Sand-Based Carnot Battery Prototype Tests a Different Path for Long-Duration Storage
Researchers at Aalto University evaluated a Stirling engine-based Carnot battery prototype that stores electricity as heat in sand, then converts part of it back into electricity.
Key Takeaways
- Aalto University researchers tested a Stirling engine-based Carnot battery using sand as thermal storage.
- Higher engine temperatures improved power output and run time.
