Scaled-up seawater system produces hydrogen and fresh water together

Researchers have built a scaled-up seawater electrolysis system that simultaneously produces hydrogen and fresh water with higher efficiency. Powered by solar cells or other renewables, it could supply hydrogen for ammonia and fertilizer production.

• System combines seawater electrolysis with desalination
• Produces hydrogen and fresh water at the same time
• Can run on solar cells and other renewables
• Hydrogen can be used for ammonia and fertilizers
