Experimental testing of a novel sonic method for clean hydrogen generation

This study introduces a novel method for hydrogen fuel generation using ultrasound technology through the disassociation of water into hydrogen and oxygen. The proposed experimental setup comprises several key components: a power supply, an ultrasonic generator, two transducers, a reactor vessel, two vapor traps, a condenser, a valve, a hydrogen storage, a humidity sensor and a hydrogen measurement sensor. The system operates at a power of 100 W and a frequency of 40 kHz, and the reactor vessel contains 2L of solution. The study results show a variability in hydrogen production rates under different experimental conditions. The distilled water used in the experiments at 25 degrees C produces hydrogen at a rate of 0.05 mu mol/min, which increases to 0.066 mu mol/min at 70 degrees C. The tap water gives hydrogen production rates ranging from 0.044 mu mol/min at 25 degrees C to 0.06 mu mol/min at 70 degrees C. The lake water produces hydrogen at rates between 0.036 mu mol/min and 0.054 mu mol/ min, while the wastewater ranges from 0.028 mu mol/min to 0.044 mu mol/min. The present study investigates the effect of CO2 injection into the sonoreactor on the system performance and shows that hydrogen production rates increase over a 20-min period for the water resources, with higher CO2 flow rates leading to improved production rates. These findings demonstrate the potential of ultrasound technology for eco-friendly hydrogen production, marking a promising alternative to conventional methods and contributing valuable insights to the field of sustainable energy.
