Antora Energy

Delivering zero-carbon industrial heat and power.





Sunnyvale, California



Company Description

Antora Energy is electrifying heavy industry with zero-carbon heat and power. We make it possible and profitable to fully rely on renewable energy for industrial processes. Antora Energy's thermal energy storage soaks up excess solar and wind electricity and uses it to heat blocks of carbon so they glow like inside a toaster. This thermal energy is then delivered to customers as electricity or industrial process heat up to 1500°C, on demand. In short, Antora Energy turns sunshine and wind into 24/7 heat and power, cheaper than fossil fuels. Our future hinges on heavy industry. Antora Energy’s technology eliminates the need to burn fossil fuels for industrial heat and power, the biggest source of greenhouse gasses on earth.
