Nuclear energy is one of the most powerful tools available for clean, reliable power, but it has a massive problem holding it back. For decades, the public and politicians have been terrified of what happens after the fuel is used. Tons of spent nuclear fuel sit in concrete silos next to power plants all over the world. Most people view this material as a dangerous, multi-generation liability that needs to be buried deep underground.
But what if the things we call “waste” are actually a country’s most valuable, untapped energy asset? While the world looks for deep caverns to hide spent fuel, a new movement is reframing the entire equation. The material sitting in storage isn’t dead ash; it is packed with unspent power. By changing how we view this material, we can unlock an abundant supply of clean energy and transform a geopolitical headache into a domestic power plant.
The Trillion-Dollar Nuclear Waste Dilemma
The modern nuclear industry faces a massive bottleneck. When nuclear fuel completes its cycle in a commercial reactor, it is removed and labelled as waste. However, the term “waste” is deeply misleading. In reality, this used nuclear fuel still contains over 90% of its original energy. Roughly 96% of the material is reusable uranium.
Because the United States and many other nations have historically maintained a moratorium or a lack of infrastructure for commercial reprocessing, this valuable material just sits there. The current strategy relies on keeping it stored on-site at nuclear facilities, waiting for a permanent underground repository that may take decades to build.
This creates three massive issues. First, it leaves an enormous amount of clean energy completely unused. Second, it costs taxpayers and power companies billions of dollars to monitor and secure these storage sites. Third, it creates a massive geopolitical vulnerability. Right now, the global supply chains for nuclear recycling and advanced nuclear fuel are heavily controlled by foreign adversaries, particularly Russia and China. If Western nations want to enter a new age of nuclear power and satisfy the massive energy demands of modern artificial intelligence data centres, they cannot rely on foreign supply chains. The industry desperately needs a safe, localized, and economically viable way to recycle nuclear material.
Dr Staff Sheehan: The Scientist Entrepreneur Redefining Clean Tech
Dr Stafford W. Sheehan, known professionally as Staff Sheehan, is a scientist and entrepreneur tackling this challenge head-on as the CEO and Co-Founder of Project Omega. Sheehan is a rare blend of an academic elite and a pragmatic, trial-by-fire businessman. Out of high school, he took the civil service exam, trained as a medic, and spent time working as an EMT and firefighter. While doing contract work on the side, he taught himself how to build a software business back in 2006 and 2007.
Eventually, Sheehan realized that software lacked the tangible, physical impact he wanted to make on the world. He shifted his focus to the physical sciences and attended Boston College. Though he originally intended to major in computer science with a minor in Arabic, he changed his concentration after taking a chemistry class his freshman year, earning his undergraduate degree in Chemistry in 2011. He then attended Yale University as a National Science Foundation Graduate Research Fellow, where he earned his PhD in physical chemistry in 2016. At Yale, his research focused on artificial photosynthesis, nanoparticles, and advanced catalysts.
Before shifting his attention to nuclear energy, Sheehan co-founded Catalytic Innovations, an anti-corrosion company spun out from his Yale PhD work that landed him on the Forbes 30 Under 30 list at age 27. He then co-founded Air Company, where he served as Chief Technology Officer (CTO). At Air Company, he invented a groundbreaking heterogeneous catalysis process that captures carbon dioxide and converts it into high-value alcohols and hydrocarbons. To prove the commercial viability of his technology, the company initially produced premium consumer goods, such as carbon-negative vodka, before scaling up to produce synthetic jet fuel for the U.S. Air Force to address critical problems in contested logistics. After successfully demonstrating that greenhouse gases could be converted into valuable commodities, Sheehan stepped back to focus on an even larger bottleneck in the global energy infrastructure: nuclear waste.
Shifting Perspectives: From Carbon Capture to Nuclear Chemistry
Dr Staff Sheehan’s personal motivation is to build hardware that solves structural problems in manufacturing and energy. He realized that society is entering an era of unprecedented electricity demand, fueled heavily by the rapid expansion of AI computing and data centres. At the same time, the global transition away from fossil fuels requires dense, continuous base-load power that solar and wind alone cannot always provide.
Nuclear energy is the obvious answer, but Sheehan saw that the entire venture capital and startup ecosystem was focused on building new types of reactors. Almost no one was developing the technology to handle the fuel cycle’s backend.
Sheehan was motivated by a clear insight: if you want to fix the nuclear industry, you have to fix the waste problem. Furthermore, he saw a massive economic flaw in how the world approached recycling. Traditional reprocessing facilities, like those in France, are massive, government-subsidised infrastructure projects designed primarily to extract uranium and plutonium using complex, aqueous chemical separations. Sheehan realized that if a private company could look at the other elements inside the waste, the valuable transuranic elements and fission products that emit predictable radiation, they could monetize those isotopes directly. This realization transformed nuclear waste from an expensive environmental liability into a highly lucrative commercial resource.
Project Omega: Sourcing Capital and Commercial Partners
Dr Staff Sheehan co-founded Project Omega in 2025, setting up its headquarters in Newport, Rhode Island, to turn this insight into a scalable reality. Operating initially in stealth mode, the startup set out to develop advanced nuclear recycling technology that could safely extract valuable isotopes from used nuclear fuel and convert them directly into electricity.
Rather than trying to build a massive, centralized nuclear facility from scratch, Project Omega focused on cross-industry collaboration and rapid hardware prototyping. The company partnered with the Pacific Northwest National Laboratory (PNNL), a U.S. Department of Energy national laboratory with unparalleled expertise in nuclear chemistry and material science.
To fund this ambitious endeavour, Project Omega emerged from stealth in early 2026 by announcing an oversubscribed $12 million seed funding round led by Starship Ventures, alongside participation from Slow Ventures, Mantis Ventures, Buckley Ventures, and Decisive Point. In tandem with this venture backing, the company secured a critical federal partnership and funding contract with the U.S. Department of Energy’s ARPA-E (Advanced Research Projects Agency-Energy) under the CURIE (Converting UNF Radioisotopes Into Energy) program. This capital allowed the company to assemble a world-class team of nuclear engineers, regulatory experts, and defence builders, including former officials from the Nuclear Regulatory Commission (NRC) and the Department of Defence (DOD). By early 2026, Project Omega hit its first major technical milestone: proving it could successfully convert radiation from spent fuel isotopes into usable electricity using entirely U.S.-made materials.
Navigating Regulatory Hurdles and Handling Isotopes Safely
Building a nuclear startup comes with a unique set of challenges that traditional tech companies never have to face. The regulatory environment is incredibly strict, and the capital requirements for handling radioactive materials are substantial. For decades, a political and legal moratorium on commercial nuclear recycling in the United States discouraged private investment, leaving the field almost entirely to state-backed entities.
To bypass these hurdles, Project Omega had to be strategic about its initial product line. Instead of trying to build large-scale power grid systems immediately, the company applied its technology to compact, highly specialized power sources designed to change the way we think about small electronics. They focused on optimizing advanced alpha- and beta-voltaic technology. This process involves capturing the alpha and beta particles emitted by specific isotopes, like Americium-241 (a valuable transuranic element) and Strontium-90 (a true fission product), and using advanced semiconductor materials to absorb the radiation and convert it directly into steady streams of electricity.
By focusing on these specific emitters, which require minimal shielding and are handled much more safely than high-energy gamma rays, Project Omega created a path to market that bypasses many of the traditional grid-scale regulatory bottlenecks. Their initial prototypes function as compact power cells built to run continuously for decades without ever needing to be recharged or replaced.
Flipping the Script on Waste Management Economics
Dr Staff Sheehan’s expertise lies in his ability to apply the principles of chemical and electrochemical engineering to broken industrial supply chains. Just as he did with carbon dioxide at Air Company, Sheehan looks at industrial systems through the lens of unit economics. He understands that a green technology cannot succeed on environmental goodwill alone; it must be cheaper and more profitable than the dirty alternative.
Under Sheehan’s leadership, Project Omega is completely rewriting the economics of the nuclear fuel cycle. Traditional nuclear economics fail because power plants must pay massive long-term storage fees for used fuel. Project Omega flips this model by sourcing its raw materials for next to nothing. The waste is already sitting in concrete casks next to existing power plants, waiting to be used.
By separating the components of this used fuel, Project Omega extracts high-value isotopes that can be sold into specialized markets. For example, Americium-241 is widely used in commercial smoke detectors and industrial gauging systems, while other isotopes are critical for medical imaging and cancer treatments. The remaining uranium can then be re-enriched and sent back to commercial reactors as fresh fuel. This creates a true circular economy for the nuclear industry.
The CEO’s Vision: Mission-Driven Urgency and Grid Independence
Dr Staff Sheehan’s leadership style as CEO is defined by practical execution, scientific rigour, and national urgency. Having started his career as a first responder, he operates well under pressure and values direct, clear communication. He balances the long-term thinking required for nuclear science with the fast-paced agility of a startup founder. “You can think of a lot of the work that we do as something similar to what you’d see in a semiconductor fab,” Sheehan notes, emphasizing the practical precision required.
Sheehan doesn’t believe in building science experiments that sit in a university lab; he believes in deploying physical hardware in the real world. This mentality is reflected in how he built the team at Project Omega. He deliberately brought together veteran nuclear regulators, military logistics experts, and young, ambitious materials scientists. This unique blend ensures the company can innovate rapidly while staying fully compliant with strict federal nuclear safety guidelines.
Sheehan also leads with a strong sense of geopolitical purpose. He frequently highlights that the United States is lagging behind its global competitors in nuclear recycling and notes that Project Omega aims to directly reduce dependence on Russian uranium or foreign fuel sources. He uses this reality to motivate his team and rally investors, framing Project Omega’s mission not just as a commercial opportunity, but as a critical requirement for national energy security and independence.
Scaling Non-Aqueous Recycling for the Next Generation
The future outlook for Project Omega is expansive. By successfully proving its core isotope-to-electricity conversion technology, the company has set the stage for a massive multi-industry rollout. In the near term, Project Omega is targeting its compact, long-duration power cells at strategic, remote environments where traditional batteries and solar power are useless. These include deep-sea sensors, defence infrastructure in contested environments, space exploration vehicles, and warfighter wearables to drastically reduce the battery weight soldiers carry.
As the company scales its recycling infrastructure over the next 15 to 20 years, the goal is to expand from specialized micro-power cells to macro-power systems capable of supporting commercial infrastructure. Project Omega will validate key components of its platform via kilogram-scale prototype testing alongside the Idaho National Laboratory (INL). Unlike legacy aqueous reprocessing methods that generate large secondary wastewater streams, Project Omega’s approach remains entirely non-aqueous, using molten salts to separate materials through electrochemical processes. The process achieves high-purity separations without isolating pure plutonium, minimizing proliferation risks.
Ultimately, Sheehan’s vision is to build an infinite energy economy. By creating a reliable, domestic supply of recycled nuclear fuel and long-lived radioisotope power sources, Project Omega aims to eliminate the concept of nuclear waste entirely. If successful, the company will not only secure a cleaner planet but will also establish complete energy independence for the next generation of industrial growth.
