Peter Thiel Leads $140M Funding for Offshore Ocean-Powered AI Data Centers
Panthalassa, a US renewable energy and ocean technology company, has secured $140 million (£102 million) in Series B funding to accelerate the development of autonomous offshore computing systems powered entirely by ocean waves. The investment round was led by billionaire Peter Thiel, co-founder and chairman of Palantir Technologies, the analytics company that holds a £300 million data contract with the UK's National Health Service.
The funding round also attracted prominent investors including venture capitalist John Doerr and Time Ventures, the personal investment fund of Salesforce co-founder Marc Benioff, according to a statement from Panthalassa. The company said the capital will support the completion of its pilot manufacturing facility near Portland, Oregon, and help deploy its Ocean-3 series of floating AI computing nodes.
Panthalassa's offshore computing systems are designed to generate electricity from ocean waves and use that power to run AI inference computing. Data is transmitted back to land via satellite, eliminating the need for conventional land-based data centers and reducing pressure on strained electricity grids. The surrounding seawater provides natural cooling for AI chips, which the company says improves efficiency and extends equipment lifespan.
Thiel described the technology as opening "the ocean frontier" for future computing infrastructure, highlighting the strategic importance of moving compute capacity offshore. Panthalassa CEO and co-founder Garth Sheldon-Coulson said the company has spent the past decade developing technologies for offshore power generation, propulsion, and autonomous operation. "We're now ready to build factories, deploy fleets, and provide a sustainable new source of energy for humanity," he said.
The company plans to deploy its Ocean-3 pilot systems in the northern Pacific Ocean in 2026, ahead of planned commercial deployments in 2027. Offshore AI infrastructure could help address growing concerns around grid capacity, cooling water shortages, and permitting delays that increasingly plague terrestrial data centers, according to Panthalassa.
