Researchers at RMIT University in Australia have discovered an innovative and promising way to increase green hydrogen production by 14 times by employing sound waves through electrolysis to split water.
According to the engineers, their invention could significantly reduce the costs of producing green hydrogen.
“One of the main challenges of electrolysis is the high cost of the electrode materials used, such as platinum or iridium,” RMIT Associate Professor Amgad Rezk, who led the research, said in a statement.
“With sound waves making it much easier to extract hydrogen from water, it eliminates the need to use corrosive electrolytes and expensive electrodes like platinum or iridium. Since water is not a corrosive electrolyte, we can use much cheaper electrode materials like silver,” Rezk explained.
The research was published in Advanced Energy Material, and an Australian provisional patent application has been filed to protect the new technology, the statement said.
