Nuclear Batteries
Powering the
Frontier

Harnessing radioisotope decay to generate years of reliable energy from deep sea to deep space.
Delivering to market in 2026

Powering a new era of space missions

Current missions to the lunar surface will survive for weeks and freeze to death during the two-week long lunar night.

Zeno’s nuclear batteries will enable missions to operate for years instead of weeks, providing the necessary heat and electricity to survive extreme cold and darkness.

Enabling seabed resilience

Global conflict has underscored the need for resilient seabed infrastructure.

Zeno’s nuclear batteries will support persistent seabed operations, such as powering maritime sensors and telecommunications cables.
