New Prototype Device Generates Hydrogen From Untreated Seawater

Posted by in categories: chemistry, energy

Scientists have found a clever way to generate hydrogen straight from salty seawater. This could be another step towards a clean energy future, if renewables power the process.

The new device makes a few chemical modifications to existing technologies, making it possible to extract hydrogen from untreated, unpurified seawater – which could alleviate concerns about using precious water supplies.

“We have split natural seawater into oxygen and hydrogen… to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyzer,” explains chemical engineer Shizhang Qiao of the University of Adelaide in Australia.
