Australian researchers use sound waves to expand green hydrogen – pv magazine International

Researchers from RMIT University and the University of Melbourne claim that high-frequency vibrations can release 14 times more hydrogen than standard electrolysis techniques. The discovery has ramifications for the expensive, rare materials currently used in electrolyzers. December 13, 2022 Bella PeacockFrom pv magazine AustraliaAustralian researchers have discovered that sound waves can be used to “divide and conquer” water molecules during electrolysis.“The electrical output of the electrolysis with sound waves was about 14 times greater than electrolysis without them, for a given input voltage,” said RMIT researcher Yemima Ehrnst. “This was equivalent to the amount of hydrogen produced.”The research, recently published in Advanced Energy Materials, could help to bring down green hydrogen production costs.“One of the main challenges of electrolysis is the high cost…
