The need for clean energy to meet the world's increasing energy needs has compelled global leaders to identify other sources of energy generation. Since fossil fuels must be replaced in the energy sector to combat climate change, hydrogen may be the best possible low-emitting alternative energy source. Currently, three energy sources are used worldwide to produce hydrogen: renewable, nuclear, and fossil fuels. Using a bibliometric approach, this study examines how nuclear energy or power has been used to produce hydrogen over the past 20 years. Biblioshiny, a package in R-studio, and VOSviewer were the tools used for the analysis. With an annual growth rate of 7.81%, research on the topic of study has advanced significantly over the years. Over the years, 999 individuals have contributed to the research, using a total of 668 keywords for their studies. Countries with operational nuclear power plants are more interested in nuclear hydrogen production research, potentially due to their quest to diversify their energy use compared to those planning to add nuclear energy. Similarly, studies on how to reduce impact of accidents at such facilities have gained interest since 2010–2023, indicating a growing interest in how to reduce such incidences. The study also identified the trend and evolution of nuclear hydrogen production during the period of study.
