High performance materials for green H2 production without critical raw materials

EU Funded Project HYScale, has successfully developed and tested high-performance materials that eliminate the need for critical raw materials and PFAS, offering a more sustainable and economically viable solution.

These advances mark a major step towards the integration of the stack into a fully functional electrolyser system, targeting a CAPEX of 400 €/kW and advancing towards validation in an industrially relevant environment.

With the EU aiming to cut greenhouse gas emissions by 40% by 2030—and up to 95% by 2050—there is an urgent need for scalable, sustainable energy solutions. Green hydrogen offers a versatile and clean alternative to decarbonise energy-intensive sectors. However, its widespread adoption depends on overcoming cost, durability, efficiency and resource challenges.

HYScale is addressing this challenge by upscaling innovative high-performance materials that reduce dependency on scarce resources, without compromising on performance or efficiency. By replacing CRMs and PFAS, traditionally used in Anion Exchange Membrane-water electrolyser (AEMEL), the project is advancing the first single stack 100 kW AEM electrolyser prototype, more cost-effective and environmentally friendly for hydrogen production.

The project is supported by the Clean Hydrogen Partnership and its members. Funded by the European Union. A detailed report on HYScale’s latest developments, including technical findings and next steps, is available for download on the project website.
