Compact nuclear batteries for the seabed, lunar surface, and deep space — converting decay heat from waste isotopes into decade-long electrical power where solar, lithium, and tethered cables all fail.
Reliable Remote Power
Energy is the binding constraint on persistent operations in the seabed, the Arctic, the lunar surface, and deep space — the strategic domains the US is now actively contesting. Solar fails for two weeks at a time on the lunar night. Lithium chemistry decays in cold, pressurized seawater. Tethered cables can be cut.
The only proven solution at the relevant power band (10s-100s of watts, decade-plus duration) is radioisotope decay — the same technology that has powered every NASA outer-planet mission from Voyager to Perseverance, but historically built one-off at national labs.
Now, Zeno Power is industrializing nuclear battery production with standardized product lines, commercial supply chain, and a price point that supports rate production rather than artisanal one-offs.
Zeno is positioned to be the leader in radioisotope-powered batteries — small, sealed devices that generate electricity for up to a decade from the passive decay of strontium-90 (waste from spent nuclear fuel) and americium-241.
Whether it's enabling moon missions or powering undersea cables, autonomous vehicles and sensing systems, we are excited to back Tyler Bernstein and the Zeno team as they deliver this critical capacity at nation-state scale.
