HYScale reveals a PFAS-free electrolyser stack, optimising green hydrogen production with efficiency and sustainability. This technology eliminates harmful chemicals, positioning HYScale as an innovative leader in eco-friendly energy solutions.

A Game-Changer in Green Hydrogen Production

HYScale’s new PFAS-free electrolyser technology marks a significant advancement in the green hydrogen sector. Unveiled on 2 July 2025, this technology eliminates the use of harmful per- and polyfluoroalkyl substances (PFAS), notorious for their environmental persistence [1][2]. HYScale aims to redefine sustainability by offering an industrial-scale solution with a capital expenditure of $428 per kilowatt, targeting robust efficiency and scalability in hydrogen production [3][4].

Innovation at Its Core

This cutting-edge electrolyser stack doesn’t just stop at being PFAS-free. It also negates the need for critical raw materials (CRMs), addressing a recurring challenge in the industry. CENmat played a key role by developing the AionFLX™, a proprietary PFAS-free membrane platform enabling high-efficiency operations [2][4]. The stack boasts a current density exceeding 2 A/cm², nearly tripling the previous industry standards [4].

Collaborative Efforts Foster Progress

The HYScale initiative is a grand European collaboration, intertwining the efforts of the Italian National Research Council and companies like CNR and Bekaert [5][6]. This pan-European approach ensures the development of technology ready to meet the EU’s ambitious climate objectives—a crucial step for making real-world sustainable energy solutions [6].

Environmentally Friendly and Cost-Effective

HYScale’s design embraces affordability by incorporating bipolar plates and transport layers with less nickel. These modifications not only reduce reliance on scarce resources but also make the technology economically appealing [3]. The global focus on reducing dependency on hazardous materials makes HYScale’s innovation timely, with increased regulations on PFAS across various industries [7].

A Broader Implication for Sustainability

Beyond the technology’s immediate benefits, HYScale’s electrolyser aligns with Europe’s broader decarbonisation goals. The project exemplifies a significant reduction in chemical use and enhanced sustainability in industrial applications, positioning HYScale as a leader in the transition to clean energy [1][5].
