Innovation News Network: Researchers Boost Green Hydrogen Production With Sound Waves

Engineers in Melbourne have used sound waves to boost production of green hydrogen by 14 times, through electrolysis to split water.

Their invention offers a promising way to access cheap hydrogen fuel for a number of sectors, including transport. The application of green hydrogen in these sectors could rapidly reduce carbon emissions and help fight climate change.

By using high-frequency vibrations to divide individual water molecules during electrolysis, the team managed to split the water molecules to release 14 times more hydrogen compared with standard electrolysis techniques.
