Green Hydrogen Production Using Wastewater and Saline Water Instead of Drinking Water

energyPrototypeTRL 3

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.

The business problem

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.

The solution

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 can put this to work

Water Treatment
enterprise
Target: Industrial Wastewater Plant Operator

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.

Maritime & Coastal Energy
mid-size
Target: Coastal Hydrogen Hub Developer

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.

Chemical Manufacturing
enterprise
Target: Green Ammonia Producer

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.

Frequently asked

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.
