ANion Exchange Membrane Electrolysis from Low-grade water sources

Project description

Efficient hydrogen production from low-grade water sources using non-critical raw materials

Hydrogen is abundantly available in water, which is split into its components through electrolysis, a process powered by clean electricity from renewable energy sources, such as solar and wind, ensuring low carbon emissions. The EIC-funded ANEMEL project's anion exchange membranes (AEM) for water electrolysis could replace the traditional electrocatalysts of proton exchange membranes, based on noble and expensive metals, with low-cost and more abundant transition metal catalysts. However, AEM face challenges like low ion conductivity and poor mechanical and chemical stability. The project will therefore develop an innovative AEM electrolyser with improved activity and stability. The goal is green hydrogen from low-grade water sources (such as saline and wastewater) using only non-critical, cheap raw materials.


ANEMEL aims at the development of an anion exchange membrane electrolyzer that operates using low-grade water sources such as saline and wastewater, to produce green hydrogen using renewable sources. The project will achieve this objective by focusing on the preparation of selective and efficient membrane electrode assemblies using non-critical raw materials as electrocatalysts and membranes. The expertise of the consortium in oxygen and hydrogen evolving electrocatalysts, membrane preparation, reactor
engineering and reactor modelling will ensure the delivery of an AEM device capable to operate at low overpotentials, without major water pre-treatment and at a current density above 1 A cm-2. The technical work will be compemented with an ecodesign process supported by an environmental and socio-economic analysis to guide the development of a low impact and circular designed AEM device maximising socio-economic benefits. A techno-economic and exploitation plan to move from laboratory scale single-cell to a multi-stack electrolyser will be studied to ensure a fast-track to commercialisation.
