New electrolyser splits saltwater into H2

Researchers from Shenzhen University and Nanjing Tech University in China have developed a seawater electrolysis system (SES) for the direct electrolysis of seawater, without side reactions or corrosion.

The new method works via self-driven water migration to sidestep the need for a separate desalination process. The energy consumption is purportedly comparable to that of industrial alkaline electrolysis with pure water.
