About the Company
Turning Oceans into Batteries
Joule has developed a patented ocean-based energy storage technology that solves the renewable energy industry's biggest challenge: reliable, long-duration storage at scale.
Our solution stores energy indefinitely with zero degradation, delivers power for as many hours as needed, and operates for 100+ years
without performance loss. Unlike batteries or pumped hydro, Joule's technology works anywhere there's ocean. No special geography, no fresh water, no chemical degradation, no environmental compromise.
With our patent secured (2025) and NSF SBIR Phase I invitation validating our approach, we're proving that the ocean isn't just a resource. It's the solution to grid-scale energy storage.
