Antora Energy is a San Jose, California clean-energy hardware company founded by Justin Briggs, Andrew Ponec and David Bierman that designs, manufactures and deploys factory-built thermal batteries for heavy industry, data centers and the grid. Antora's system resistively heats blocks of solid carbon to temperatures up to 2,400C when electricity is cheapest, stores that energy for multiple days in a compact modular unit, and discharges it around the clock as radiant heat delivered directly to industrial processes or paired with off-the-shelf steam turbine equipment for firm power; the company also develops thermophotovoltaic (TPV) heat-to-power cells at what it describes as the world's largest TPV manufacturing line. Its HeatCore product delivers heat up to 375C at 300 kW-thermal per module, and its power block is rated at 50 MW-electric. Antora's first giga-scale deployment, Project Big Stone, is a 5 GWh system of more than 200 thermal batteries at POET's bioprocessing plant in Big Stone City, South Dakota, built from empty lot to energy delivery in under twelve months. The company closed a $550 million Series C in 2026. Antora sells energy hardware and long-term energy offtake rather than software: it publishes no developer program, no public API, no SDK and no machine-readable API contract, and its only public software surface is Insight, an authenticated steam and power optimization dashboard for named project stakeholders.
