Zeno Power Systems is a venture-backed startup developing next-generation radioisotope power systems (RPS), often called nuclear batteries. The company's technology converts heat from decaying radioisotopes into long-duration electricity for applications in harsh, remote environments such as space, the seabed, and defense installations. Zeno differentiates itself by using repurposed nuclear materials as fuel, aiming to create systems that are lighter, more affordable, and more scalable than legacy RPS.

Radioisotope Power Systems (RPS)

Nuclear Power SystemsSeed

Zeno Power's core offering is a radioisotope power system that converts the heat from decaying nuclear materials into a reliable source of electricity. These systems are designed to provide continuous power in the range of tens to hundreds of watts for years without maintenance, making them suitable for missions in deep space, on the lunar surface, and on the seabed.

Value Proposition

The technology provides a continuous, resilient power source in remote and harsh environments where conventional power sources like solar panels or chemical batteries are impractical or cannot survive, such as the lunar night or the deep ocean.

Pain Points

Target customers face challenges with conventional power sources that have limited lifespans, are intermittent (like solar), or require complex and costly logistical support in remote environments. Zeno's systems address the need for a reliable, 'always-on' power source that can operate autonomously for years.

Scalable power output, configurable from tens to hundreds of wattsUtilizes repurposed nuclear waste products (e.g., Sr-90, Am-241) as fuelEngineered for high specific power and lower mass through novel fuel and shielding designsProvides years of long-duration, autonomous power in extreme environmentsDesigned with a compact form factor for integration into satellites and other constrained systems
