Electrodes for Alkaline Water Electrolysis

Industrie De Nora S.p.A.

Electrode coatings specifically designed for alkaline water electrolysis (AWE) systems
Includes advanced anode (AENRG) and cathode (NRG) coating technologies
Applicable to different substrates, sizes, and geometries
Compatible with all current AWE electrolyzer architectures (pressurized or atmospheric)
Designed for high current density operation and improved system efficiency

De Noras Alkaline Water Electrolysis (AWE) Electrodes Coatings are designed to optimize the efficiency and performance of hydrogen production through water electrolysis. These coatings reduce stack dimensions and CAPEX by increasing operating current density, improve cell efficiency and OPEX by reducing cell voltage, and enhance direct coupling with renewable energy sources. The coatings are tailored for various electrolyzer architectures and are engineered to achieve the lowest Total Cost of Hydrogen (TCO) through reduced plant footprint and optimized power consumption. De Nora offers a range of electrode coatings, including AENR Anodes and NRG Cathodes, which provide significant energy savings and resistance to reversal currents, making them ideal for high-performance AWE systems.

Use Cases

Hydrogen production via alkaline water electrolysis
Energy storage (power-to-power systems)
Renewable energy integration and grid balancing
Mobility via fuel cell electric vehicles (FCEV)
Chemical production (Power-to-Chemicals: ammonia, methanol, fuels)
Decarbonization of industrial processes and hard-to-abate sectors
Water treatment, chlorine, electronics, marine, etc. → company-level only
