Problem
Subsea cable repeaters and deep‑sea sensor networks require reliable, long‑life power sources, but conventional battery or shore‑based solutions are limited by finite lifespan, maintenance difficulty, and the need for frequent replacement in remote ocean depths.
Solution
Apollo Generators provides autonomous radioisotope power systems (RPS) that convert heat from decaying isotopes directly into electricity, delivering over 1 kW of continuous power for more than 20 years. The RTG‑based modules are engineered for integration into submarine cable repeaters, enabling additional petabit‑per‑second capacity and supporting continuous operation of acoustic and environmental sensor arrays without surface power links. By leveraging proven space‑flight thermoelectric conversion technology, the systems operate unattended at depths of 7 km, offering a maintenance‑free power backbone for critical underwater infrastructure.
Target Audience
Primary customers are submarine cable operators and organizations deploying long‑duration deep‑sea sensor networks or autonomous underwater vehicles that require reliable, maintenance‑free power at extreme depths.
