Grid-Scale Thermal Energy Storage Demonstrates 82% Round-Trip Efficiency

 ·  1 min read

Engineers at a European energy research consortium published validated performance metrics from a 50-megawatt thermal storage test facility, recording an 82% round-trip efficiency rate.

Mitigating Renewable Intermittency
The system utilizes sensible heat in molten nitrate salts to capture excess mid-day solar generation. The stored energy can then drive steam turbines during peak evening demand hours without carbon output.
