DeepGreen proposes 100 MW subsea data centers off Alaska and Maine

DeepGreen Holdings filed preliminary-permit applications with FERC to study tidal-powered subsea data centers: 66 compute pods and 300+ turbines up to 100 MW in Alaska's Cook Inlet (~1,650 acres) and a 51 MW cluster in Western Passage, Maine. Both sites overlap critical habitat for endangered whales — roughly 300 Cook Inlet belugas and fewer than 400 North Atlantic right whales. Eastport enacted a moratorium, the Passamaquoddy Tribe declined to collaborate, and FERC flagged the applications as deficient over tribal consultation.

• Alaska: 66 subsea pods and 300+ turbines, up to 100 MW on ~1,650 acres
• Maine: a 51 MW cluster of tidal-powered compute pods
• About 300 Cook Inlet belugas and fewer than 400 right whales remain
• FERC: a preliminary permit does not authorize construction
