NextGen Electrolysis – Wastewater to Green Hydrogen Beta

Wales and West Utilities are partnering with HydroStar, Welsh Water and NGED to look at two demonstrator projects required from new electrolyser systems and the associated electrolyte that ensures resilience of hydrogen supply across the network, giving best value for money and energy security within WWU’s network, along with other UK wide Gas Distribution Network (GDN) customers.

Current electrolysers focus on stack-efficiency and hydrogen purity without considering real-world manufacturing and operational constraints, and the high costs associated. This project focusses on utilising impurified-water, e.g. rainwater, storm-overflow and industrial process wastewater as feedstock, which reduces operational constraints and costs for customers whilst enabling wide-scale uptake of low-carbon hydrogen.
