stores the heat and can deliver it on demand, enabling municipalities to eliminate fossil fuels from the heating network.
With this approach, Finnish company Polar Night Energy can store 1,000 megawatt-hours of heat for weeks at a time, losing only around 10% of the heat.
