Drogue raises $20M to power floating data centres with ocean heat
Nov 13, 2026
The six-month-old startup plans a multi-megawatt prototype on a ship at sea in early 2028.
Drogue, a Washington, D.C. startup founded six months ago, has raised $20 million to power floating data centres with energy from the ocean's heat, TechCrunch reports. Investors include XYZ Venture Capital, Toyota Ventures and Slow Ventures.
Its system uses ocean thermal energy conversion: warm surface water cools the servers and then boils ammonia that drives a turbine, while cold water pumped up from 1,000 metres condenses it again. Data centres suit the setup because shipping data off a platform is cheap, unlike sending power to shore. Drogue has preliminary approval from the American Bureau of Shipping and is buying its first ship for a multi-megawatt prototype due at sea in early 2028.
