Europe’s Cutting-Edge Direct Seawater Electrolysis Platform
Focusing on Clean Hydrogen Production from Seawater, discover the production of green hydrogen through seawater electrolysis.
SWEETHY introduction
SWEETHY is a 4-year project, co-funded by the European Union, that aims at the development of an innovative electrolysis stack, capable of producing 20 g h-1 of hydrogen directly from seawater.
The project addresses the challenge of processing impure water by leveraging the innovative AEMWE (anion exchange membrane water electrolyser) technology and by developing new, more durable and cost-effective materials, capable of withstanding highly corrosive saline conditions. The developed electrolyser stack will ultimately secure > 2000 h of operation under a 1%/100 h degradation rate.
