Project Omega raises $80M to turn spent nuclear fuel into batteries
What's the deal? Project Omega, a Washington, DC startup developing battery-like power systems from used nuclear fuel, has closed an $80 million Series A, Axios Pro reported. The round is a sharp step up from the $12 million seed it disclosed when it emerged from stealth in February.
What's the company building? Omega's betavoltaic cells convert radioactive decay into electricity, a niche technology suited to low-power, long-life uses such as remote sensors. It also runs a molten salt electrochemical platform designed to recycle spent fuel and recover valuable isotopes.
Why it matters: The round ranks in the 97th percentile of all-time Series A deals in US energy, a sizable bet on a company still moving from prototype toward commercialization.
Why now? Nuclear recycling is drawing renewed federal and private attention. Omega won an ARPA-E contract in April to validate its recycling technology, while the Department of Energy has advanced its Nuclear Lifecycle Innovation Campuses program and rivals like Oklo pursue larger spent-fuel facilities.
What could go wrong? A handful of countries recycle used nuclear fuel, but US efforts have foundered on high costs, thin margins, and low demand. The key test is whether Omega can validate its batteries and make recycling economics work.
The signal: The scale of the round shows investor appetite for nuclear-adjacent bets, but Omega is wagering that a decades-old technology and a difficult recycling market can finally turn commercial.
