Introduction Electrochemical water splitting represents a promising solution to the global demand for clean energy carriers, particularly hydrogen. As concerns over fossil fuel depletion and greenhouse gas emissions intensify, hydrogen produced via water electrolysis offers an environmentally benign alternative. The process involves splitting water molecules into hydrogen and oxygen using electrical energy, ideally sourced from renewables such as solar or wind. Despite its conceptual simplicity, the practical realization of efficient water splitting is hindered by sluggish reaction kinetics and high overpotentials. Significant research efforts have therefore focused on developing efficient electrocatalysts and optimizing electrode electrolyte interfaces to minimize energy losses. Understanding the interplay between materials chemistry, electrochemical kinetics, and system design is critical for advancing this technology toward large-scale implementation. Conclusion Electrochemical water splitting continues to evolve as a viable route for green hydrogen generation. Progress in catalyst innovation and system optimization has narrowed the gap between laboratory performance and industrial requirements. However, challenges related to cost, long-term stability, and integration with intermittent renewable energy sources remain. Continued interdisciplinary research combining materials science, electrochemistry, and engineering will be essential to unlock the full potential of water electrolysis in the global energy transition.
