BASF to upscale green hydrogen production with speciality plastic

Published by , Editorial Assistant
Global Hydrogen Review,


Efficient electrolysers are key in advancing the green hydrogen economy. For the development of electrolysers, BASF offers a partnership to the energy sector: a tailored portfolio of polyarylethersulfones (PSU, PESU, PPSU) for components in water electrolysers used for producing green hydrogen – combined with application know-how and local technical support for part design.

Backed by the company’s understanding of complex injection-moulding applications and membrane casting, they help customers in upscaling electrolyser technology, thus pushing the transformation to clean energy. The portfolio for electrolyser parts includes Ultrason® grades for frames, gaskets and separator membranes.

Ultrason® is suited for metal replacement in various components of alkaline water (AWE), proton exchange membrane (PEM) and anionic electrolyte membrane (AEM) electrolysers. The amorphous polymer shows outstanding temperature and chemical resistance. Its performance under highly demanding conditions includes thermoplastic processing for structural parts and constant high purity for separator membranes. The technology’s temperature-independent mechanical properties make it suitable for current (90 °C) and future (>120 °C) electrolysers.

The polyarylethersulfone also enables long lifetime of electrolysers: it withstands the high compressive forces of electrolyser systems and shows hydrolytic stability. The BASF thermoplastic can be used for small as well as large injection-moulding and extrusion components. This can lead to lower-weight electrolysers and higher freedom of design for different construction needs when compared to metal.
