Project Omega

America has ~95,000 metric tons of spent nuclear fuel and more than 90% of its energy is still unused. That’s an energy challenge and a national security opportunity. Today, we’re introducing Project Omega as we emerge from stealth. We’re building the next generation of nuclear fuel recycling – designed for safety, proliferation resistance, and real recycling.

We worked with the @ProjectOmegaHQ while still in stealth to help introduce themselves to the world. This is the first of many to come with them.

Your smoke detector contains nuclear waste, Americium-241. So does the fuel powering satellites to Mars. In the latest installment of Principals, @carsonjbecker sits down with @staffsheehan, founder and CEO of @ProjectOmegaHQ, to discuss recycling spent nuclear fuel, the economics of nuclear waste, and the future of nuclear-powered energy systems.

Thank you @ARPAE for the opportunity to brief @LisaSu and @ScienceUnderSec on the great work the @ProjectOmegaHQ and @INL teams are accomplishing!

America is sitting on $500B worth of energy, but many people consider it waste that should be buried. Today, while AI, manufacturing, and electrification push the grid to its limits, there is another option for fueling these innovation generators. @ProjectOmegaHQ has the solution: U.S. used nuclear fuel still holds over 90% of its original energy. Decades of power, already stored here in the U.S. With a newly announced @ARPAE contract and more, Omega is rebuilding the nuclear fuel cycle, turning so-called “waste” into continuous, carbon-free power. The nuclear waste we locked up is the fuel that wins the century. Join us in making this a reality.

High energy prices. Technology acceleration. Supply chain challenges. What if we could tap into something that is treated as waste and instead, view it as a strategic resource? 4.7.2026 #USNuclearRecycling #EnergyAbundance #NationalSecurity @staffsheehan

On your way to San Diego this week to attend the 2026 @ARPAE Innovation Summit? Come visit @ProjectOmegaHQ at our @INL - Omega booth (#427) to learn about our recent ARPA-E award to commercialize the nuclear fuel recycling process. Looking forward to connecting! #USNuclearRecycling #EnergyAbundance #NationalSecurity @staffsheehan

. @ProjectOmegaHQ with @INL has been awarded funding from @ARPAE to advance and commercial used nuclear fuel recycling. “ARPA-E supports efforts that move promising technologies toward real-world deployment,” said ARPA-E Director, @ConnerProchaska . Through ARPA-E’s CURIE program, we’ll validate our molten-salt electrochemical process at kilogram scale, demonstrating a practical, scalable approach to: -Recover energy and valuable isotopes from spent fuel -Strengthen domestic fuel supply chains -Reduce waste and minimize proliferation risks @staffsheehan #USNuclearRecycling #EnergyAbundance #NationalSecurity axios.com/pro/climate-de…

Unleashing the next era of American prosperity. 4.7.2026 #USNuclearRecycling #EnergyAbundance #NationalSecurity @staffsheehan

For decades the United States has led the world in nuclear electricity generation. Now it’s time to lead the way on next-gen reactor deployment.

Help @ProjectOmegaHQ rebuild the nuclear fuel cycle! Omega is growing, and we’re looking for exceptional people to help us tackle one of the most important challenges in energy, national security, and industrial innovation. We’re currently hiring for three key roles: • Head of Regulatory Affairs • Content / Proposal Manager • Molten Salt Engineer If you’re motivated by building something that matters, and working alongside a fast-moving team in the nuclear industry, we want to hear from you. Join a great team and help power what’s next at projectomega.com #USNuclearRecycling #EnergyAbundance #NationalSecurity @staffsheehan

Rebuilding the nuclear fuel cycle is going to be challenging, but the reason we believe it can be done is that our team has experience in a key area: building and commercializing complex chemical and electrochemical technologies. Many of those lessons came from earlier ventures like Catalytic Innovations, a hardware startup spun out of @Yale in 2015 by @ProjectOmegaHQ founder @staffsheehan. The team built the company into a real industrial technology business developing the systems, understanding production, raising capital, delivering to customers, and scaling advanced hardware. Catalytic Innovations has been successfully acquired by a group of chemical and sustainability businesses ensuring these capabilities will continue serving customers across the chemical industry. Experiences like this shape how we approach recycling nuclear fuel at Project Omega. It is not just about the science; it’s the systems engineering, industrialization, and commercialization challenge requiring a team that knows how to move technologies from lab demonstrations to real-world deployment, at speed and scale.

A scientist and serial entrepreneur, @staffsheehan started @ProjectOmegaHQ to develop long-duration power sources and new fuel for nuclear reactors, built from the energy still contained in used nuclear fuel, unlocking new power sources for government, industry, and future energy systems. As @MilanKoch of @mantisVC shared in a @Forbes article featuring Sheehan: “He’s gritty, a phenomenal scientist and a good salesman at the same time. He’s the perfect archetype for this business.” Transforming nuclear waste into a strategic energy resource.

Nuclear is back on the global agenda but amid the momentum around new reactors and SMRs, one critical question remains: where will the fuel come from, and what happens to the waste? Proud to reshare why Pace Ventures invested in Project Omega, written by @MehaignerieG The U.S. alone has more than 100,000 tons of spent nuclear fuel, still containing more than 90% of its original energy. Without mastering recycling, nuclear cannot truly scale. Project Omega is tackling this head-on. The team is transforming used nuclear fuel into long-life nuclear power sources for national security uses and fuel for the nuclear industry. Both areas are key to rebuilding the missing industrial layer of the fuel cycle.

History is full of brilliant ideas consigned to paper because the power wasn’t there. Project Omega is changing that by turning spent nuclear fuel into abundant, resilient energy to drive the next wave of innovations. The future of U.S. energy leadership isn’t just about policy, it’s about unlocking the power that makes this innovation possible. #NationalSecurity #DefenseTech #EnergySecurity @ItsHoagie @StarshipVentures @staffsheehan @Hugo_Peterson6 projectomega.com

What if you could convert the energy of radioactive decay into electricity, via charge separation? @cenmag reporter @CraigBettenhausen took a chemical-minded lense in his reporting to @ProjectOmegaHQ's approach, highlighting how the technology uses the same basic idea as solar photovoltaic cells, but with electrons from radiation instead of photons from the sun. “Recycled nuclear fuel can be the foundation of energy independence by delivering decades-long power for military systems and supplying fuel for advanced nuclear reactors," said @staffsheehan, Omega CEO and co-founder. “We are now building the infrastructure to unleash this energy source.” cen.acs.org/energy/nuclear…
