100 kW Generator
Adélie
Adélie is Endurance's planned 100 kW subsea power system and its first end-to-end deployment: drilling, generation, offtake, and co-located subsea compute in one unit. Built for the Axial Seamount caldera and wired into the OOI Regional Cabled Array off the Oregon coast, it targets a full year of sustained well production.
