Grid-Scale Thermal Energy Storage Yields High Efficiency in Pilot Tests

 ·  1 min read

Engineers have completed six months of continuous testing on a grid-scale thermal energy storage installation. The system demonstrated a round-trip efficiency of 74%, surpassing initial performance targets.

Addressing Intermittency in Renewable Grids
Unlike chemical batteries, thermal storage utilizes abundant materials such as crushed rock or molten salt. The low degradation rate positions the technology as a viable solution for multi-day energy dispatch requirements.
