Hydrogen serves as a pivotal clean energy carrier. However, its production is confronted with efficiency-related obstacles. Direct current triboelectric nanogenerators (DC-TENG) present an environmentally sustainable alternative by transforming mechanical energy into direct electrical power suitable for water electrolysis. This review underscores the progress in DC-TENG mechanisms, advancements in material science, and strategies for effective integration aimed at hydrogen production. DC-TENG attain elevated efficiency levels through the optimization of triboelectric materials, the employment of nanostructured surfaces, and the implementation of scalable designs, thereby facilitating self-sustaining systems for hydrogen generation. Significant advancements encompass enhanced charge density and increased energy output, which contribute to a diminished dependence on external power sources. Nevertheless, challenges persist regarding material longevity, charge transfer efficiency, and the scalability of industrial applications. Future inquiries should emphasize enhancing materials, devising hybrid approaches, and facilitating uninterrupted integration into pre-existing infrastructures. DC-TENG exhibit considerable potential in propelling sustainable hydrogen production and playing a vital role in fostering a cleaner energy future.
