University of Sharjah researchers have identified a transformative new use for nuclear waste: producing vast quantities of clean-burning hydrogen. Published in Nuclear Engineering and Design, their comprehensive review reveals that repurposing radioactive material could turn a global environmental liability into a powerful asset for the green energy transition, with one method boosting hydrogen yield by up to tenfold.
For decades, the world’s growing stockpile of nuclear waste has represented a monumental environmental challenge. With over 4 million cubic meters currently in storage globally, this long-lived radioactive material requires secure containment for millennia. But what if this perceived problem could become a core part of the solution to the clean energy crisis? A groundbreaking study from the University of Sharjah is proposing exactly that, outlining a future where nuclear waste fuels the production of hydrogen on an industrial scale.
“Utilizing nuclear waste is a novel method of producing hydrogen that transforms a persistent environmental issue into a useful resource,” the research team stated, according to their paper. “Hydrogen has become a promising energy carrier as the need for sustainable and clean energy sources increases globally.” This radical shift in perspective is detailed in their systematic review of advanced technologies that harness radioactivity to split water molecules, a process that produces hydrogen without any carbon dioxide emissions.
The research, reported by the University of Sharjah, critically examines a suite of innovative methods. Among the most promising is radiation-enhanced electrolysis, a novel process that the scientists claim can boost hydrogen yield by an impressive tenfold compared to conventional electrolysis. This technology offers a significantly faster and more efficient route to hydrogen production.
The paper also highlights the cost-effectiveness of uranium-based catalysis, where compounds from the waste itself act as catalysts to speed up chemical reactions. “Using uranium-based catalysts reduces the need for rare and expensive metals,” the authors argued, addressing a major hurdle in scaling up hydrogen technologies.
The study doesn't shy away from the significant hurdles that remain. The researchers identified a "significant obstacle" in the "stringent regulatory framework" governing radioactive materials. “Most of the available literature relies on external radiation sources to simulate the effects of radioactive waste, which may compromise the accuracy and real-world applicability of the findings,” they maintained. While acknowledging that safety regulations are essential, they noted that these strict rules can inadvertently hinder the very innovation needed to advance the field.
Beyond radiation-enhanced electrolysis, the review spotlights other viable techniques. These include feeding radioactive waste into specialized heaters to generate electricity for powering electrolysis cells, and liquid-phase plasma photocatalysis, which can enhance hydrogen production from nuclear wastewater.

The authors found that hydrogen output is significantly affected by several variables. For instance, adding formic acid can increase the yield by up to 12-fold, while higher temperatures can lead to a fivefold increase. Specific catalysts, such as TiO2 (Rutile phase) and ZrO2, were also identified as particularly effective.
The potential advantages of successfully implementing these methods are profound. The researchers emphasized that these techniques “have several advantages, including lowering the amount of radioactive waste, lowering the requirement for long-term storage, and supplying a steady supply of hydrogen.”
This creates a compelling dual benefit: simultaneously reducing a dangerous environmental stockpile while generating a clean fuel. The team concluded that overcoming the current barriers will require a united front. “In order to overcome technical, regulatory, and financial obstacles in the future, it will be crucial to promote cooperation between scientific research institutions, legislators, and industry stakeholders.”
