High-frequency sound waves make electrolyzers produce 14x more hydrogen
RMIT researchers say they've unlocked cheaper, more energy-efficient green hydrogen production with a new electrolysis technique boosted by sound waves. With these high-frequency vibrations active, standard electrolysis produces 14x more hydrogen.

While Hydrogen has a definitive role to play in our future energy economy, we must also be knowledgeable of any potential risks or drawbacks. Just like Nuclear power plants have risks for safety that we can take steps to safely mitigate, hydrogen also has issues that need to be mitigated.

Abstract
Hydrogen (H2) is expected to play a crucial role in reducing greenhouse gas emissions. However, hydrogen losses to the atmosphere impact atmospheric chemistry, including positive feedback on methane (CH4), the second most important greenhouse gas. Here we investigate through a minimalist model the response of atmospheric methane to fossil fuel displacement by hydrogen. We find that CH4 concentration may increase or decrease depending on the amount of hydrogen lost to the atmosphere and the methane emissions associated with hydrogen production. Green H2 can mitigate atmospheric methane if hydrogen losses throughout the value chain are below 9 ± 3%. Blue H2 can reduce methane emissions only if methane losses are below 1%. We address and discuss the main uncertainties in our results and the implications for the decarbonization of the energy sector.
