Antora Energy’s technology utilizes graphite blocks to store excess heat. During periods of surplus power, coils within the graphite blocks are heated to temperatures exceeding 2,700°F. This stored heat can then be released continuously for up to 50 hours, emitting a beam of heat and light through a window on the container’s side. This emitted heat can be harnessed for various applications, such as heating a limestone kiln in the cement manufacturing process.
