Green High-Power Solid-State Energy Storage Technologyinvolves the establishment of large-capacity thermal energy storage centersoperating at voltage levels ranging from 10 to 110 kilovolts (kV) based onpower grid. It converts surplus electricity during off-peak hours of the powergrid, as well as abandoned wind and solar energy, into stored thermal energy.This stored energy can then be utilized to replace coal and gas boilers forheating purposes when needed. This technology enables direct connection topower grids ranging from 10 kV to 110 kV, effectively overcoming the powerbottleneck associated with high-power electricity-heat conversion andlarge-scale thermal energy storage.
