The EU-funded project HYScale has made significant advancements in the field of green hydrogen production by developing and testing high-performance materials that eliminate the need for critical raw materials and PFAS. These materials offer a more sustainable and economically viable solution for hydrogen production. The project aims to integrate these materials into a fully functional electrolyser system, targeting a competitive CAPEX of 400 €/kW and moving towards validation in an industrially relevant environment. As the European Union aims to drastically reduce greenhouse gas emissions, there is a growing demand for scalable and sustainable energy solutions. Green hydrogen has emerged as a versatile and clean alternative to decarbonize energy-intensive sectors. However, challenges such as cost, durability, efficiency, and resource dependency hinder its widespread adoption. HYScale is tackling these challenges by upscaling innovative high-performance materials that reduce the reliance on scarce resources without compromising performance or efficiency. By replacing critical raw materials and PFAS traditionally used in Anion Exchange Membrane-water electrolyser (AEMEL), the project is advancing the development of the first single stack 100 kW AEM electrolyser prototype, which promises to be more cost-effective and environmentally friendly for hydrogen production. The project is receiving support from the Clean Hydrogen Partnership and is funded by the European Union. HYScale's latest developments, including technical findings and next steps, are detailed in a report available for download on the project website, highlighting the project's contribution to the advancement of scalable and sustainable energy solutions in Europe.
