Melbourne researchers use sound waves to boost green hydrogen production 14-fold

Researchers from RMIT and the University of Melbourne have discovered high-frequency vibrations can release 14 times more hydrogen compared with standard electrolysis techniques. The discovery also has ramifications for the expensive, rare materials currently used in electrolysers. “With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes such as platinum or iridium,” research lead Amgad Rezk said.
