Innovation

Industry Problem

Industries from paper production to concrete-making require a great deal of heat, which, to date, is typically supplied by fossil fuels like oil and natural gas.

R&D Focus

Graphite blocks to store heat

Innovative Solution

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.

Solution Effectiveness

Antora Energy’s storage system can store heat for up to 100 hours and convert it back to electricity at a cost of less than $10 per kilowatt hour (kWh).
