Photon Vault develops a thermal energy storage system that banks heat energy—harvested from solar thermal power, industrial waste heat, or other high-temperature sources—in a proprietary custom-engineered composite material, then converts a temperature gradient into a pressure gradient to drive a standard generator. The system targets grid-scale energy storage to help offset the intermittency of solar and wind power and support decarbonization of electricity supply.
