Photon Vault

Photon Vault™ is the future of energy storage. The Photon Vault is the least expensive, most resilient, and most efficient storage technology available, together with the lowest environmental impact. We combine heat and electricity to achieve electrical roundtrip efficiencies of more than 100% and can provide long-duration storage for as little as $10/kWh - 95% cheaper than Lithium-ion batteries. Short duration storage is only $135/kWh, 50% cheaper than the nearest competing technology. Also, our proprietary storage media does not degrade with each charge-discharge cycle like batteries do.
