The BIOPYRANIA project continues to advance its research activities with the recent delivery of the first bio-based polymers developed by Maastricht University.

These materials are currently being processed and evaluated by project partner Tecnalia, where laboratory-scale anion exchange membranes (AEMs) are being prepared and screened to assess their performance and suitability for clean energy applications.

The evaluation focuses on key properties such as ion exchange capacity, water uptake, and stability. Through the screening of twelve different bio-based polymers, researchers aim to identify the most promising polymer structures and functionalisation degrees for membrane development.

The results will support the selection and optimisation of the most suitable materials, providing valuable guidance for future scale-up activities and further improvements in membrane performance.

Following this screening phase, Tecnalia will continue working on the production of larger-scale membranes and their validation under realistic operating conditions, including testing in anion exchange membrane water electrolysis systems and fuel cell test cells.

By combining bio-based materials with advanced membrane technologies, BIOPYRANIA is contributing to the development of more sustainable solutions for hydrogen production and fuel cell applications, supporting the transition towards a cleaner energy future.
