BASF is advancing the green hydrogen economy by offering a specialized portfolio of polyarylethersulfones (PSU, PESU, PPSU) for components in water electrolyzers crucial for producing green hydrogen. Showcased at Fakuma 2024 in Germany, BASF's Ultrason® grades are designed to replace metals in alkaline water, proton exchange membrane, and anionic electrolyte membrane electrolyzers, offering exceptional temperature and chemical resistance. This unique thermoplastic enables the development of more efficient and durable electrolyzers, leading to increased efficiency in green hydrogen plants. BASF's expertise in plastic processing and membrane production allows for the creation of long-lasting electrolyzers with high compressive strength and hydrolytic stability, resulting in lower-weight components and greater design freedom compared to traditional metal alternatives. Specifically, Ultrason® is recognized for its advantages in membrane applications due to low cyclic dimer content and consistent material quality, making it a market standard in water filtration and dialysis industries. By leveraging their 30 years of experience in plastic processing, material performance, and membrane production, BASF partners with companies to drive innovation in electrolyzer technology. Through a global-local approach, BASF assists in selecting the appropriate Ultrason® grade, providing support from part and tool design to final manufacturing, thereby enabling companies to lead in the electrolyzer market. The use of Ultrason® extends beyond electrolyzers, finding applications in water filtration membranes, household products, automotive components, and aerospace industries, replacing thermosets, metals, and ceramics due to its exceptional properties. BASF's commitment to sustainability includes a focus on improving the entire plastics journey from production to recycling, aligning with the company's vision for a circular economy. With a sales figure of €7.2 billion in 2023, BASF's Performance Materials division is driving innovation in plastics to meet the needs of various industry sectors, emphasizing the importance of sustainable practices in product development.
