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.
