In the last two decades, the subject of hydrogen production by sonolysis
(sono-hydrogen) has been widely investigated experimentally and theoretically. This
chapter highlights the recent experimental and theoretical progress in the field of
sonochemical production of hydrogen. The chapter will be divided into two parts: (i)
literature review of the available experimental data (experimental conditions,
production yields, influencing factors) and (ii) a numerical analysis of the treated
subject, with emphasis on the impact of different energetic terms of the bubble energy
balance on the sonochemical yields of hydrogen, all with relation to operational
parameters (frequency, intensity of ultrasound, size of bubble population). The chapter
will be closed with some perspectives on innovation and sustainability of the process.
Keywords: Ultrasound Technology for Fuel Processing
