Cook Inletkeeper opposes subsea data center project

Cook Inletkeeper, a conservation organization based in Homer, Alaska, has announced plans to formally oppose a proposed underwater data center near Nikiski. The organization intends to file a motion to intervene against DeepGreen Cook Inlet SPV LLC’s subsea computing development in Upper Cook Inlet.

The project involves approximately 330 to 350 tidal turbines and 66 underwater computing modules, with an expected generation capacity of about 100 megawatts. The system would utilize seawater for cooling via copper-nickel alloy fins.

Inletkeeper argues that the infrastructure could introduce noise, excess heat, and pollutants into the Forelands area. They cite potential threats to commercial fisheries, salmon migration, and endangered beluga whales. The Federal Energy Regulatory Commission is currently considering an application to study the project’s feasibility, with a public comment deadline of November 2.
