Nuclear Batteries Powering the Frontier

Harnessing radioisotope decay to generate years of reliable, clean energy from deep sea to deep space

Delivering to market in 2027

Powering a new era of space missions

Today, lunar missions can survive for only weeks - they freeze to death during the two-week lunar night, when temperatures drop as low as -250°C.

Zeno’s nuclear batteries change that, delivering steady heat and power to keep missions running for years, not days.

Enabling seabed resilience

Global conflict has underscored the need for resilient seabed infrastructure.

Zeno’s nuclear batteries enable persistent subsea operations, such as powering maritime sensors and telecommunications cables.
