Drogue raises $20M to build a data center that runs on the ocean
What's the deal? Drogue has raised $20 million to develop an ocean-thermal data-center concept that both cools servers and generates power, co-founder and chief executive officer Sam Sipe said. The founded-in-2025 startup plans to send a multi-megawatt prototype to sea aboard a conventional ship in early 2028.
What's the endgame? Drogue is designing offshore floating data centers that make their own electricity using ocean thermal energy conversion, which draws power from the temperature gap between warm surface water and cold water a thousand meters down. Surface water first cools the servers, then transfers heat to an ammonia loop that vaporizes to drive a turbine; deep water, averaging about 4°C, condenses the ammonia back to liquid.

Why now? Connecting new US data centers to the grid can take up to seven years, pushing developers to seek power and cooling elsewhere. Sipe described the sector as "a real estate game."
Sipe said Drogue is buying its first vessel and has preliminary "approval in principle" from the American Bureau of Shipping. Later versions could use floating structures resembling offshore oil platforms.
What could go wrong? The technology works best in tropical regions where the surface-to-deep temperature difference stays above 20°C year-round, limiting where Drogue can deploy. Offshore data centers remain an unproven concept, with no evidence yet they can run reliably or economically at scale.
The signal: Drogue's raise adds to early investor interest in moving computing offshore, following Panthalassa's $140 million round in May for wave-powered ocean data centers. The approaches differ — Panthalassa leans on wave power, Drogue on ocean thermal energy — but both bet that the sea can ease the land, power, and cooling limits now squeezing the AI buildout.
