Silicon Valley investors, including Palantir co-founder Peter Thiel, have committed hundreds of millions of dollars to deploying AI data centers powered by ocean waves. This strategic move coincides with tech companies facing increasing challenges in establishing land-based AI data center projects.
A recent $140 million investment round is intended to help Panthalassa complete a pilot manufacturing facility near Portland, Oregon, and accelerate the deployment of its wave-riding “nodes.” These nodes are engineered to generate electrical power. Critically, instead of sending renewable energy to land-based data centers, these floating units would directly power onboard AI chips and transmit inference tokens—representing AI model outputs—to customers worldwide via satellite links.
Benjamin Lee, a computer architect and engineer at the University of Pennsylvania, commented, “Panthalassa’s idea transforms an energy transmission problem into a data transmission problem. Performing AI computation on the ocean would require transferring models to the ocean-based nodes and then responding to prompts and queries.”
Each node is designed as a large steel sphere bobbing on the water, with a tube-like structure extending vertically beneath the surface. Wave motions drive water upward through this tube into a pressurized reservoir. The stored water can then be released to spin a turbine generator, producing renewable energy for the integrated AI chips.
Panthalassa also highlights that the node’s AI chips would be cooled using the surrounding ocean water, offering a significant advantage over conventional data centers. Lee noted, “Ocean-based compute might offer a massive cooling advantage because the ambient temperature is so low. Land-based data centers consume substantial electricity and fresh water for cooling.”
The newest node prototype, named Ocean-3, is scheduled for testing in the northern Pacific Ocean later in 2026. This latest version measures approximately 85 meters in length, nearly matching the height of iconic structures like London’s Big Ben or New York City’s Flatiron Building, according to the Financial Times. Panthalassa has previously tested several earlier prototypes of its wave energy converter technology.
