If you are a plant operator dealing with high volumes of wastewater—this project developed an AEM electrolyzer that turns waste streams into green hydrogen. This allows you to convert a waste liability into a valuable energy asset without expensive pre-treatment.
Green Hydrogen Production Using Wastewater and Saline Water Instead of Drinking Water
Imagine a machine that makes clean fuel from water, but instead of using precious drinking water, it uses salty or dirty water. It uses special membranes and materials that aren't rare or expensive to keep the process efficient. This means we can produce green energy without taking away water people need to survive.
What needed solving
Green hydrogen production currently relies on high-purity water, which competes with drinking water supplies and requires expensive purification. Additionally, many electrolyzers rely on critical, expensive raw materials that hinder mass adoption.
What was built
An anion exchange membrane (AEM) electrolyzer prototype using non-critical raw materials for catalysts and membranes, designed to work with saline and wastewater.
Who needs this
Who can put this to work
If you are a developer dealing with the high cost of purifying seawater for fuel—this project developed a device capable of operating with saline water. It enables hydrogen production directly from low-grade sources at a current density above 1 A cm-2.
If you are a manufacturer dealing with the high cost of precious metal catalysts—this project developed membrane electrode assemblies using non-critical raw materials. This reduces reliance on expensive metals while maintaining high efficiency for hydrogen production.
Quick answers
How much does the technology cost to implement?
Based on available project data, specific pricing is not provided, but the project focuses on using non-critical raw materials to lower costs and an ecodesign process to maximize socio-economic benefits.
Can this be scaled to an industrial level?
Yes, the project includes a techno-economic and exploitation plan specifically designed to move from a laboratory scale single-cell to a multi-stack electrolyser for commercialization.
What is the IP and licensing status?
Based on available project data, the project is currently in the development phase (2022-2026), and specific licensing terms have not yet been disclosed.
How does it handle water impurities?
The device is designed to operate without major water pre-treatment, specifically targeting low-grade sources like saline and wastewater.
When will the technology be ready for market use?
The project period runs until December 31, 2026, with a fast-track to commercialisation plan being studied as part of the deliverables.
Who built it
The consortium is well-balanced for technology transfer, consisting of 11 partners across 9 countries. With a 27% industry ratio (3 industrial partners) and a strong academic base (6 universities and 2 research institutes), the project combines fundamental material science with practical reactor engineering and commercial exploitation planning.
