Hydrogen is rapidly emerging as a cornerstone of the clean energy transition. Central to its production is water electrolysis, a process that splits water into hydrogen and oxygen using electricity.
The efficiency of this process hinges on the performance of its core components—especially the electrodes. Innovations from Veco are unlocking new levels of efficiency, durability, and scalability.
electroforming and electrolysis
Our unique NiE3 electrodes feature highly controlled and customisable structures that significantly enhance their performance in water electrolysis.The electroforming process allows for the creation of micro- and nano-scale surface textures, which dramatically increase the electrode’s active surface area, promoting faster hydrogen evolution reactions (HER). Veco’s electroforming methods also enable the fabrication of complex geometries that optimise gas release and electrolyte contact, improving overall reaction kinetics.
These electrodes are typically made from high-purity metals, deposited with exceptional uniformity, which ensures excellent electrical conductivity and long-term durability. The precision and scalability of how we use electroforming make it a powerful technique for producing next-generation hydrogen electrodes tailored for high-efficiency, low-energy hydrogen production.
For both the anode and cathode, Veco is able to reduce the cell potential significantly compared to expanded nickel mesh. This effect is larger at high current density,
making the NiE3 structures a perfect fit for use in high performance Alkaline Electrolyser systems.
