Portland Ocean Energy Startup Raises $140M From Billionaire Peter Thiel
The funding will complete a pilot manufacturing facility and accelerate Ocean-3 deployments that use wave power to run AI inference at sea.
- On Monday, Portland-based renewable energy company Panthalassa announced $140 million in Series B financing led by Peter Thiel to complete a pilot manufacturing facility near Portland, Oregon, and accelerate Ocean-3 node deployment.
- Terrestrial data centers face significant constraints including limited grid capacity and cooling water scarcity, prompting Panthalassa to perform AI inference at sea using wave power instead.
- Following successful Ocean-1, Ocean-2, and Wavehopper prototypes in 2021 and 2024, the company plans to deploy its Ocean-3 pilot series in the northern Pacific Ocean this year, generating electricity to power onboard AI chips.
- Investor John Doerr called the system a "game changer in addressing global energy needs," while Thiel stated "extra-terrestrial solutions are no longer science fiction."
- With commercial deployments planned for 2027, Co-Founder and CEO Garth Sheldon-Coulson stated Panthalassa is "ready to build factories, deploy fleets, and provide a sustainable new source of energy for humanity.
