To meet the increasing energy demands of artificial intelligence, giant data centers could be established in the oceans. Peter Thiel-backed Panthalassa has shown considerable ambition in this regard.
The explosion in the field of artificial intelligence has brought with it a colossal need for energy and infrastructure. As large language models and generative AI become more widespread, the electricity consumption and cooling requirements of the data centers running these systems have become a serious problem. To address this issue, governments and companies are investing trillions of dollars globally in data centers and their supporting energy infrastructure. Furthermore, the idea of establishing data centers in space to meet this ever-increasing energy demand is now being seriously considered. Precisely at this juncture, a new alternative has begun to emerge: Ocean power...
US-based renewable energy and ocean technology company Panthalassa has taken a significant step to turn the increasing energy demand into an opportunity. Backed by Peter Thiel (founder of Palantir), who has become influential worldwide in recent years, Panthalassa successfully raised $140 million in its latest funding round, drawing considerable attention. This latest investment round brought the company's valuation to approximately $1 billion.
Wave Energy-Powered Data Centers Are Coming
Panthalassa's systems adopt a significantly different approach from traditional data centers. The company's platforms, named Ocean-3, consist of autonomous units floating in the open ocean. These platforms generate electricity from wave motion, providing an uninterrupted power source. The critical difference here, however, is that the generated energy is not transmitted to land; instead, it is used directly to power the AI chips on the platform.
The data processing in these systems also operates unconventionally. AI models run on the platform, transmitting their results (tokens) to land via satellite connection. This eliminates the need for energy transmission and the requirement for data centers to be physically located on land.
Establishing Data Centers in the Ocean Also Provides Cooling Advantages
Another significant advantage offered by the ocean is cooling. Heat management, one of the biggest engineering challenges in traditional data centers, can be solved naturally and freely on these platforms using the surrounding seawater. This extends hardware lifespan and significantly reduces operating costs.
Panthalassa has been working on wave energy, autonomous systems, and offshore computing technologies for approximately ten years. The Ocean-1, Ocean-2, and Wavehopper prototypes, tested in 2021 and 2024, demonstrated that this concept is technically feasible. The company is now preparing to scale this technology in the real world with its Ocean-3 series. The first pilot platforms are planned to be deployed in the North Pacific in 2026. Commercial use is targeted for 2027.
According to Panthalassa CEO Garth Sheldon-Coulson, the open ocean is a vast, underexploited resource for energy generation. The company claims it can produce electricity from wave energy at a remarkably low cost of approximately $0.02 per kilowatt-hour. This could potentially make the ocean "the planet's cheapest energy source."
Of course, there are significant challenges to turning these promises into reality. Open sea conditions inherently present an extremely demanding engineering environment. Corrosion caused by saltwater, biofouling, storms, and constant mechanical stress raise questions about the long-term durability of these systems. Furthermore, the latency introduced by satellite connectivity could be a limiting factor for some AI workloads.
Despite all these concerns, Peter Thiel's backing strengthens the project's potential to become a reality. Moreover, the performance in the latest funding round indicates that investors are convinced of the project's chances of success. In short, Panthalassa could become a company we hear about more frequently in the coming years.
