Abstract: The abundance of hydrogen resources on Earth, their high gravimetric energy density, and their environmental benefits have collectively encouraged the adoption of hydrogen fuel as a clean alternative to fossil fuels. Due to these qualities, hydrogen fuel is emerging as a potential substitute for conventional fossil fuels in the global search for clean and sustainable energy alternatives. However, the creation of reliable, affordable, and effective electrocatalysts is necessary to achieve a sustainable hydrogen economy. This study methodically investigates recent developments and potential future directions in chromium-based transition metal nitrides (Cr-TMN), addressing the urgent need for durable electrocatalysts amidst the global energy crisis and environmental concerns. It carefully examines the production, properties, and electrochemical performance of these materials, particularly focusing on their potential to revolutionize energy storage and conversion technology. This review critically evaluates the global adoption of Cr-TMN, emphasizing their potential to mitigate environmental deterioration and play a crucial role in sustainable energy solutions. This research offer a solid foundation for further studies and policy decisions, underscoring the transformative potential of Cr-TMN in advancing cleaner and more sustainable energy solutions.
