A Cornell-led collaboration has hit the trifecta of sustainability expertise: The group developed a low-cost technique to supply carbon-free “green” hydrogen through solar-powered electrolysis of seawater. A contented byproduct of the method? Potable water.
The crew’s hybrid photo voltaic distillation-water electrolysis (HSD-WE) system, reported in Power & Environmental Science, at present produces 200 milliliters of hydrogen per hour with 12.6% power effectivity immediately from seawater underneath pure daylight. The researchers estimate that inside 15 years, the expertise might scale back the price of inexperienced hydrogen manufacturing to $1 per kilogram—a key step in attaining net-zero emissions by 2050.
“Water and energy are both critically needed for our everyday life, but typically, if you want to produce more energy, you have to consume more water,” mentioned Lenan Zhang, assistant professor within the Sibley Faculty of Mechanical and Aerospace Engineering in Cornell Engineering, who led the mission.
“On the other hand, we need drinking water, because two-thirds of the global population are facing water scarcity. So there is a bottleneck in green hydrogen production, and…
