University of Sydney Develops Liquid Metal Process for Clean Hydrogen Production from Water
Researchers at the University of Sydney have developed a process using liquid metals to produce clean hydrogen from freshwater and seawater, powered by sunlight. The method achieves a maximum efficiency of 12.9% and utilizes gallium, which can be reused in a circular chemical process. The team aims to improve efficiency for commercialization and establish a mid-scale reactor for hydrogen extraction.

Researchers at the University of Sydney have created a process that uses liquid metals, specifically gallium, to produce clean hydrogen from both freshwater and seawater under sunlight. This method avoids many limitations of current hydrogen production techniques, achieving a maximum efficiency of 12.9%.
Gallium particles react with water to produce hydrogen and gallium oxyhydroxide, which can be reduced back to gallium for reuse, illustrating a circular process. The research team is focusing on improving efficiency and establishing a mid-scale reactor for hydrogen extraction.
