Rely Joins TNO VoltaChem's Anion Exchange Membrane Electrolyser Program

Program Overview

The new Shared Research Program, led by TNO VoltaChem, focuses on advancing Anion Exchange Membrane (AEM) electrolysers. This initiative, which began this summer, spans three years and aims to enhance the performance, durability, and cost-effectiveness of AEM electrolyser systems.

Technological Advantages

AEM electrolysers offer a cost-efficient, PGM-free technology for hydrogen production. They utilize a semipermeable membrane to conduct hydroxide ions, separating hydrogen and oxygen while providing electrical insulation. Unlike proton-exchange membrane (PEM) electrolysers, AEM technology operates in an alkaline environment, allowing the use of more abundant and less costly transition metal catalysts like nickel and iron.

Research and Development

The program adopts a precompetitive, open innovation approach to focus on R&D and mitigate technology development risks. While traditional alkaline electrolysis is well-established and PEM electrolysis has been commercialized, AEM electrolysis remains in the early stages of research and development.

Collaboration Opportunities

Participation in the research program is open to other industry players across the value chain, encouraging collaboration to explore technological innovations in AEM electrolysers.
