The De Nora Electrode Package is a critical component in alkaline water electrolysis (AWE) systems, designed to enhance hydrogen production efficiency and reduce the total cost of hydrogen (TCO). It features advanced anode and cathode coatings, optimized for high current density and low energy consumption. The package includes bipolar plates, separators, and gasketing systems, enabling it to achieve performance levels closer to proton exchange membrane (PEM) technology while maintaining lower capital expenditure (CAPEX). The package supports various operating conditions and is tailored to meet specific customer requirements, contributing to the energy transition by facilitating green hydrogen production. It is engineered to increase operating current density by more than two times while maintaining or reducing cell voltage, and it ensures a long lifespan with minimal performance drift. The package is essential for achieving sustainable hydrogen production and supports multiple industrial applications, including energy storage, fuel cells, transport, and industrial processes.

Use Cases

  • Green hydrogen production via water electrolysis
  • Energy storage (power-to-power systems)
  • Mobility via fuel cell electric vehicles
  • Chemical production (Power-to-Chemicals: ammonia, methanol, fuels)
  • Decarbonization of industrial processes / hard-to-abate sectors

Capabilities

  • Increases operating current density by more than two times while maintaining or reducing cell voltage
  • Reduces overall power consumption and improves energy efficiency of AWE systems
  • Enables reduction of Total Cost of Hydrogen (TCO) through efficiency and footprint optimization
  • Supports ZERO GAP electrode configuration ensuring stable electrode–diaphragm contact
  • Allows flexible configuration of anode and cathode coatings based on operating conditions
  • Can be integrated into existing AWE electrolyzer architectures
  • Supports dynamic operation following renewable energy power fluctuations
Industrie De Nora S.p.A. Industrie De Nora S.p.A., founded in 1923 and headquartered in Milan, Italy (listed on Euronext Milan since 2022), is an Italian multinational specializing in electrochemistry and a leader in sustainable technologies, playing a vital role in the industrial green hydrogen production chain as the world's largest supplier of electrodes for major industrial electrochemical processes. The company's advanced alkaline water electrolysis (AWE) technology has, in recent years, maximized operating current density and reduced overall power consumption, pushing AWE performance toward PEM electrolysis levels while maintaining lower CAPEX, with De Nora's proprietary electrodic packages enabling the lowest Total Cost of Hydrogen for Power-to-Hydrogen installations -- exemplified by electrodes supplied for McPhy's Augmented McLyzer electrolyzer technology at one of the largest green hydrogen plants in Europe. De Nora holds a 25.85% stake in thyssenkrupp nucera AG & Co. KGaA (a joint venture with the thyssenkrupp group), through which thyssenkrupp nucera has received multiple orders for electrolyzer cells to produce more than 700 MW of green hydrogen via De Nora's subsidiary DeNora Deutschland GmbH, and signed a memorandum of understanding with Asahi Kasei for joint development of small-scale containerized pressurized alkaline water electrolyzers. Generating approximately EUR 853 million in total revenues in 2022, De Nora continues leveraging its century of chlor-alkali and electrochemical expertise -- including deployment of its 1MW-capacity Dragonfly on-site electrolytic hydrogen generation system for hard-to-abate steel production under the European Horizon 2020 HyTecHeat project -- to advance the global green hydrogen economy.
