In recent years, there has been a notable increase in research efforts dedicated to exploring the production of hydrogen through methane and methanol sonolysis. While experimental studies have been ongoing, a recent shift towards emphasizing numerical analysis has become prominent. This research focuses on the thermal decomposition of methane and methanol within hot acoustic cavitation bubbles, leading to the generation of hydrogen as the predominant product. The chapter delves into the principles of sonochemistry and the process of hydrogen sono-production, providing a detailed overview of various experimental studies conducted in the field of hydrogen production via methane and methanol sonolysis. Furthermore, the chapter offers theoretical analyses for both methane and methanol sonolysis processes, utilizing advanced single bubble cavitation models to understand the impact of different influencing factors on the production of hydrogen. This comprehensive review aims to contribute to the growing body of knowledge surrounding hydrogen production methods and the utilization of methane and methanol as sources for sustainable hydrogen generation.
