Antora Energy is a company that uses thermal energy storage to provide a sustainable and reliable energy supply to heavy industries, such as manufacturing, construction, mining, and food processing.
Factories and data centers need continuous heat and power, but variable renewable electricity cannot always match demand.
R&D Focus
Graphite thermal batteries, industrial steam and thermophotovoltaic power generation.
Innovative Solution
Stores renewable electricity as very high-temperature heat in carbon blocks and supplies industrial heat or converts it back to electricity using thermophotovoltaic cells.
Solution Effectiveness
In May 2026, Antora and POET commissioned a 5 GWh multi-day thermal battery project using more than 200 battery units; the project moved from construction to energy delivery in under 12 months.
