Funded by the Clean Hydrogen Partnership, the HYPRAEL project is developing advanced electrode technologies designed to make green hydrogen production more efficient and cost-competitive with fossil fuels.
The project focuses on improving alkaline electrolysis systems through the use of innovative 3D-structured electrodes. Developed by Veco in collaboration with Fraunhofer, the new electrodes are produced using electroforming technology that enables precise control over thickness, geometry, and structure to match specific electrolyser designs. This “plug-and-play” solution simplifies assembly while enhancing the efficiency of hydrogen and oxygen evolution reactions during water electrolysis.
Early testing shows that the 3D electrodes outperform conventional nickel meshes, reducing cell potential and improving efficiency at high current densities. By lowering electrolyser costs and boosting performance, this innovation has the potential to accelerate the adoption of green hydrogen across sectors such as heavy industry, transportation, and renewable energy storage.
