Guest bio
Dr. Staff (Stafford) Sheehan is an American scientist and serial entrepreneur, and the founder and CEO of Project Omega, a nuclear recycling company rebuilding the US nuclear fuel cycle. Project Omega recycles spent nuclear fuel into long-duration, high-density power sources and critical materials for the advanced reactor industry, working with the Department of Energy's Idaho National Laboratory and Pacific Northwest National Laboratory. The company emerged from stealth in February 2026 with an oversubscribed $12M seed round led by Starship Ventures.
Previously, Staff co-founded Air Company, where as CTO he invented a carbon-dioxide-to-hydrocarbon catalysis process — first commercialized as vodka and perfume, then as sustainable aviation fuel, including powering a US Air Force drone on CO2-derived jet fuel. He holds a PhD in physical chemistry from Yale and is a Forbes 30 Under 30 alum.
Key takeaways
America stores ~100,000 tons of spent nuclear fuel across 100+ sites — and that fuel still contains 90%+ of its energy and is 95%+ reusable uranium.
The current US "plan" for waste is largely concrete storage pads plus settlement payments, after the government defaulted on its 1998 obligation under the Standard Contract.
Project Omega's wedge product is a betavoltaic power source built from strontium-90 — a "battery that never dies" over a span of decades.
Recycling first removes the hard-to-contain fission products (strontium, cesium) and shrinks the truly-permanent waste from "the size of a room" to "the size of a tennis ball."
The go-to-market mirrors solar cells: start in high-value government/defense applications, ride the cost curve down toward commercial uses like edge compute and AI power.
Early revenue is the hardware survival strategy — the comp Staff and Matt discuss is Avalanche Energy (a fellow portfolio company), which found ways to earn revenue before the ultimate goal.Links & resources mentioned
