Electrodes for AWE
The Alkaline Water Electrolysis solution
The most established technology option for producing Green Hydrogen from electrical power sources is Alkaline Water Electrolysis (AWE).
De Nora has a solid Alkaline Water Electrolysis background and, for more than 10 years, has been working on an improved version of this technology.
De Nora's innovative AWE solution allows the reduction of the overall specific power consumption and the maximization of the electrolysis stack operating current density (CD).
BENEFITS
De Nora’s electrodes for AWE help to reduce the stack dimensions (and CAPEX), improve the cell efficiency (and OPEX), and allow the direct coupling of the electrolyzer with Renewable Energy sources.
