Good Vibrations Turbo Charge Green Hydrogen Production

The title of this post, is the same as this news item from RMIT University in Australia.

This is the sub-heading.

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

And these are the first two paragraphs.

They say their invention offers a promising way to tap into a plentiful supply of cheap hydrogen fuel for transportation and other sectors, which could radically reduce carbon emissions and help fight climate change.

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

I could understand a two or three times increase, but fourteen times is sensational.

Again, Australia seems to have found the gold through innovative green technology.

Other Benefits

Read the last sections of the news item.

• The process allows the use of cheaper silver electrodes instead of platinum and iridium.
• The engineers also feel that their technique could help in this and other process where bubbles are a problem.

Sound waves have been used for decades for various processes and I am surprised that this appears to be the first time, they’ve applied to electrolysis.

Conclusion

I worked in a hydrogen factory around 1970 and have watched developments over the years.

I am now convinced that an individual or a company will come up with an affordable way to make green hydrogen.

Promising technologies in addition to this one include.

• High Temperature Electrolysis. See Nuclear-Enabled Hydrogen – How It Helps To Reach Net Zero.
• HiiROC See Centrica Partners With Hull-Based HiiRoc For Hydrogen Fuel Switch Trial At Humber Power Plant.
• Electrolysis of sea water. See Torvex Energy.

I can see a combination of a couple of methods.
