High-efficient electrodes for alkaline electrolysis based on electroplating combined with pulsed laser ablation and ex situ sulfiding - H2-ELECTRODE

Project summary

Rationale of the H2-ELECTRODE project is to significantly improve the efficiency of alkaline electrolysers, focusing on the enhancement of nickel foam electrodes. Objectives of the projects are to: • Increase electrode efficiency by expanding and modifying the surface area of nickel as well as reduce the overpotential for H2 and O2 formation. The goal is to decrease OPEX for hydrogen formation by 4-6% beyond the existing 12-14% reduction achieved by ASP. • Extend electrode life by 30-50%, minimising degradation from 0.13% to 0.09% per 1000 hours. • Develop advanced manufacturing processes by utilising Pulsed Laser Deposition and ex situ sulfiding for efficient, large-scale electrode production. The technology will he applied in the new generation of alkaline electrolysers which will significantly boost the production of green H2 for energy storage applications. Impact and potential benefits are lowering emissions in H2 production and contributing to global sustainable energy goals.
