FST outlines critical seal requirements for hydrogen energy systems in new whitepaper

Freudenberg Sealing Technologies (FST) has published a whitepaper addressing the stringent technical demands placed on sealing solutions in hydrogen (H2) energy systems. The document highlights the challenges across the entire H2 value chain—from electrolysers, compression, transport, and storage to fuel cells and hydrogen internal combustion engines. Key issues covered include permeation resistance, explosive decompression risks, and compatibility with extreme media and temperature conditions. The whitepaper provides practical guidance on material selection, design considerations, and relevant industry standards, alongside a checklist for engineers. It also features insights from hydrogen industry experts and an overview of applications and materials suited for H2 environments. FST emphasizes that hydrogen’s role in the energy transition demands sealing solutions capable of withstanding unique operational stresses. The whitepaper is available to subscribers of the European Rubber Journal.
