Introduction
Stargate Hydrogen, an electrolyzer manufacturer from Estonia, has adopted BASF's Ultrason® S to produce frames for its alkaline water electrolyzers (AWE). This high-performance thermoplastic replaces metals like nickel, resulting in lighter and more efficient stacks.
Material Advantages
Ultrason® S offers excellent chemical resistance and stable mechanical properties, even in harsh alkaline conditions. It withstands high stack pressures due to its compression strength and allows for greater design flexibility through injection molding, enhancing functional integration.
Impact on Hydrogen Production
The collaboration between Stargate Hydrogen and BASF has led to the development of pressurized stacks in the Stellar series, designed for long operational lifespans. This innovation supports reliable hydrogen production, reducing downtime and maintenance costs, and improving the economic feasibility of green hydrogen.
Technical Specifications
The patent-pending design of Stargate Hydrogen's Stellar stacks features frames with an 85 cm diameter. BASF's Ultrason® enables these frames to be robust and durable, suitable for current and future electrolyzers operating at higher temperatures.
Future Prospects
BASF's tailored Ultrason® portfolio supports the specific performance requirements of various electrolyzer technologies, including AWE, PEM, and AEM. The material range includes polyarylethersulfones for frames, gaskets, and separator membranes, advancing the scale-up of green hydrogen production.
