In a bid to combat the challenges of cold polar winters, Finland is set to introduce an industrial-scale ‘sand battery’ boasting impressive power and thermal energy capacities. Developed by Polar Night Energy, this groundbreaking technology promises to revolutionize energy storage and utilization in the region.
The new sand battery, approximately 10 times larger than its pilot predecessor operational since 2022, presents a clever concept. Essentially, it comprises a sizable steel silo filled with sand or a similar solid material, heated via a buried heat exchanger at its core. This process utilizes surplus electricity from the grid, particularly during renewable energy spikes, making it an environmentally friendly solution.
