Materials and Solutions for Electrolyzers

Technology for a clean energy future

The future of sustainable industrial practices relies on hydrogen, a chemical element present on Earth in large quantities combined with other elements. Hydrogen must be separated from those elements to obtain usable hydrogen gas. A key component of the EU’s Green Deal, clean hydrogen is essential to reaching carbon neutrality goals. Electrolyzers are now making green hydrogen production become a reality. According to the Hydrogen Council, the production of green hydrogen has the potential to reach more than 300GW by 2030, as favorable regulations and public funding for clean energy and clean hydrogen will contribute to rapid demand growth for electrolyzer technologies. And while ammonia can be the preferred chemical form for long-distance transport in tanker vessels, all hydrogen needed for ammonia (NH3) production will be made via water electrolysis.

Syensqo's technologies play a vital role in modern electrolyzers, contributing to improved power density, durability and manufacturing productivity, which supports high-volume production. Our commitment to the clean hydrogen market through research, development and product commercialization dates back more than 20 years. The focus on bringing the world closer to net-zero emissions has inspired Syensqo to introduce high-performance water electrolyzer production solutions. Through the pursuit of sustainability and innovation, Syensqo's technologies will help advance the hydrogen economy and make carbon neutrality a reality.

High-performance materials for electrolyzers

Each type of electrolyzer operates under different conditions with unique performance requirements. Syensqo's broad portfolio of specialty materials addresses challenges across electrolyzer technologies. We offer several commercial-grade products ready for use in both prevalent and emerging electrolyzer technologies.

Syensqo's solutions drive hydrogen production. Our high-performance materials find use across various large-scale industrial electrolyzer components, from the core to the balance of stack (BOS), to the balance of plant (BOP) applications.

Alkaline Electrolysis (AEC)

Alkaline electrolysis is used for large capacity operations with multi-megawatt stacks and employs a basic liquid electrolyte of about 70-100°C. For alkaline electrolyzer diaphragms, we offer Udel® PSU as a polymeric binder for the matrix of microporous Zirconia. It works well in alkaline environments as it has excellent resistance properties and is stable over a wide pH range. For cell frames, Udel® PSU, Udel® PSU HYRA, Radel® PPSU HYRA, Ryton® PPS can be used. These materials provide excellent resistance properties and mechanical performance and support lightweight as well as high-volume series production.

Proton Exchange Membrane Electrolysis (PEMEC)

PEM electrolyzers provide exceptionally high power density and efficiency, enabling compact designs and smaller system footprints. PEMECs utilize a solid polymer electrolyte, and operate at increased temperatures and, possibly, increased pressures of 5 MPa or above. PEMECs are associated with intrinsic high-purity hydrogen production. For proton exchange membrane electrolyzers, we offer our Aquivion® ionomers for membranes and electrode binders. Aquivion® ionomers offer good/high proton conductivity with superior mechanical, thermal and chemical stability, widening the electrolyzer operating window. Additionally, Radel® PPSU HYRA is utilized for cell frames, spacers and sub-gaskets in PEMEC, providing outstanding chemical stability and corrosion resistance, along with excellent mechanical retention across a wide temperature range. Tecnoflon® FKM is used for seals in PEMEC, ensuring chemical resistance and durability.
