The article "Emerging Trends and Challenges in Pink Hydrogen Research" by Pablo Fernández-Arias, Álvaro Antón-Sancho, Georgios Lampropoulos, and Diego Vergara explores the development and potential of pink hydrogen, a form of hydrogen produced through thermochemical electrolysis using nuclear energy. The authors conduct a bibliometric review to analyze the landscape of pink hydrogen research, highlighting its growing interest and the challenges it faces. Key findings include: 1. **Growth in Research**: The number of publications on pink hydrogen has increased steadily, reflecting a growing interest in this technology. 2. **Technology Immaturity**: The field is still in its early stages, with limited international strategy and diverse research topics. 3. **Future Potential**: The development of Gen IV nuclear reactors and Small Modular Reactors (SMRs) is expected to enhance the implementation of pink hydrogen. 4. **Key Players**: The United States and China lead in both research productivity and nuclear energy development, indicating their potential for pink hydrogen deployment. 5. **Research Trends**: Keywords analysis reveals a focus on electrolysis, hydrogen production, and nuclear energy, with less emphasis on technical advancements. 6. **Challenges**: Public perception, safety concerns, and regulatory frameworks are significant challenges that need to be addressed. The study concludes that while pink hydrogen is still in its infancy, it holds promise as a sustainable and eco-efficient alternative to conventional hydrogen production, potentially playing a crucial role in the energy transition.The article "Emerging Trends and Challenges in Pink Hydrogen Research" by Pablo Fernández-Arias, Álvaro Antón-Sancho, Georgios Lampropoulos, and Diego Vergara explores the development and potential of pink hydrogen, a form of hydrogen produced through thermochemical electrolysis using nuclear energy.
