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.Traditionally, hydrogen fuel has been made using natural gas, but it can also be made through electrolysis.Electrolysis is a water-splitting reaction that uses electricity to bump hydrogen atoms out of elbow-shaped water molecules, and an…
