Finland turns to the world’s largest sand battery to manage renewables

A small Finnish town is using a large-scale commercial sand battery to address renewable power intermittency.

CNBC World reports that a small town in Finland is deploying the world’s largest commercial sand battery to help manage one of the key problems in the energy transition, renewable intermittency.

The outlet frames the project as a response to the timing mismatch between when renewable power is generated and when it is needed.

By shifting to sand-based thermal storage, the town aims to make renewable energy more reliable for power use beyond periods of generation.
